New four-channel thermocouple logger streamlines temperature monitoring applications.

Onset Computer Corp. recently released the Hobo UX120 thermocouple logger, a four-channel LCD data logger for measuring and recording temperature in a broad range of monitoring applications.

Starting at $275, the compact thermocouple logger offers a deployment-friendly LCD display and flexible support for a variety of plug-in thermocouple probes. The new logger records temperatures over a broad range (-260⁰ to 1820⁰ 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 will use the four-channel thermocouple loggers to profile oven temperatures at various points to ensure product quality. Civil engineers will use the loggers to document concrete temperatures at multiple depths during the curing process. And, research scientists will use the loggers in a range of projects, from wildfire ecology research to bird nesting studies.

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 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 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 pushbuttons.
