Why Choose MQ-CW3512L1
0.02g Resolution Catches Every Missing Tablet
With 0.02g display resolution and ±0.03-0.1g checkweighing accuracy, one missing tablet in a blister card or one leaflet left out of a carton shows up instantly as a weight deviation. The 1-1000g weighing range covers everything from a single alu-alu strip to full cartons before case packing — all on one machine.
Variable Speed 5-90 m/min
A frequency-controlled motor lets you set belt speed anywhere from 5 to 90 m/min: slow down for small tablet formats where stability matters, or keep pace with your upstream packaging machine when the line speeds up. No more throttling the whole line to accommodate the checkweigher.
Five Rejection Methods to Match Your Product
Air blast, pusher, swing arm, drop flap and tilting flap rejectors are all available. Air blast handles light strip packs without flipping or scattering them; pushers remove cartons cleanly. Matching the rejector to the pack format means defects get rejected and good products never are.
100 Recipes for One-Touch Changeover
Store 100 product recipes on board — recall a recipe and run, no re-entering parameters at every format change. Three-level user access with individual passwords means operators can only select recipes, while parameter editing stays locked to process engineers and administrators, preventing accidental changes that misjudge an entire batch.
304 Stainless Steel, GMP-Ready
The 304 stainless steel housing withstands the daily wipe-downs of a pharmaceutical cleanroom. Hazard warnings, an emergency stop button and safety guards are fitted as standard, meeting pharma-plant inspection requirements for equipment hygiene and operator safety.
Optional Coding, Code Reading and Labelling
Inline coding, inline code reading, read-and-sort, inline labelling and real-time printing are all available as options — the checkweighing station handles serialization and traceability verification at the same time. No extra standalone unit for drug serialization codes, so the line stays shorter and the flow smoother.
Problems It Solves for You
Missing tablets in blister cards and leaflets left out of cartons are caught only by manual spot checks, which never cover the full batch — defects reach the market as complaints, returns or even regulatory notices
±0.03-0.1g accuracy weighs 100% of products inline. The gram-level deviation from one missing tablet or leaflet is detected and rejected on the spot, so no incomplete pack ever leaves the plant.
Frequent changeovers across multiple drug formats take 30 minutes or more of parameter re-entry each time, and one wrong value misjudges the whole batch
100 stored recipes: at changeover, recall the matching recipe on the touchscreen and run. Three-level access control keeps operators from touching process parameters — changeovers are fast and error-free.
When issues arise, no checkweighing records can be produced — failing GMP audits and customer inspections
Checkweighing data exports via USB for archiving, and the optional real-time printer keeps batch records on paper. Complete in-process data is available whenever auditors ask.
Buying separate machines for checkweighing, coding and labelling stretches the line, multiplies failure points and drives up maintenance costs
This machine takes optional inline coding, read-and-sort and inline labelling modules — one station covers checkweighing plus serialization and traceability, and it integrates with cartoners, filling machines and vertical packaging machines.

Functions in Detail
Choosing the Right Rejection Method
Five rejector types are available and configured to order: air blast, pusher, swing arm, drop flap and tilting flap. Rule of thumb: air blast for gram-weight strips and blisters, since it never touches or scatters the pack; pusher or swing arm for cartons with some weight of their own; drop flap or tilting flap where a collection bin sits at the end of the line. Tell us your pack format when ordering and our engineer will define the setup from your samples.
Data Management & Traceability
All machine data exports via USB — pass counts, reject counts and batch statistics can be archived for GMP batch records. The optional real-time printer outputs checkweighing evidence right at the line. Each of the three access levels has its own password, so who changed a parameter or switched a recipe is always traceable, with responsibilities clearly assigned.
Weighing Section Configuration
Standard configuration is 2 conveyor sections (weighing plus rejection), with a weighing section of 350mm long by 120mm wide. For lines with unstable infeed spacing, an optional 3-section setup adds an infeed spacing conveyor so every product crosses the scale individually — preventing false results from products arriving together.
Cleaning & Maintenance
The 304 stainless steel housing tolerates alcohol and standard cleaning agents, meeting daily line-clearance requirements in pharma plants. The variable-frequency motor has a simple structure with few maintenance points; belt changes and deck cleaning need no special tools, so clearance never slows down batch changeover.
Line Integration
Designed as line equipment, the machine integrates with automatic cartoners, filling machines, vertical packaging machines and existing production lines. AC220V±10% power means plug-and-play installation, and the 5-90 m/min adjustable belt speed leaves ample margin for matching upstream and downstream equipment.
Industries & Application Scenarios
Every blister card is weighed as it leaves the blister machine. The fractional-gram deviation caused by a missing or half tablet is identified and rejected instantly — replacing manual counting at the visual inspection station.
Inline inspection at the strip-packing machine outlet. Strip packs up to 200mm long and 120mm wide go straight onto the line, and 5-90 m/min belt speed keeps pace with the strip packer without backing up product.
Integrated with automatic cartoners to catch empty cartons and cartons missing a blister card or leaflet. A pusher rejects them into the reject bin — the final checkpoint before case packing.
Connected downstream of automatic filling machines to verify fill weight vial by vial. The 1-1000g range covers everything from small lyophilization vials to large-format bottles, keeping under- or over-filled vials out of the capping station.
Detects missing capsules or short counts on softgel and tablet bottling lines. With optional inline labelling and read-and-sort, checkweighing and label verification happen at a single station.
Checkweighing of individually packed lightweight items such as test strips and dressings. The 0.02g display resolution is just as sensitive to missing components in gram-level products — incomplete pouches are rejected on the spot.

No, Your Checkweigher Is Not "FSMA 204 Compliant" — Here's the Regulation That Actually Applies
Search "FSMA 204 compliant checkweigher" and you will find vendors selling machines against a rule that says nothing about machines. FSMA 204 is a recordkeeping regulation. Read the text on eCFR and you will find zero equipment requirements — no weighing requirement, no metal detection requirement, no X-ray requirement, no performance specification of any kind. No device can be "FSMA 204 compliant," and no device is "required by FSMA 204." This article explains what the rule actually governs, identifies the regulation that does create the hook for inspection and weighing equipment (21 CFR Part 117 — which itself never names a single machine), and separates net-content law (FPLA, 21 CFR 101.7(q), NIST Handbook 133) from food-safety law, a confusion that costs buyers real money. Includes a myth-versus-fact section, a five-question script for auditing any vendor's compliance claim, and guidance on specifying equipment against the regulation that genuinely applies to your line.
Decoding Checkweigher Accuracy: What "±0.1 g" Actually Means (Sigma Conventions and How to Compare Vendors)
When a checkweigher datasheet says "±0.1 g", that number is meaningless on its own. Accuracy on a dynamic checkweigher is a statistical statement about a distribution of readings, not a hard boundary — and vendors do not use the same statistical convention when they print it. Some quote one standard deviation (1σ, roughly 84% of readings on one side of the distribution); others quote three (3σ, roughly 99.7% coverage). The same machine, the same belt, the same product can be advertised with very different-looking numbers depending on which convention the marketing department picked. This article explains the difference between display division and weighing accuracy — two promises that buyers routinely confuse — walks through what a sigma convention actually commits a vendor to, corrects the most common misconceptions in cross-border checkweigher procurement, and gives you a printable checklist of questions to run against any quotation. It also publishes the real, unrounded specification of the MIQI MQ-CW3512L1 tablet checkweigher as a worked example of what a transparent datasheet should contain.
