The Extech TH30 is a USB dual temperature datalogger that records two channels — T1 (air temperature) measured by a built-in NTC thermistor and T2 (external probe temperature) measured by the included TP830 probe — each reading captured with a date/time stamp. It is built in a compact, rugged housing with a standard USB connector and a large 5-digit LCD, and a smart LED provides a color-coded indication of temperature reading status.

The TH30 is designed to record temperature over time and then transfer the stored data to a PC. When plugged into a computer after datalogging is completed, it generates a PDF report or an Excel spreadsheet containing the logged data and a trending graph, making it straightforward to archive and review temperature history. An 8-location bookmark function lets the user mark points of interest in a recording log with a press of the Mark button.

ValueTronics stocks and holds its own inventory in a 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Holding our own stock lets us match the right instrument and condition to your application and ship it directly.
