For environmental recording of temperature, humidity, and barometric pressure with an easy to read digital display, our new TR-71U/72U or 73U will meet your requirements. These lightweight instruments include a multi-channel measurement with the capability to store 8,000 readings per channel on board with 15 selectable recording intervals.
For temperatures only, you'll love the TR-71U. Each unit ships with two temperature probes on 24" of cable so you can position the main unit away from your target area. With optional probes, measurements can be made in liquids, solids, vapors, and in environments down to -40°C or -40°F.
If you need to record humidity as well, the TR-72U is your instrument. An optional temperature/humidity probe is available with 40" of cable to record remotely. Temperature and humidity data are recorded and downloaded simultaneously.
For all three inputs, you'll need our TR-73U which does everything the TR-72U does with one more input for barometric pressure. This 3-channel unit records 8,000 reading on board for each input.
Each unit includes easy to use Windows software for graphical presentation of the downloaded data, statistical viewing, exporting, all with the ability to overlay up to 8 channels on one graph. Its USB connection allows for fast data downloading.
Want more? How about downloading data without removing your units from their location? Add on our RTR-57U Handheld Data Collector and with a download cable you can dump your recorded data directly to the handheld unit for later download to the PC.
We make temperature monitoring easy and accurate.
