NABL accredited
Calibration you can defend
Accuracy is only meaningful if it's traceable. Every Esspron device is calibrated against NABL-accredited standards, and our recalibration program keeps it that way.
[01]How it works
From dispatch to recalibration
01
Certified on dispatch
Each device ships with a NABL-accredited calibration certificate valid for 12 months.
02
Annual recalibration
Send units back for recalibration to keep accuracy within spec and results defensible.
03
Documented results
Receive fresh certificates and traceable records for audits and compliance.
