RH-02 calibration validity

Post by mlecompt » Fri Oct 31, 2003 12:22 pm

We use a calibrated RH-02 for validation tests, and need to define an adequate validity time for it's calibration:
Have you got any specification, measurement or estimate for the RH-02 ageing (temperature and humidity?)

If not, how long do you guarantee the specified RH-02 measurement accuracy for ?

Hi,

The manufacturer calibration which is defined as putting in the two numbers, High and Low into RH02 Calibration program should not go out of specifications during the units life time.

However, further calibration National Standards, UKAS would need to be repeated yearly, as these certificates are only valid for one year from date of issue.

Best regards,
