CW120 Automatic Checkweigher | High-Precision Online Weight Inspection Machine

The CW120 fully automatic weight inspection machine (also called an automatic checkweigher or checkweigher scale) is a high-performance online weight detection device designed specifically for small boxes, pouches, and ultra-small individual items.

By adopting high-speed A/D sampling and control technology, this checkweigher achieves high-accuracy data acquisition and instant pass/fail judgment during dynamic weighing. It automatically rejects non-conforming products that are underweight, overweight, missing parts, or missing accessories.

The entire checkweigher scale is constructed from 304 food-grade stainless steel. Compact and flexible to install, this online weight inspection machine is widely used in the food, pharmaceutical, daily chemical, electronics, and agricultural product industries. It helps businesses strictly control outgoing product quality, reduce customer complaint risks and material waste, and boost production automation and brand credibility.

Extreme Weighing Accuracy –

Never Miss a Tiny Deviation

- Weighing accuracy of this checkweigher reaches ±0.05g to ±0.1g, with a minimum scale division of 0.01g.

- The checkweigher scale precisely identifies weight differences in ultra-small items such as tablets, small hardware pieces, and candies.

- Effectively avoids regulatory penalties and brand damage caused by non-compliant single-piece or single-pack weight.

High-Speed, Stable Operation –

Match Your Production Line Pace

- Maximum inspection speed of 180 pieces per minute; conveying speed steplessly adjustable from 20 to 60 m/min.
