Fluke Calibration 1620A-256 Precision Thermo-Hygrometer

The Fluke Calibration 1620A-256 Calibrated Precision Temperature and Humidity Meter is an instrument used to measure temperature and humidity with high precision and accuracy. Fluke Calibration 1620A is mainly used in calibration laboratories, research facilities, and industrial environments where temperature and humidity control is critical.

The standard precision sensor (type “S”) reads temperatures within ±0.25°C within its calibration range from 15°C to 35°C. The relative humidity index is within ±2% RH from 20% RH to 70% RH. All DewK sensors come with an NVLAP-accredited calibration certificate for temperature and humidity, with NIST data and traceability.
