Description
The HOBO UX120 Thermocouple Logger is a four-channel LCD data logger for measuring and recording temperature in a broad range of monitoring applications. The 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 logger features an internal temperature sensor for logging ambient temperatures, further extending the range of application possibilities
