The Tramex WDMK-X Water Damage Restoration Master Kit X is the top Tramex water damage kit, pairing both digital 5-series meters with a datalogger. It is for inspectors, surveyors and restoration technicians who test and monitor moisture content and relative humidity in concrete, timber, drywall, plaster, tile and other building materials, and need every reading recorded.

What each instrument does
MEX5 – walls and floors
Dual-depth, non-destructive testing of drywall, wood, plaster, brick, tiles, masonry, resilient flooring, laminates and roofing. The shallow setting reads to 9 mm, which helps separate a covering from its substrate, and a baseline setting compares readings against a known dry reference. With the pin probe it measures moisture content in wood and drywall, and WME in other materials. It also has its own hygrometer and infrared surface thermometer.
CMEX5 – concrete
Instant, non-destructive quantitative moisture content in concrete, using gravimetric testing as the baseline. Its bayonet port takes Hygro-i2 RH probes for in-situ testing of concrete.
Ambient and in-situ air conditions
Both meters have built-in hygrometers for ambient conditions, psychrometric values and enthalpy, and accept external RH probes for in-situ equilibrium RH readings. The Hygro-i2 probes also work with the DL-RHTX datalogger for live readings and time logs of relative humidity, temperature and dew point in rooms, materials and air spaces.
Moisture mapping
The Tramex Meters app turns readings into moisture maps, geotags results, creates and shares reports, photos and charts, and mirrors the meter screen on your phone when the meter is on the extension handle or out of sight.

How the four water damage kits compare
| Kit | Meters | Datalogger | RH probes and extras |
| WDTK – Tech Kit | ME5 + CME5 | No | Extension handle only |
| WDIK – Inspector Kit | CMEX5 + ME5 | DL-RHTX | Pin probe, 200 mm insulated pins, 127 mm short narrow RH probe, IR thermometer, salts, handle |
| WDMK – Master Kit | CMEX5 + ME5 | DL-RHTX | As WDIK, but with the 260 mm narrow wand RH probe, plus one Hygro-i2 probe and hole liners |
| WDMK-X – Master Kit X | CMEX5 + MEX5 | DL-RHTX | As WDMK |
The practical differences: the WDTK is the analogue pair with no logging. The WDIK adds the digital CMEX5, a datalogger, pin probe and RH wand. The WDMK adds a Hygro-i2 in-situ probe and hole liners and swaps to the longer RH wand. The WDMK-X swaps the analogue ME5 for the digital MEX5, so both meters carry hygrometers, surface thermometers and probe ports – the one to choose when the record matters more than the price.

Frequently asked questions
Is buying the kit cheaper than the parts?
Generally yes, and it removes the risk of ordering an accessory with the wrong connector. Every component is also sold individually if you would rather build up over time.
What connector do the accessories use?
The CMEX5, MEX5 and DL-RHTX all use the bayonet connector, so any probes added later must be the “B” suffix versions. The AP-F2170-B accessory pack is the matching in-situ RH kit.
Can I run a full ASTM F2170 slab test with this kit?
Not on its own. The kit includes one Hygro-i2 probe and hole liners, but ASTM F2170 calls for three test locations for the first 100 m² and one more for each additional 100 m². Add Hygro-i2 probes, or the AP-F2170-B pack.
Is the Hygro-i2 interface cable included?
Tramex's kit data sheet does not list the RHIE2B interface cable that connects a Hygro-i2 probe to the meters or the DL-RHTX. Ask us to confirm before you order if you need it.
Is a phone included?
No. The Tramex Meters app is a free download for iOS and Android and runs on your own device.
