Quick packer checks using the UK “3 packer rules” (Average, TNE, and Maximum Error).
3 packer rules
Average Quantity Rule: On average, the actual contents (weight or volume) of all packages in a batch must equal or exceed the nominal quantity stated on the label.
Tolerable Negative Error (TNE) Rule: Only a small percentage of packages in a batch are allowed to be slightly underweight (below the nominal quantity by a defined amount called the Tolerable Negative Error, or TNE).
Maximum Error Rule: No single package can be underweight by more than twice the Tolerable Negative Error (TNE).

Barcode Checker
Barcode Checker
Scan and compare barcodes (reference vs check), or generate a barcode for manual verification.
Barcodes render using CODE128. Most scanners will paste into the field automatically.

AQL Calculator
AQL Calculator
Calculate sample size and accept/reject points from lot size, inspection level, and AQL values.

SG Cup Calibration
SG Cup Calibration
Calibrate an SG cup using water density vs temperature, check tolerance (PASS / FAIL), and generate a correction factor.
Actual volume = weight ÷ water density. PASS if |deviation %| ≤ tolerance.
