Fluke Calibration DewK Sensors

These replacement sensors work with the Fluke Calibration 1620A DewK (formerly Hart Scientific) digital temperature and humidity logger. The sensors are calibrated for both temperature and relative humidity. Two sensor models are available. The standard accuracy model reads temperature to ±0.25°C over its calibrated range of 15°C to 35°C. It records humidity to ±2% RH from 20% to 70% RH. The high accuracy model reads temperature to ±0.125°C over its calibrated range of 16°C to 24°C. It measures humidity to ±1.5% RH from 20% to 70% RH. Both sensors can also measure temperature below their respective calibrated ranges to 0°C and above their respective calibrated ranges to 50°C with typical accuracy of ±0.5°C. And RH readings from 0% RH to 20% RH and from 70% RH to 100% RH are typically within ±3%.

The sensors are available either as stand alone products or as part of a kit which includes the sensor, sensor case, sensor wall mount bracket and a 25 foot sensor extension cable.
