Extech MO57 Pinless Moisture Meter
The Extech MO57 Pinless Moisture Meter gives fast moisture checks without marking or damaging the surface. It uses a pinless spherical sensor that glides smoothly across wood and building materials. This makes it ideal for inspections where the finish must remain untouched.
Moisture can hide behind walls, under tiles and beneath carpets, so accurate testing is important. The Extech MO57 Pinless Moisture Meter measures to a depth of up to 100mm and provides readings for wood and other building materials. Audible and visual indicators help you identify damp areas quickly.
Designed for Building Surveys
Because the meter does not require pins, it is suitable for restoration work and water damage inspections. Users can scan plaster, concrete, mortar and other surfaces with ease. The compact body also makes it simple to carry between jobs.
Display icons show low, medium and high moisture levels at a glance. In addition, the data hold function freezes the reading on screen when access is difficult. The built-in verification test also helps confirm correct operation before measurements begin.
Simple and Reliable Operation
The Extech MO57 Pinless Moisture Meter includes an auto power off function to help preserve battery life during long inspections. Its rounded sensor allows measurements on uneven and non-flat surfaces where standard meters may struggle. A wrist strap and compact size improve handling during routine testing.
Two different set types are available, allowing users to choose the package that best suits their application requirements. Whether checking for leaks, carrying out restoration work or surveying building materials, the Extech MO57 Pinless Moisture Meter delivers reliable and non-destructive moisture measurement.
