The HOBO UX120 Thermocouple Data Logger is a four-channel LCD data logger for measuring and recording temperature in a broad range of monitoring applications. The data logger makes it easy and convenient to record temperatures over a broad range (-260 to 1820⁰ C) and can accept up to four J, K, T, E, R, S, B, or N type probes.
In addition to accepting four thermocouple probes, the data logger features an internal temperature sensor for logging ambient temperatures, further extending the range of application possibilities.
Onset also offers a single-channel thermocouple data logger, the HOBO UX100-014M.
