TSI 800220 Telescopic Temperature and Humidity Probe

The TSI Alnor Temperature and Humidity Probe can be inserted into a 5/16 inch hole to measure relative humidity and temperature as well as calculate wet bulb temperature and dew point. The telescopic probe extends from 9 to 39 in (23 to 99 cm) so it can measure ducts of varying sizes.

Telescopic temperature and humidity probe extends from 9 to 39 inches (230 to 990 mm) and is ideal for measuring inside of duct work before and after a coil. Probe can be inserted into a standard 5/16 in. (8 mm) diameter hole typically used for pitot traverses and can be used to calculate wet bulb and dewpoint temperatures.
