Tramex Building Survey Inspection EZ Kit – Portable Moisture & Humidity Meter
Ideal for Quickly Detecting Moisture in Buildings and Materials
The Tramex BSIZK is a handheld, non-invasive kit for measuring moisture and humidity in drywall, wood, plaster, brick, ceramic tiles, laminates, roofing, and other construction materials. It helps identify hidden damp conditions that can lead to mold, microbial growth, or wood damage.
Comprehensive Moisture Detection
Hidden moisture behind walls or under flooring can go unnoticed without proper tools. The Tramex digital MRH III, paired with the reusable Ambient Relative Humidity Hygro-i2 Short Probe, measures relative humidity, temperature, and dew point to pinpoint moisture issues. Once identified, appropriate remedial actions can improve building health.
Accurate Probing for Wood and Concrete
The heavy-duty pin probes measure wood moisture with insulated 7.8" pins for deep wall cavity access. Concrete slab relative humidity can be tested using the reusable RH probe with included hole liners. The kit is stored in a durable Tramex Easy-travel case for portability.
Features of MRH III:
- Non-destructive signal penetration up to 30mm in wood and drywall.
- Measures moisture through paint, wall coverings, tiles, floor coverings, wood, and most building materials.
- Hold function freezes readings when the meter face isn’t visible.
- Audio alarm signals high moisture readings.
- Backlit digital display for easy, meaningful readings.
- Accurate non-invasive moisture content readings from 5–55% in wood.
- Attachable pin probe for hard-to-reach areas and wall cavity testing.
- Attachable RH probe for in situ or hood testing of concrete, measuring relative humidity, temperature, dew point, and grains per pound.

To broaden your professional inspection toolkit
For comprehensive moisture surveying of walls, floors, ceilings and a variety of building materials, consider additional instruments that support deeper and more flexible site analysis. The Tramex Building Survey Inspection Kit expands capability with both non‑destructive and pin‑type moisture probes plus relative humidity measurement for more detailed building envelope diagnostics. For applications requiring deeper scanning of roofing and wall substrates, the Tramex Roof & Wall Scanner delivers versatile non‑destructive moisture detection and leak tracing performance in complex structural materials. Additionally, the Tramex Roofing Master Kit provides a comprehensive suite of tools including roof‑specific scanners and probes for advanced moisture surveying, leak tracing and insulation evaluation on flat roof systems and waterproofing assemblies.
