Best Moisture Meters of 2025

"I was thrilled to discover how intuitive this moisture reader is. I knew nothing about flooring or moisture, but it was simple to operate—just a single button for material type, then place it down and it reads automatically. It's been consistent and accurate, helping me monitor moisture levels effectively as I work on my flooded laundry room."

"Using this meter has been a game-changer for identifying leaks in my home's walls. The display is easy to read, making it accessible even for someone like me who is not an expert. It's been a great aid in finding those elusive pinholes in water lines."

"I bought this meter for measuring wood moisture in my woodworking projects, and it does exactly what it promises. The two settings for softwood and hardwood are handy, and I appreciate the prompt and knowledgeable customer service from General Tools. They helped me understand the calibration for different wood species."

"I really like this product. It's durable and has a great sensor for detecting leaks and moisture. I found it easy to transfer pictures to my iPhone via Bluetooth, despite some concerns from other reviews. I just wait a moment for the images to show up in the app before sharing."

"I bought this unit in October and while I haven't used it as much as expected, it has been quite handy. My customers appreciate being able to see what I'm looking for before we open walls. However, the pinned mode has its limitations, reading zero below 7% moisture, which forces me to guess."

"I was disappointed with this product. It didn't work as advertised, providing inaccurate readings. After contacting customer support, I learned that the device was likely defective. I expected better from FLIR, especially at this price point."

"I worked in pest control for four years and used this meter during countless inspections. It has proven to be incredibly durable and provides accurate moisture readings. While it may not offer the extensive data of other models, it does exactly what I need it to do."

"This tool has been invaluable for measuring the moisture content of firewood. It has saved me from burning wood that was too wet, ensuring a better fire every time."

"I bought this to check the moisture level on a fence before staining it, and it worked perfectly. Although there were no instructions included, I quickly found a tutorial online that made it easy to use."

"I’ve been looking for moisture meters for a while, and this one is definitely the easiest to operate; just press it against the concrete, and I get my reading instantly."

"This tool is fantastic for taking multiple readings quickly. While it may not be the cheapest option, it’s a precision device, and the results can influence significant decisions, which makes it worth the investment."

"It’s reassuring to know that the readings I get are accurate and not just educated guesses."

"I found it incredibly easy to use, and it helped me confirm a leak in my dining room. After struggling to find this item locally, I ordered it from Amazon and received it the next day!"

"This tool is a game-changer for detecting moisture non-destructively. I was able to identify and address potential mold issues before they escalated, and its accuracy was impressive."

"I was dealing with a musky smell from my wall, and using this meter helped me pinpoint where to cut for repairs. After replacing insulation and using a dehumidifier, the smell is completely gone!"

"I found this tool to be incredibly useful. While I haven't used it extensively, it appears quite accurate compared to my existing moisture meter. The temperature and humidity gauge is particularly beneficial for diagnosing moisture issues. However, I noticed it takes some time to acclimate to indoor conditions. I wanted a non-invasive option to avoid damaging surfaces, and while it works decently, it performs better with pins. Overall, for the price, I feel this is a good meter."

"As a general contractor, I sometimes need to check moisture in homes. This is my second General Tool moisture meter, and the MMH800 is a step up, offering more functions including temperature readings. I was on-site with a mold remediation technician and compared my readings with his professional meter. I found minimal differences in our readings, which is impressive. My favorite aspect of the MMH800 is its affordability and accuracy, enhancing my ability to serve clients better."

"I purchased this meter to monitor moisture content in my prefinished hardwood floors. While the flooring was well dried, the meter bottoms out at 5%, giving no readings at that level. It worked reliably on other materials like plywood and pine. I also tried it on some outdoor-stored oak and walnut, and it yielded readings of 12-15%. So, while it performs well, keep in mind it may not work as effectively at the very dry end of its range."

“As a public insurance adjuster, I evaluate properties daily for water intrusion. After much deliberation, I decided on this dual-function meter, and I have no regrets. Unlike cheaper alternatives, I don’t have to switch settings; it reads all materials and penetrates 3/4" below the surface. I've successfully detected moisture behind ceramic tiles, which was impossible with less expensive meters. The pin feature is also excellent. I highly recommend it!”

“I’ve been using this moisture meter daily as a home inspector, and it’s the best meter I’ve ever owned. It’s incredibly user-friendly and precise. If you’re in the market for a moisture meter, this is the one!”

“I waited to review this product until I had used it extensively. The quality is impressive and user-friendly. The long probes are perfect for checking deep within walls, helping me address situations where clients insisted their concrete slabs were dry. I was able to prove otherwise. This investment has already paid off!”

"I use this every single day while performing home inspections. It’s probably my favorite tool. The problems I’ve uncovered and the knowledge I’ve provided have made this tool worth it many times over. The pin and pinless modes are essential. Without the pinless mode, I wouldn’t know if there is still leaking after a few dry days. The results are highly reproducible and accurate. I appreciate the moisture level chart on the back, as it helps differentiate between readings."

"I've found this moisture meter to be incredibly effective. It easily identifies moisture in both carpet and walls, even in hard-to-reach areas. I avoid keeping it in my vehicle, though, as I think it might damage the display. Overall, it’s a fantastic product that I rely on for most of my jobs."

"After using this meter for three months, I noticed it consistently showed higher moisture levels than a known dry hardwood piece. Unfortunately, it was too late to return, and I ended up tossing it out. I now use a cheaper alternative that provides more realistic readings. It's disappointing, as I had high hopes for this product."

"I find this tool awesome for my work, especially for home inspections. It’s simple, effective, and has a solid case that protects it in my tool bag."

"As a home inspector, I’ve relied on this meter for years. It’s trustable and worth every penny."

"This new version has proven to be a high-tech upgrade from the old one I've used for decades. I expect it to last just as long."

"After a fire in my apartment, I needed to assess moisture in the walls. This professional-grade tool impressed the remediation expert, who said it matched his equipment. Well-built with a decent warranty, it reliably performed the tasks I needed. Initially, I found it confusing, but after revisiting the manual, I discovered its thermal camera and external pin probe attachment. I highly recommend taking time to read the manual for the best results!"

"I purchased the MR77 and have been using it daily. It's super easy to use, with excellent backlighting. While I mainly use the non-penetrating feature, having the penetrating pins included is a great bonus. I’m very satisfied with my purchase!"

"I bought this meter and was impressed by its accuracy and ease of use. Although I have other units, this one stands out. However, it requires some self-guidance to fully grasp all its features. Overall, a solid tool!"
