The Moisture and Relative Humidity MRH III is a hand-held digital moisture meter
calibrated for most building materials. It also incorporates optional plug-in heavy-duty
pin-type wood probes and Hygro-i ® probes for measurement of relative humidity and
ambient conditions and allowing for testing of concrete per international standards BS
8201, 8203, 5325 and ASTM F2170, F2420 (with optional sleeves or hood). Suitable for
many industries including Flooring, Water Damage Restoration, Indoor Air Quality, Home
Inspection and Pest Control.

FEATURES

• Deep signal, non-destructive penetration up to 30 mm
• (11⁄4") in wood and drywall in non-destructive mode.
• Detects moisture through paint, wall coverings, drywall,
• ceramic tiles, floor coverings, wood, roof coverings and
• most building materials.
• Hold function “freezes” meter reading when inspecting
• areas where the meter face is not visible.
• Audio signal sounds when meter indicates high readings.
• Large clear backlit digital display giving meaningful
• readings.
• Accuracy in very low moisture content readings and up
• to 55% moisture content readings in wood in non-invasive
• mode.
• Attachable pin-type wood probe for invasive testing
• (optional).
• Adjustment of specific gravity for wood species correction.
• Attaches to a reusable relative humidity Hygro-i ® probe
• for in situ or hood testing of concrete per international
• standards BS 8201, 8203, 5325 and ASTM F2170, F2420.
• (optional)
• Attachable Hygro-i ® Relative Humidity probe for
• relative humidity, temperature, dew point and grams per
• kilo readings all shown on one clear display (optional).
