Click here for PDF version

A new probe is available for GrayWolf’s rugged, hand-held AdvancedSense HVAC/OH/FM/IAQ meters. The RH-AS2 probe is capable of measuring:

  • Relative Humidity
  • Dewpoint
  • Absolute Humidity
  • Specific Humidity
  • Wetbulb Temperature
  • Drybulb Temperature

This small diameter (14 mm, 0.6 inch Ø, 40mm, 1.6 inch L) probe may be directly connected to the AdvancedSense via the lower left 7 pin socket. It may alternatively be connected to an ACC-RH-HDLA (100mm, 4 inch L) handle with 1m cable for hand-held use and easy insertion into ducts. Humidity range is 0 to 100%RH (non-condensing) with accuracy of +/-2%RH. When connected to an AdvancedSense meter that is outfitted with the optional BP-101 barometric pressure sensor, relevant moisture readings are auto-compensated for pressure changes due to altitude, meteorology, etc. The RH-AS2 may be used in conjunction with other probes for parameters including Differential Pressure, Air Velocity, Volume Flow, Carbon Dioxide, Carbon Monoxide, VOCs, Formaldehyde, Surface Temperature and many others. The AdvancedSense, with a color touch-screen, also enables powerful features such as audio, photo and text note attachment to data-logged files, on-board video help and much, much more.
