Onset has introduced the new TMC6-HE air temperature sensor, the latest addition to the company’s line of external sensors for energy and environmental monitoring. Ideal for a range of energy monitoring applications — from monitoring the efficiency of solar thermal systems to tracking building energy use — the sensor’s copper-plated probe ensures high-accuracy measurements and faster response time than previous models. The sensor can be easily attached to water pipes, hot water storage tanks, or boilers and is compatible with a number of Onset HOBO U12 USB data loggers. For plotting and analyzing temperature data, Onset offers HOBOware® software, an intuitive graphing and analysis software package for PC and Mac computers.
