Two types of sensors are available.
The high-accuracy sensor (?H model) reads temperature to ? 0.125 ?C over a calibrated range of 16 ?C to 24 ?C. Relative humidity readings are to ? 1.5 % RH from 20 % RH to 70 % RH.
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 Fluke 1620A (DewK) thermo-hygrometer sensors come with NVLAP accredited certificates of calibration for both temperature and humidity, complete with data and NIST traceability.
Ethernet capability
With its built-in Ethernet RJ45 jack, multiple Fluke 1620A (DewK) thermo hygrometers can be monitored from the same screen using LogWare III client-server software. Ethernet also gives you the possibility for remote connectivity over the internet, so you can monitor critical conditions while you?re away.
If you need a printout, send data to a printer through the RS-232 interface in real time.
Calibrated sensors
With inputs for two sensors, each measuring both temperature and relative humidity, one Fluke 1620 (DewK)can monitor two locations at the same time. Both sensors can be run via extension cables to remote locations up to 100 feet away, or one sensor can be directly mounted to the top of the DewK.
Each sensor is calibrated for both temperature and humidity by Fluke Calibration. The calibration constants assigned to the sensors reside in a memory chip located inside the sensor housing, so sensors may be used interchangeably between different Fluke 1620 (DewKs), and the recalibration of sensors doesn?t require an accompanying Fluke 1620 (DewK).
Sensors may also be assigned a unique identifier (up to 16 characters) to facilitate record keeping by matching the sensor identifier with the collected data. Each DewK ships with one sensor, with additional sensors available from Fluke Calibration. Spare sensors may also be purchased as a kit, which includes a wall mounting bracket and a 25-foot extension cable.
The DewK thermo hygrometer and humidity monitor has enough on-board memory to store up to 400,000 date- and times stamped data points. That?s two years? worth of data for both measurements from two sensors if readings are taken every ten minutes.
