Top-10 Moisture Meters
Loved in the USA

The Protimeter SurveyMaster Dual-Function Moisture Meter is a versatile tool designed for professionals and serious DIYers who need reliable moisture readings in various building materials like wood, drywall, and concrete. It offers two measurement modes: pin mode for direct contact measurements and non-invasive mode for surface scanning, making it adaptable for different tasks. Its accuracy is maintained through automatic calibration and firmware updates, helping ensure consistent results over time. The larger, easy-to-read display improves usability on site, and the long battery life means fewer interruptions during work.

Bluetooth connectivity is a standout feature, allowing users to save and track readings easily through a mobile app, which is especially handy for keeping records. Customizable settings like auto shut-off, backlight, and buzzer add to user convenience. In terms of build, it is reasonably compact and lightweight at just over a pound, with a durable case included to protect the device. One consideration is that it requires alkaline batteries, which may need replacement more often compared to rechargeable options.

If you need a moisture meter that combines thorough measurement capabilities with smart features and easy data management, this model is a strong candidate.

The Extech MO290 is a versatile moisture meter that combines pinless and pin-type measurement methods, making it suitable for both surface and deeper moisture checks. Its pinless sensor can measure moisture up to 0.75 inches below the surface, which is helpful for checking wood, drywall, or other materials without causing damage. The included remote pin probe adds flexibility for direct contact readings and is connected by a 3-foot cable for convenience.

It features a large, backlit dual display that clearly shows both moisture and temperature readings, improving readability in various lighting conditions. Another useful feature is the built-in infrared thermometer with an 8:1 distance-to-spot ratio, allowing non-contact temperature measurement which helps identify areas at risk of condensation through automatic differential temperature calculations. The product also offers programmable high and low alarms, aiding users in quickly spotting problem areas.

The meter is lightweight and compact, powered by standard AA batteries, which are included, making it easy to carry and use in the field. This meter is well-suited for homeowners, contractors, or inspectors who want a reliable, multi-function tool for general moisture and temperature checks rather than specialized industrial use.

The Wagner Meters Rapid RH L6 Smart Sensors are designed primarily for measuring concrete moisture using the ASTM F2170 standard. This product consists of 50 refill sensors meant to be used with the Rapid RH L6 Starter Kit (sold separately), making it a good choice for contractors or professionals who frequently test concrete moisture over large areas. The sensors measure relative humidity deep within concrete slabs, which is important for accurate moisture assessment before flooring installation. These sensors offer improved responsiveness, especially in high humidity conditions, and support both Fahrenheit and Celsius readings for flexibility. They feature integrated data storage, which helps keep track of test results without extra effort.

One of the key benefits is the straightforward and cost-effective testing process, simplifying what is usually a complicated procedure. The package includes useful accessories like extensions, protective caps, stainless steel covers, and a calibration certificate, pointing to thoughtful build quality and attention to durability. The sensors do not require batteries, reducing maintenance concerns.

Since these are refill sensors, you must already have the Rapid RH L6 Reader device, which is sold separately, so this product alone won’t work out of the box. Its measurement range and accuracy are excellent for concrete moisture testing but not suited for general-purpose moisture measurement in wood or other materials. These sensors focus on relative humidity inside concrete rather than surface moisture, making them ideal for a specific niche. For professionals requiring reliable and standardized concrete moisture testing with minimal hassle and accurate deep readings, this sensor pack is a practical and durable choice, while other meters might be better suited for casual or multi-material moisture measuring.
