Onset Computer Corp. HOBO UX120 Thermocouple Logger is a four-channel, LCD data logger for measuring and recording temperature between -260 to 1820C and can accept up to four J, K, T, E, R, S, B or N probes. The logger features an internal temperature sensor for logging temperatures, a memory capable of storing 1.9 million measurements, upgradeable firm wear and start, stop and restart pushbuttons. Confirming logger operation and battery status, the LCD screen refreshes every 15 seconds to provide a near real-time readout as well as a minimum, maximum, average and standard deviation statistics. On-screen alarms can be set for each temperature channel to notify users if temperatures exceed high or low thresholds.
