Single Point RH NIST 50% @ 25C

$224.00

Testing and certification of HOBO data logger and sensor RH (relative humidity) accuracy using standards traceable to the U.S. National Institute of Standards & Technology (NIST).

Contact us for details

Onset offers testing and certification of HOBO data logger and sensor RH (relative humidity) accuracy using standards traceable to the U.S. National Institute of Standards & Technology (NIST). This includes single-point (50% RH @ 25C) or three-point (25, 50, 75% RH @ 25C) NIST certification. For each data logger certified, a certificate is provided showing the device’s RH and temperature accuracy vs. a NIST traceable standard. Certification is available for all currently manufactured Onset data loggers and sensors.

NOTE: The temperature value used for RH certification is fixed at 25C and verified against a NIST-traceable 200-ohm platinum RTD (resistance temperature detector). If additional temperature certification is required at temperature values other than 25C, Onset’s temperature NIST certification services must also be performed. Onset’s temperature NIST services offer certification in an oil-bath for user-selectable temperature points between -30 and 120C. If custom temperature points are desired additional cost and lead time will apply.
