Our Highest Precision Hand-Held Temp/Humidity (CO2 with optional sensor) Meter with Watertight Case, 8130.TFF Sensor, Cable and Batteries!
Model: 5810-20
NIST Certification available.

Highest-precision measurements for industrial temperature and humidity calibrations The XP-201 (Model 5810-20) is the perfect choice when highest-precision measurements are needed for industrial temperature and humidity 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.

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: 0.5% accuracy, high quality watertight case, resistive-electrolytic sensor, 2m cable, on/off switch, Touch Screen, batteries and DAkks calibration certificate are included.

Two page brochure here. See optional 8120-TFF (Temp/RH) and 7120-CO2 (CO2) sensors for use with this meter.
