Answer This Question
A:Â If slabs is referring to concrete, then no. This unit is not able to detect moisture in concrete as the material interferes with the sensor due to its conductivity.

Very satisfied with the performance however it’s difficult to read the screen you have to look at it at a 45° angle. Planning on taking it back to have it replaced. Would buy again

This is a less expensive version of the meter I had originally wanted. That said this meter performed very well. I am an RV Inspector so the non-invasive meter was essential. It works well on all interior surfaces of the unit and allows me to give my customers a better indication of condition.

4 star
Great meter for the price. Has everything a $500 flir or extech meter would have. I bought 5 of these for my techs reason for 4 stars was because on 2 of the sets the prongs on the attachment were not pointed but instead hooked at the ends and when the first time i used it of course had to be on looped pile carpet and it hooks and pulls the loops coming back out of the carpet. Will have to file the tips down but shouldnt have to do so. Otherwise great product.

General Tools & Instruments RHMG650
Super unit! Inexpensive and reliable.
Readings are dead on!
Used multiple readers on one job site this little unit was more accurate than the rest!
Going to purchase another 12 for the rest of my techs.
Recommended by a field adjuster and a home inspector.
For the price why not?
