4 Best Extech Moisture Meters 2025 in the United States

The Extech MO290 is a versatile moisture meter that offers both pinless and pin-type measurement options, making it suitable for a variety of materials and surfaces. One key strength is its ability to measure moisture up to 0.75 inches below the surface without pins, reducing surface damage. Additionally, the included pin-type probe with a 3-foot cable allows for precise contact readings, which can be useful in more detailed inspections.

The programmable high/low moisture and humidity alarms are a convenient feature for monitoring and ensuring optimal conditions in various environments. The device also includes a non-contact infrared thermometer, which can measure temperature from a distance and helps in identifying potential condensation points, adding to its functionality. Users will appreciate the large, easy-to-read dual display, which is backlit for use in low-light conditions, enhancing readability.

On the downside, the device might be a bit more complex for beginners due to its multiple features and settings. Additionally, while the pinless measurement depth is sufficient for many applications, it may not be adequate for deeper materials. The device is relatively lightweight and portable, making it easy to handle during inspections. With its comprehensive feature set, the Extech MO290 is best suited for professionals in construction, home inspection, and HVAC who require precise and versatile moisture measurement tools.

The Extech MO750 Soil Moisture Meter is designed to measure soil moisture content from 0 to 50%, making it suitable for gardening and farming applications. One of its strengths is its easy one-hand operation, which simplifies usage, especially when you’re working in the garden. The device also records min and max moisture readings, helping you keep track of changing soil conditions over time.

Another useful feature is the data hold function that allows you to freeze readings on display, which can be handy for recording purposes. The water-resistant housing is beneficial for outdoor use, ensuring durability in various weather conditions. On the downside, this moisture meter is ranked #508 in soil meters, indicating it might not be the most popular or cutting-edge choice in the market. Weighing 0.27 kilograms, it is relatively lightweight, but the bulky dimensions (1.6 x 1.6 x 14.7 inches) might not be ideal for compact storage.

It includes four AAA batteries, which are convenient but might require frequent replacements depending on usage. Additionally, the measurement range is limited to soil moisture content and does not support pinless operation, which could restrict its application in different materials or deeper measurements. The display is straightforward but may not offer advanced readability features like backlighting for low-light conditions. This soil moisture meter is best suited for hobbyist gardeners or small-scale farmers who need an easy-to-use tool for monitoring soil moisture levels effectively.
