Dual-function moisture meter with large backlit display

Code LMT219
Weight (kg) .225

  • This reliable moisture meter has two modes of operation, search and measure.
  • These functions can help the user to distinguish sub-surface from surface moisture, essential information when trying to establish the extent and cause of a dampness problem.
  • It is a versatile pin and non-invasive meter, ergonomically designed for easy, one-handed operation to measure moisture in buildings and other related structures both on and below the surface.
  • This allows you to assess moisture levels for new or refurbishing activities and diagnose moisture-related problems in existing buildings.

LMT219 Surveymaster Instrument supplied complete with;

  • Soft Pouch
  • HD MC Probe
  • Deep Wall Probes 5″ (127mm)
  • Pin Calibration Check
  • Instructions
  • Wood Calibration Chart


  • Rugged construction
  • Large backlit display
  • Pin moisture measurement
  • Non-invasive measurement up to ¾” (20mm) below the surface
  • Wide range of accessory plugins
  • Industry leading 2-year warranty

User adjustable features:

  • Auto shut off 1-6 mins.
  • Hold feature
  • Backlight on/off.
  • Audible on/off.
  • Dry, At Risk and Wet Indicator on/off.


  • Easy-to-use
  • Allows rapid assessment of building moisture
  • Instant readings in a wide range of building materials
  • Non-invasive measurement not adversely affected by surface moisture
  • Two meters in one

Search Mode: Non-Invasive:

  • The search mode is used to assess the moisture level beneath the surface of solid walls and floors independently of surface conditions.
  • The nominal depth of the measurement is ¾ inch (19 mm); this depends on the density and other characteristics of the material being measured.
  • When held against the surface, as shown below, the instrument transmits a signal into the material.
  • The relative moisture level is shown on the digital display and its moisture condition is shown on the accompanying scale of colour-coded lights.
This measurement presentation helps the user to:
  • Look for moisture behind wall and floor coverings, such as tile and vinyl.
  • Assess, in relative terms, if the material is in a dry, borderline or damp condition.
  • Map the extent of the problem numerically.
  • Non-invasive pinless radio frequency finds moisture at depth where moisture is not always directly visible—up to 3/4 in (25.4 mm) below the surface.
  • This mode of measurement is not adversely affected by the presence of surface moisture.

Note: Metal additives in concrete can create false positive readings.

Measure Mode: Pin-Type

  • This mode is used to measure the moisture level at the surface and at incremental depth, when used with the auxiliary probes.
  • Measure mode readings are precise and specific to the immediate area of contact of the electrodes.
  • The actual moisture content of wood is shown on the digital display with the corresponding moisture condition shown on the accompanying scale of colour-coded lights.
  • Wood Moisture Equivalent (WME) values are shown for other non-conductive, porous building materials.
  • Pin-type probes measure moisture in wood and other building materials (use provided wood species calibration chart for more precise readings)
  • Deep wall probes establish the presence of moisture in wall cavity insulation, sub and surface structures

Reference mode (Patent Pending):

  • In both Pin and Search mode, the Reference Mode can be used.
  • Reference mode can be useful when trying to establish what materials are above or below a point of reference or dry standard.
  • Measure the dry standard or baseline material until the meter’s reading is stable then press for seconds.
  • This will store the reading until the mode changes of the meter turns off.
  • Now all readings taken after will be displayed as normal, but below you will see a second reading that shows you if the material is measured above or below the original reading.
