When does the calibration certificate expire? How long is it valid for?

Asked by: tetratek
Hi Tetratek Thank you for the inquiry. We suggest to use 1 year calibration cycle starting from the time you place the instrument in to service. Best regards OMEGA

How quick is the response/change in readings? I may take a reading at one location, then move to another location for another reading - how fast does this unit adjust/stabilize for a new value?

Asked by: MarkW
Depending on the air flow you should probably expect about a 1 minute response time on the RH to reach the full stable reading. Temperature would be less than 10 seconds to register the stabilized reading.
