Product Information

The Tramex Relative Humidity Probes are the most advanced, resilient, and re-usable RH probe on the market today, allowing the user to evaluate moisture conditions within the building structure. The different lengths and thicknesses make them ideal for use for Flood and Water Damage Restoration as well as Building  Survey professionals. The probes, which house the latest Hygro-i2 technology, measure relative humidity, temperature, dewpoint temperature, and grains per pound humidity ratio. The probes can be used for the evaluation of moisture conditions of wall and cavity structures as well as ambient air conditions within the building envelope. The speed and accuracy of the Tramex Hygro-i2® probes set them apart from all other RH probes. The confidence in knowing you are testing with the best and fastest RH probe brings reliability and peace of mind to a whole new level.


Used in conjunction with the Tramex CMEX5, Feedback Datalogger DL-RHTX, CMEX II, or the Tramex MRH III non-destructive moisture meters, the probes provides measurements of relative humidity, temperature, dew point, and grains per pound in structural materials such as concrete flooring and walls, as well as the ambient conditions within the building envelope, all shown simultaneously on one clear display. The probes are reusable and calibration checks can be carried out using the calibration check salts.
