The Extech SD500 is a humidity/temperature datalogger that measures and records relative humidity and ambient temperature at the same time. A dual LCD shows both readings together, while the internal datalogger date- and time-stamps each measurement and writes it to an SD card in Excel format for transfer to a PC.
The SD500 is intended to monitor and record temperature and humidity values in calibration rooms, offices, clean rooms, and storage facilities. Its selectable sampling intervals let it track conditions over time rather than capture only single readings.
ValueTronics stocks and holds its own inventory in a 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois.
Extech Instruments became part of FLIR Systems in 2007, and FLIR Systems in turn joined Teledyne Technologies in 2021. The Extech brand has continued under each of these ownership changes.
