The Tramex MRHIII moisture and humidity meter is a pocket-sized, non-destructive, digital, hand-held, electronic impendence moisture meter. Incorporating 3 modes of operation, this is the complete instrument for moisture and humidity testing. Suitable for water damage, flooring, restoration, indoor air quality, pest control, home inspection.


  • Digital, non-destructive moisture meter
  • Specific gravity adjustment for most wood species
  • Deep signal penetration up to over 1" into the materials being tested without the need to damage the surface
  • External rubber electrodes make direct contact with the material being tested for best sensitivity and repeatability
  • Wide range of readings for wood of 5% to 30% and 0 to 100 comparative for all other materials
  • Large, clear, easy to read display
  • Hold function enables user to "freeze" the reading. Useful for taking readings when the meter face is not visible
  • Switch-able "On" or "Off" when not in use
  • Automatic power cut-off switches "Off" when not in use
  • Automatic default to last user setting when switched back on
  • Battery opearated (Batteries included)

Optional: Tramex Hygro-i2 Probe & Tramex Hygro-i2 Electronic Interface Cable to suit MRHIII

The Tramex Hygro-i2® relative humidity probe is the most advanced, resilient and reusable RH probe on the market today, allowing the user to perform in situ and hood type RH testing to comply with ASTM F2170 for the ?ooring industry, and is ideal for use by Flood & Water Damage Restoration and Indoor Air Quality professionals. The speed and accuracy of the Tramex Hygro-i2® probes set them apart from all other RH probes on the market. The con?dence in knowing you are testing with the best and fastest RH probe, together with the MRHIII brings reliability and peace of mind in concrete moisture meters to a whole new level.
- Fast acclimation time
- Reusable Hygro-i2® Relative Humidity sensors prove to be the lowest cost per ASTM F2170 test
- Best in class accuracy, even at high RH >90%
- Proven robustness, durability and reliability
- Accurate, durable and best in class
- Testing per ASTM F2170, giving in situ relative humidity and ambient RH, temperature, dew point
  temperature & grains per pound
- Relative Humidity range: 0% to 100%
- Fastest Temperature response time
- Best temperature accuracy of +/-0ºC to 90 ºC
- Temperature Range: -40°C to 80°C
The Hygro-i2® probe provides measurements of relative humidity, temperature, dew point and grains per pound in structural materials such as concrete ?ooring and walls, as well as the ambient conditions within the building envelope, all shown simultaneously on one clear display.

The Hygro-i2® probes are reusable, paying for themselves after a few uses compared to single-use, disposable RH probes. Calibration checks can be carried out using the calibration check salts.
