Onset has added to its line of external sensors with the addition of the TMC6-HE air-temperature sensor. The sensor is ideal for a range of monitoring applications from monitoring the efficiency of solar thermal systems to tracking building energy use. According to company officials, the sensor’s copper-plated probe ensures high-accuracy measurements and faster response time than previous models. The sensor can be attached to water pipes, hot water storage tanks and boilers. It is compatible with a number of Onset data loggers, which use Onset Hoboware to graph and analyze findings on a personal computer.
