The standalone Check Weigher (CW series) is a specialized weight inspection device engineered for precision weighing in high-volume production and packaging lines. Unlike combined systems, it focuses exclusively on weight verification, leveraging premium components such as the German HBM fast load cell (for rapid measurements), Japanese Oriental motor (for smooth conveyor operation), and Danish Danfoss frequency converter (for consistent speed control). Available in multiple models (1200g, 31000g, 10~4000g ranges) to suit applications from micro-sized electronics to large consumer goods, it uses intelligent product study for auto-parameter setting and a Weinview industrial touch screen for intuitive use. This makes it an essential tool for businesses prioritizing weight accuracy, operational efficiency, and throughput.
The micro-sized model offers a 0.01g Minimum Scale—the highest precision in the series—ideal for micro-products like pharmaceutical tablets or electronic chips. Other models feature 0.1g Minimum Scale, with accuracy ranging from ±0.1g to ±0.5g, meeting the strictest industry tolerances for weight consistency.
Designed for maximum efficiency, the compact model achieves 200 pcs/min (the fastest in the series), while mid-sized and large models reach 150/120/100 pcs/min. This is enabled by ultra-fast dynamic weight tracking and automatic compensation technology, minimizing delays for fast-moving products in high-volume lines.
All models feature CNC-machined structural components for superior dynamic stability, preventing wobble during operation. The 304 stainless steel frame resists corrosion and wear, making it suitable for wet/dusty environments (e.g., beverage bottling plants or agricultural product processing). Multiple filtering algorithms reduce interference from nearby equipment, ensuring consistent, reliable results.

In food production (e.g., packaged snacks, frozen meals, bottled sauces), the checkweigher ensures each product meets precise weight specifications for regulatory compliance and fair trading. It verifies fill levels, detects underweight packages to protect brand integrity, and flags potential overweight giveaways to reduce costly product giveaway. This supports adherence to key industry standards like HACCP, FDA, and GMP, enhancing overall production control and consumer trust.
For chemical and pharmaceutical products (e.g., detergent pods, fertilizer bags, medication bottles), the system guarantees exact weight accuracy in dispensing and packaging—critical for formula consistency, safety, and regulatory compliance. It ensures each batch meets strict weight tolerances, preventing under-dosing or over-dosing while verifying package integrity. This process aligns with stringent quality protocols such as cGMP, ensuring traceability, production reliability, and compliance with industry-specific regulations
It stores up to 50 product programs, allowing quick setting switches (e.g., from smartphone cases to batteries in electronics assembly) without manual reconfiguration.
Yes, the data log can be exported to computers via USB (optional accessory), enabling remote review, data analysis, and integration with quality management systems.
It operates on AC 220V 1Phase (200W, 50/60 Hz adaptive), easily integrating into global production facilities without the need for specialized power modifications.
