The Fluke 1620A Digital Thermometer-Hygrometer (DewK) measures temperature to ± 0.125 °C and humidity to ± 1.5 % on two channels, and displays it on a big, clear screen. Ethernet, wireless (optional), or RS-232 will allow you to network as many Fluke 1620s (DewKs) as you’d like. And the LogWare III software will allow real-time logging of multiple Fluke 1620s (DewKs), data storage to your computer and seamless integration with MET/CAL® software.
The 2456 Laboratory Environment Monitor (LEM) measures barometric pressure, ambient temperature, relative humidity and air density. The LEM transmits these measurements via an RS-232 or RS-485 interface to a PC. The supplied software can be used to monitor and log all the above parameters for up to eight LEMs simultaneously.
