For environmental recording of temperature and humidity with an easy to read digital display, and a connection directly to your network, try our new TR-71W and TR72W. These feature-packed units will even send you an email if your pre-set temperature limits have been exceeded. That means if your $2M inventory of beef starts to thaw, you'll get an email sent immediately to your cell phone so you can hurry in and correct the problem.
With our recording software, you can view data right from your browser and monitor temperature, humidity, start times, and access features like downloading data, and checking the battery back-up. These lightweight instruments also include a dual 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-71W. 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 °F.
If you need to record humidity as well, the TR-72W 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.
Install a network ready recorder today and quit worrying about your applications while you're out of the office.

*1 Compatible with all T&D tested and approved models.
*2 Errors in accuracy increase with increase in electrical noise.
*3 Battery Life varies according to type of battery, measuring environment , communication frequency , and ambient temperature. This estimate of battery life was based on normal use under normal conditions using a new battery. This is in no way a guarantee of battery life.
*4 Without protrusion.
*5 The backup battery is for data backup and emergency use only. The battery is not used under normal conditions. If using only the battery, network communication cannot occur.
*6 This is the working environment specs when using only the data logger. When using with a LAN card or cell phone these specs may vary.
