Onset Hobo UX120 thermocouple logger

The Onset Hobo UX120 thermocouple logger is a 4-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 1820°C) and can accept up to four J, K, T, E, R, S, B, or N type probes. This flexibility enables the logger to be used in a range of monitoring projects. For example, food quality assurance managers can use the 4-channel thermocouple loggers to profile oven temperatures at various points to ensure product quality.

In addition to accepting four thermocouple sensors, the logger features an internal temperature sensor for logging ambient temperatures, further extending the range of application possibilities.

The logger features an easy-to-view LCD that visually confirms logger operation and battery status, eliminating the need to connect the logger to a computer to view the information. As the logger records temperatures, the LCD refreshes every 15 seconds to provide a near real-time readout of current temperatures as well as 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.

The logger also features a large memory capacity capable of storing 1.9 million measurements. This enables the loggers to be deployed for longer periods between offloads.  Firmware is user upgradeable, and the logger offers start, stop and restart push-buttons to make installation fast and easy.
