Every instrument has its own calibration record
100% individual calibration — no batch sampling
A gauge looks simple, but if accuracy, hysteresis, pointer stability or sealing fails, it becomes a wrong decision on site. That is why every instrument passes five checks:
- Incoming inspection — bourdon tubes, movements and cases sampled per batch for material and dimensions
- In-process — 100% weld strength and leak testing
- Indication — point-by-point comparison on deadweight testers or digital benches
- Overpressure and return error — 1.25x range for one minute, hysteresis recorded
- Appearance and packing — dial, pointer and nameplate verified item by item
Traceable calibration data
Calibration records are filed by serial number for five years. Give us the serial number and we can retrieve the original curve within 30 minutes.
