Every electronic measuring device will only give correct results if it is checked regularly, i.e. calibrated correctly and adjusted when required. An electronic measuring device is only a reliable measuring and checking tool if it is calibrated and this calibration is documented as part of a quality procedure.
We are pleased to offer you the factory calibration of KERN refractometers (except models ORA 6HA and ORA 1GG) as well as third-party products on demand in our ultra-modern laboratory within fastest processing times (3 working days)..
During this calibration the manufacturer or customer tolerances are checked and readjusted if desired. The conformity of the tolerances is confirmed in the calibration certificate.
The refractive index standard is traceable to SRM (standard of reference material) of NIST (National Institute of Standards and Technology) and PTB (Physikalisch-Technische Bundesanstalt).
