Professional temperature logging in rough environment
UTL-3 Temperature Datalogger
UTL-3 Scientific Datalogger is a powerful miniature datalogger for professional temperature measurement and logging and is your best choice for measuring permafrost, ice, air, water and ground temperatures in rough environments.
Developed with the expert knowledge of GEOTEST and the Institute for Snow and Avalanche Research SLF in Switzerland, it is one of the most reliable and robust temperature dataloggers on the market. UTL-3 dataloggers and their predecessor models UTL-1 and UTL-2 have been deployed thousands of times for measurements in cold environments such as ice, glaciers, rock glaciers and permafrost soils and for air and water temperature measurements all over the world.
