A Home Inspectors Guide To The Most Recommended Moisture Meter Device!

A frequent request on many home inspector message boards is “What is the best moisture meter”. Like any other tool, software, or whatever you are looking for, you will get many different answers from that question from your colleagues. We have spent the time and went through most of the home inspector message boards to do the work for you. You can use this as a starting point in evaluating moisture meters, but still do your own research.

There are many moisture meters to evaluate, at all different price points. If you do a survey from home inspectors, you will see the same moisture meter brands come up over and over again. If you happen to need a refresher of why using a moisture meter is necessary during a home inspection you can start here.

When choosing a device, it’s important to consider the following.

  • The accuracy of the moisture meter.
  • The speed of the moisture meter.
  • Ease of use.
  • Versatility of device (how many building materials can it test)

This blog will focus on what other home inspectors are using and recommending for their daily inspections. We do not endorse any of these devices, nor have we done any product testing or evaluations of these moisture meters.

Below are the most recommended and trusted devices by home inspectors.

    This is the never ending question??? I’m in school now and want to get something reliable now. Also don’t want to spend the $630 for the protimeter. I tried the AccMaster pin & pinless and returned it because it wasn’t accurate. Right now I’m between these
    1. General MMH800 4 in 1 – $90
    2. Extech MO55 both pin $ pinless
    Or buying both of these
    Klein ET140 pinless – $39
    General pins MMDE4 – $34

      Don’t get the General MMH800 4 in 1 It’s not accurate either, I have tried a couple cheaper alternatives and went to the protimeter and it’s worth every penny, when it comes to moisture meters there is no other comparative option for reliability and accuracy.
