Weight Checker ZJ-300

Keypack Intelligent Weight Checker ZJ-300 is an automatic checkweigher designed for high-speed production line quality control. It delivers accurate weighing detection with a large-size color LCD touch screen HMI and patented weighing frame technology. Ideal for food packaging inspection, pharmaceutical weight verification, and automated package weight inspection across multiple industries.

Product Overview

The ZJ-300 Automatic Checkweigher is a digital weighing cell-based in-line checkweigher engineered for reliable weight detection in fast-paced production environments. Featuring a user-friendly touch screen HMI interface with multi-language support (customizable, default Chinese and English), this weight detection machine stores up to 100 product test data sets for seamless operation. The Keypack Intelligent (kunbupack) checkweigher system integrates photoelectric automatic empty bag detection, adjustable conveyor belt speed, and an automatic learning system to optimize performance. With password-protected parameter settings and automatic zero-point tracking, the ZJ-300 ensures stable performance and accurate weighing throughout production runs. The detachable conveyor belt design with buckle-type structure simplifies cleaning and maintenance, making it an easy maintenance solution for demanding production lines.
