## Overview

The Extech MO290 is a versatile 8-in-1 pinless moisture psychrometer featuring a non-contact infrared thermometer with an 8:1 distance-to-spot ratio and 0.75-inch pinless measurement depth. It offers programmable moisture and humidity alarms, a large backlit dual display, and includes a remote pin-type probe for contact readings. Designed for professionals seeking reliable, precise moisture and environmental data in one compact tool.

## Description

The MO290 is an 8-in-1 meter that combines a Pin/Pinless Moisture Meter with a built-in InfraRed Thermometer. Additional measurements include: Temperature, Humidity, Grains per Pound, Dew Point, Vapor Pressure, and Condensation Point. Complete with pin moisture probe, 9-Volt battery, and case.

Review: Reliable and just works well - I don’t like the on/off button as it easily gets bumped and will turn on when you don’t want to. The depth on the pinless mode seems really good. I like that I can set it down on a flat surface and then back up and take a picture without having to hold onto it like I do with protimeter. Unit has been durable and reliable. It would be nice if they added an accessory jack. Overall good value. I’ve bought several now.
Review: The Extech MO55: A Moisture Detective’s Best Friend – D & D Approved! 🔍💧✅ - If Sherlock Holmes were a home inspector, he’d carry the Extech MO55 in his pocket like a magnifying glass for moisture mysteries! This little gadget is like a truth serum for damp drywall, stubborn subfloors, and sneaky wooden beams that think they can hide moisture from us. Think again, fellas! As a backup for D & D Home Inspection Services, the MO55 has been a rockstar—quick, reliable, and precise! Whether we’re using the pin mode for those deep investigations or the pinless mode for a less invasive check, it delivers the facts fast. The audible alert is an absolute bonus—it basically shouts, 'Hey! Something’s fishy here!' (or should I say… damp?). Lightweight, easy to use, and built to handle the rough-and-tumble world of home inspections, this meter has already proven its worth. If moisture had a lawyer, it would hate this device. Highly recommend for pros and homeowners alike—D & D gives it a solid ✅!

### ⭐⭐⭐⭐⭐ Here’s the perfect case
*by C***R on December 11, 2025*

It’s small and fits perfectly inside a “GLCON Vertical-Stripe Hard Drive Case for Western Digital WD Elements My Passport/Samsung T9 Portable/Seagate Portable 1TB 2TB 4TB - Shockproof External Hard Drive Travel Carrying Case” Currently the brown striped case (which looks like a piece of wood) is $7. You’re welcome. I’ll review the device later.
