Temperature, RH Probe from GrayWolf

GrayWolf Sensing Solutions

The RH-AS2 probe from GrayWolf Sensing Solutions, Shelton, CT, works with the company's rugged, handheld AdvancedSense HVAC/OH/FM/IAQ meters to measure RH, dew point, absolute and specific humidity, and wet- and dry-bulb temperatures. The probe is 14 mm dia. by 40 mm long and can be directly connected to the AdvancedSense or to an ACC-RH-HDLA handle for handheld use and insertion into ducts. Humidity range is 0%–100% RH noncondensing with ±2% RH accuracy. The probe, when connected to a meter outfitted with a BP-101 barometric pressure sensor, lets the meter provide pressure-compensated moisture readings. You can also use the probe in conjunction with other probes.
