Weigh Every Pack, Sort Out the Off-Spec

Dynamic weight inspection in motion — the CQ-MN150 weighs every micro product at full line speed and its left-right chute automatically sorts out each underfilled or overfilled pack. A compact bench design with a blue food-grade belt handles up to 2400 pieces per hour, from pharmaceutical blisters and sachets to candies and electronic parts.

Core Engineering

More Than Weighing — A Smart Assistant

Every component selected for one purpose: stable, repeatable readings at production speed, with changeovers measured in minutes.

Three-Stage Isolation

Speed-up, weighing and rejection stages are mechanically separated — belt pull and vibration from adjacent sections never reach the scale platform.

Stable Reading

Left-Right Chute Sorting

Built-in left and right chutes sort underweight and overweight packs out automatically — clean gravity sorting with no moving parts.

Automatic Sorting

Digital Sensor & Zero Tracking

High-precision digital load cell with fast sampling and automatic zero tracking — long-running stability without frequent manual calibration.

0.1 g Resolution

Touchscreen & 200 Recipes

Colour touchscreen with self-learning setup — store 200 product parameters, switch products in minutes without re-engineering.

Self-Learning

Compact Bench Design

Ultra-compact 523 mm footprint with adjustable feet — drops into any line or bench without re-engineering your layout.

Space-Saving

USB / RS232 / RS485 & Excel Reports

Built-in statistics with EXCEL-format reports, USB storage for 1+ years of data — full traceability for audits and process control.

Data Traceability
Rejection System

Left-Right Chute, Zero Leakage

Built-in left and right chutes sort out every underfilled or overfilled pack at full line speed — no air, no pusher, just clean gravity sorting engineered for micro products.

Left Chute Reject Underweight packs are guided out to the left chute
Right Chute Reject Overweight packs are sorted out to the right chute
Gravity Sorting Contact-free chute sorting — no moving parts, no product damage
