Product Description

XP201 Highest Precision Temp/Humidity, CO2 Meter, Case, Sensor
The XP-201 is the perfect choice when highest-precision measurements are needed for industrial temperature and humidity (CO2 optional sensor) calibrations. It is suitable as a humidity reference in climate chambers or humidity generators. A mini USB interface with software and online data collection are included.

Supplementary description: The most accurate handheld device (0.5%) for relative humidity. Ideal as a reference standard. Excellent stability, very good repeatable measurements, absolute hysteresis latitude as well as no drift of the measurement value at very high humidity levels. For traceability to national standards a DAkkS calibration certificate is attached.

Special features Included: XP-201 0.5% RH accuracy meter, high quality watertight case, 8130.TFF sensor, 2m cable, batteries and DAkkS calibration certificate are all included.

See our Video/Docs tab above for more detailed information and the calibration certificate.
