Waterproof Check Weigher: The Scale That Outlives the Hose, the Freezer and the Brine
Most "waterproof" scales don't fail on the weigh — they fail on the washdown, the condensation and the salt. This one is built so the three things that kill a wet-area scale are the three things it was designed around.
A Post-Mortem on the Last "Waterproof" Scale You Bought
You already own a scale someone sold as waterproof. Here is, in plain terms, how it died — because the same three failures are waiting for the next one you buy unless the build specifically prevents them:
Death #1 — water got past the cover. A high-pressure spray drove moisture into the electrical box and the load-cell junction. The unit was splash-proof, not jet-proof, and nobody asked what IP rating do I need for a washdown check weigher before it was installed. Three weeks later the reading wanders and the box corrodes from the inside. (Could a check weigher survive high-pressure washdown and chlorine? Only if the enclosure is sealed to the jet, not the splash.)
Death #2 — condensation moved the zero. The line runs cold, the air is warm, water films the weigh path, and the tare creeps every time the temperature swings. A scale that can't manage condensation can't hold a number in a frozen or chilled hall — and are stainless check weighers fully submersible or just splash-proof is the wrong question if the real enemy is the water that forms on the belt, not the water you spray.
Death #3 — the salt ate the steel. Brine, sea water and chloride foam sit in every weld and ledge of a 304 frame, and pitting corrosion blooms under the cover. The structure that was supposed to be "stainless" becomes the contamination source and the calibration drift your audit then writes up.
Three deaths. Three causes. The Waterproof Check Weigher answers each one by design, on the spec sheet, not in the brochure.
The Solution: Three Enemies, Three Built-In Answers — On One Standalone Model
This is not a dry scale with a cover bolted on. Model TY-JYP101P220-02-12 is a complete wet-area check weigher whose three headline features map one-to-one onto the three failures above: a waterproof electrical enclosure keeps the jet and the foam out of the electronics (Death #1); an anti-condensation structure keeps the weigh path dry and the zero stable through cold-to-warm swings (Death #2); and a 316 stainless, salt- and sea-water-resistant build shrugs off the brine and chloride that pit ordinary stainless (Death #3). On top of that it carries a −40 °C to 40 °C operating envelope, so it can sit at the edge of a freezer or a chilled hall and still read true.
Because the washdown, the condensation and the chemistry no longer attack the instrument, the sanitation and the cold stop stealing your opening minutes — the scale is accurate the instant the line restarts, the data trail stays defensible, and the OEE you lose today to drying, re-zeroing and corrosion simply comes back. And because it is a full model with its own range and speed — ≤1 kg at ±0.3 g, up to 160 pcs/min — you get wet-area protection without giving up the throughput or the precision a dry line would have.
Core Advantages: Four Ways This Build Beats the Wet Area
A Waterproof Enclosure That Takes the Jet — Not Just the Splash
The electrical box, load-cell junction and cable entries are sealed as a system, so a high-pressure spray washdown and chemical foam stay outside the electronics instead of wicking in. The scale doesn't short, drift or corrode from the inside, and you stop writing off sensors that the washdown quietly drowned — which is the direct answer to whether a check weigher can survive high-pressure washdown and chlorine: yes, when the enclosure is sealed to the jet.
️An Anti-Condensation Build That Holds Zero From −40 °C to 40 °C
The structure is engineered so condensation neither pools on the weigh path nor fogs the sensing, and the rated envelope runs from −40 °C to 40 °C. On frozen, IQF and chilled lines the tare stays put through every cold-to-warm swing, the first packs out of the freezer edge are weighed correctly, and the "re-zero after every defrost" ritual that eats your opening shift simply disappears.
316 Stainless With Salt- and Sea-Water Resistance as Standard
The frame is 316 stainless — not 304 — and the build is specified to resist salt water and sea water, so brine, halide foam and chloride cleaning agents pit nothing that carries a load or a signal. On seafood and salted-product lines the structure and the calibration hold for years instead of months, and the frame stops being the hidden corrosion source your audit flags.
Wet-Area Protection Without the Speed or Precision Penalty
A sealed, cold-rated, corrosion-proof build usually means a slow, coarse scale — not here. This model runs 30–100 m/minat up to 160 pcs/min with ±0.3 g accuracy and a 0.1 g division on a 400 × 220 mm belt. You keep single-pack precision and high-speed throughput inside the splash zone, so going waterproof no longer means choosing between a clean line and a fast, accurate one.
Application Scenarios: Built Around What the Sheet Says It's For
Shellfish & Crustacean — Hard Shell, Slime and a Salt-Water Bath
How do you choose a waterproof check weigher for a seafood plant? Start with the chemistry on the belt. Crab, shrimp, prawn and shellfish packs arrive wet, salty and slime-coated, then the line is blasted down. The 316, salt- and sea-water-resistant frame sheds the brine, the waterproof enclosure keeps the spray out of the electronics, and the open, drainable geometry leaves nowhere for slime to set — so the scale that stands in the splash zone is also the one that passes the hygiene check.
Whole Fish, Fillets & Salted / Cured Seafood — Brine as a Constant
On salting, brining and curing lines the product is the corrosion agent. Whole fish and fillet trays carry halide across the belt all shift, which is exactly why this model makes salt-water resistance and 316 standard rather than optional. The IP69K check weigher for a seafood processing line holds its calibration under continuous brine exposure, and the sealed sensing path means the salt never reaches the component that decides the weight.
❄️ Frozen & IQF Seafood — Condensation and the Freezer Edge
Washdown check weigher for frozen food packaging is where the anti-condensation structure and the −40 °C rating earn their keep. Frozen and IQF packs fog every warm surface they pass; the belt and weigh path are built so that film doesn't form or doesn't shift the tare, and the electronics are rated for the cold hall. The result is stable single-pack weighing right at the freezer discharge — no warm-up drift, no re-zero between runs.
The same wet-area platform is also configured for:
Meat & poultry — an IP66 check weigher supplier for meat and poultry build, where blood, fat and aggressive disinfection demand the same sealed, drainable, 316 logic (IP65 vs IP69K — which is better for meat processing? when the foam is chlorinated, IP69K).
Ready meals, prepared food & dairy — a hygienic check weigher for ready meals and prepared food, and a custom waterproof check weigher line for dairy, with quick-release belts and full cleaning access.
Fruit & vegetable washing lines — a stainless steel check weigher for a fruit and vegetable washing line that lives in continuous, soil-laden spray and still drains clean.

FAQ: The Three Questions This Spec Sheet Actually Answers
Q1: You list 316 stainless as standard — for a seafood line, do I really need 316, and what does it buy me over 304?
On a dry line, 304 is usually fine; on a line that sees brine, sea water or chloride cleaning agents, 316 is the difference between a frame that lasts and one that pits. The molybdenum in 316 resists chloride-induced pitting and crevice corrosion that 304 cannot, which is exactly the failure mode on seafood and salted-product lines — and it's why this model makes 316 and salt/sea-water resistance standard instead of an upgrade you find out you needed after the first corrosion spot appears.
Q2: The sheet says −40 °C and "anti-condensation" — can it really sit at a freezer or IQF discharge, and will condensation still move the zero?
Yes, that pairing is the point. The −40 °C to 40 °C envelope means the electronics and mechanics are rated for the cold hall and the freezer edge, and the anti-condensation structure keeps moisture from forming a film on the weigh path or fogging the sensing as the temperature swings. So the tare holds through cold-to-warm transitions and the scale reads true straight after a defrost or a wash — no warm-up drift and no re-zero ritual eating your opening minutes. (And if your question is really "how much does an IP69K check weigher cost for a frozen line" — you get that number with the matched spec, not after a wrong one fails.)
Q3: The reject is pusher by default — can I have air-blast or a diverter for my wet line, can the line run left-in/left-out, and what's the lead time on a custom build?
All configurable. The standard single-side pusher can be swapped for air-blast, a turning rod, or a diverter/flap (or another method on request) to suit your pack and your hygiene rules, and the operating direction can be set to left-in/right-out or left-in/left-out to match your floor plan. For a custom waterproof check weigher line, the process is drawing-first: send product size, mass, speed, washdown and direction, we return a matched layout with the reject method and a firm lead time, and nothing is built until you sign the drawing — voltage and air supply for your site confirmed in the same step.
Stop Buying "Waterproof" Scales That Aren't — Spec This One to Your Washdown First
The three failures at the top of this page all have one root cause: a scale specified to the product, not to the water, the cold and the salt it actually lives in. We reverse that. Tell us your product, your speed, your hall temperature and — above all — your washdown and your chemistry, and our engineer returns the matched ingress protection (IP65 / IP66 / IP69K), the 316 and sealing configuration, the reject method and direction, and a firm quote on model TY-JYP101P220-02-12.
Whether you need a single IP69K check weigher for sale, a custom waterproof check weigher line, or you just want the waterproof check weigher price list for this round's budget — buying direct from the manufacturer means the protection you pay for is the protection that's built in, on the sheet, before the first wash.
