Authorized Dealer

As an authorized dealer of these brands, these instruments ship genuine and factory sealed, direct from the maker, with the manufacturer documentation in the box.

The Extech MO290-NISTL is an 8-in-1 pinless moisture psychrometer with a built-in infrared thermometer, supplied with a limited NIST traceable calibration certificate. It reads moisture in wood and other building materials with virtually no surface damage, which makes it a good fit for inspection work on finished surfaces.

Beyond moisture, the meter measures humidity and air temperature through its built-in probe and reads surface temperature with a non-contact infrared design. Combining moisture, ambient and surface readings in one handheld tool cuts down on the number of instruments you carry.

The pinless sensor scans up to 0.75 inches below the surface. On-screen icons and an audible tone that speeds up as moisture rises help you sweep an area quickly and flag spots that read low, medium or high.

The limited NIST calibration certificate documents the meter's readings against traceable references, which supports quality records where verifiable measurement is part of the job.

Key Features

Eight functions in one meter

Pinless moisture, humidity, air temperature, infrared surface temperature, dew point, grains per pound and vapor pressure are all read from a single handheld tool.

Pinless moisture scanning

The sensor reads up to 0.75 inches below the surface with virtually no marks, so you can check wood and building materials without leaving pin holes.

Non-contact infrared thermometer

A built-in infrared thermometer measures surface temperature from a short standoff, useful for spotting cool areas that can signal trapped moisture.

Extech MO290-NISTL pinless moisture psychrometer and infrared thermometer with limited NIST calibration

Limited NIST calibration certificate

The meter ships with a limited NIST traceable certificate, giving you documented readings for records where verifiable measurement matters.

Fast audible and visual feedback

The tone speeds up as moisture climbs and clear icons flag low, medium or high content, so you can sweep a room and act on what you find.

Questions and Answers

Answers to the things buyers ask most

What does the limited NIST calibration certificate cover?

The meter ships with a limited NIST traceable certificate that documents its readings against traceable references. It supports quality records where verifiable measurement is required.

How deep does the pinless sensor read?

The pinless sensor scans up to 0.75 inches below the surface with virtually no marks, which makes it suitable for finished wood and building materials.

Does this meter also read humidity and temperature?

Yes. It measures relative humidity from 0 to 100% and air temperature from -20 to 170°F, plus surface temperature through its built-in infrared thermometer.

Is there an alert when moisture is high?

The meter sounds a tone that beeps faster as moisture rises and shows low, medium or high icons on the display for a quick read.
