The OM-EL-USB-1-RCG data logger measures and stores up to 32,510 temperature readings over a -20 to 60°C (-4 to 140°F) temperature range. The 316 SS case with polycarbonate window assembly is corrosion, impact and water resistant to NEMA 4X (IP67) standards. The unit is powered by a lithium-ion rechargeable battery which allows logging for up to 1 month. The user can easily set-up the data logger and download the stored data by plugging the module straight into a PC’s USB port and running the easy-to-use Windows software. Software selectable set-up parameters include logging rate (1 sec, 10 sec, 1 min, 5 min, 30 min, 1 hr, 6 hr, 12 hr), start-date/time, and desired temperature units (ºC or ºF). Data can then be graphed, printed and exported to other applications such as Excel. Correct functioning of the unit is indicated by flashing red and green LEDs.
