⚖️ What is a Check Weight (Checkweigher)?
Check Weight, commonly known as a Checkweigher, is an automatic weighing machine installed on a conveyor belt. It is used to check whether the product weight is within the specified limits. It is typically used in quality control (QC) processes on production lines, such as in food, pharmaceuticals, cosmetics, and various industrial products.

- Products are placed on the conveyor belt scale.
- The machine weighs the product while it moves along the belt.
- The system checks if the weight is:
✅ Correct (Pass)
❌ Underweight
❌ Overweight - The machine automatically rejects products that do not meet the weight criteria.
✅ Benefits of a Checkweigher
- Controls product quality
- Prevents underweight or overweight products
- Complies with factory standards like GMP, HACCP, ISO
- Reduces costs from overfilling unnecessarily
- Records product weight data in real-time
