Fluke 1620A-S-156 DewK Thermo-Hygrometer, standard accuracy

Model: 1620A-S-156

Measures temperature to 32.45°F (±0.25°C) and humidity to ±2% on two channels and calculates dew point, heat index, and rates of change for both temperature and humidity. On-board memory to store up to 400,000 date and time stamped data points.

Temperature and Humidity Data Logger with Temperature Range from 15 to 35°C

The standard-accuracy sensor (“S model) reads temperature to ± 0.25 °C over its calibrated range of 15 °C to 35 °C. Relative humidity readings are to ± 2 % RH from 20 % RH to 70 % RH.

All DewK thermo-hygrometer sensors come with NVLAP accredited certificates of calibration for both temperature and humidity, complete with data and NIST traceability.

Features:

Huge memory
Upgraded software
Superior accuracy
Network enabled
Powerful logging and analysis tools
Two interchangeable calibrated sensor
