Read, measure, and record temperature, humidity, dew point, pressure, and voltage with the multifunction Series PD Pro-Data Programmable Data Logger. The handheld measuring instrument has the capability to record 4000 day/time stamped samples and store data up to 40 days. The nonvolatile memory will retain recorded information in the absence of power to be recalled later. Recorded data can be viewed on the alphanumeric LCD display, sent directly to a printer, or transferred to an IBM compatible computer for later analysis.

The dual channel logger uses plug-in sensors to measure the desired parameters. Sensors are available in three different configurations - temperature/humidity/dew point, temperature/pressure, or temperature/voltage. All sensors are field interchangeable for application flexibility and do not require recalibration when changed. Unit features programmable sampling rate, selectable °F or °C, backlit display, and rear panel keyholes for permanent mounting.
