The inclusion of essential functions like hold, low battery indicator, and auto-power off enhances the usability of the device and helps preserve battery life.

It is important to note that the Klein ET140 is calibrated specifically for drywall, masonry, hardwood, and softwood, which means it may not give accurate readings on other materials. This limits its versatility compared to some competitors that can handle a wider variety of surfaces. Moreover, while it has a decent build quality with 2m drop protection, it might not withstand extremely rough use, so care should be taken during operation.

For those focused on moisture detection in the specified materials, the Klein Tools ET140 is an effective and user-friendly option that offers good performance and clear readings. If you're looking for a moisture meter that can be used on a broader range of materials or in harsher environments, you might need to explore other models.

Durability and Build Quality

Most important from
108 reviews

Accuracy
Delivers consistent and reliable moisture readings that professionals can confidently rely on.
Material Settings
Offers precise measurements that satisfy diverse requirements across different materials.
Durability and Build Quality
Built with a solid, durable case that withstands the rigors of job site use without damage.

The Tramex Moisture Encounter ME5 is a handy pinless moisture meter designed to detect moisture in wood, drywall, and various building materials without damaging the surface. It offers dual-depth measurement, allowing you to check moisture near the surface (up to 0.4 inches) or deeper inside (up to 1.25 inches). This feature is useful if you need to compare surface moisture with core moisture or avoid interference from coverings. It measures wood moisture content in the 5-30% range and provides a comparative scale for other materials, which covers most typical needs. The meter is pre-calibrated for different material types like wood, plaster, and masonry, helping improve accuracy across various surfaces.

The analog display is large and easy to read, and an optional high-moisture audio alert can warn you when moisture is detected above normal levels. One of its strengths is Bluetooth connectivity, letting you create moisture maps, generate reports, and share data with the app, which is great for professionals needing documentation. The device is lightweight (about 1 pound) and portable, built with durable plastic suitable for job site use, and runs on standard AA batteries.

While the analog display might feel a bit old-fashioned compared to digital meters, and the measurement ranges, though sufficient for many, might not cover extremely low or very high moisture levels some users want, the ME5 suits homeowners or professionals who want a reliable, non-destructive moisture meter with flexible depth options and smart reporting features. It may be less ideal for those requiring very detailed digital readouts or extreme precision.

Buying Guide for the Best Pinless Moisture Meters

Choosing the right pinless moisture meter can be crucial for various applications, such as woodworking, construction, and home inspections. These devices help you measure the moisture content in materials without causing any damage, which is particularly useful for delicate or finished surfaces. To make an informed decision, you need to understand the key specifications and how they align with your specific needs.
Measurement RangeThe measurement range indicates the minimum and maximum moisture levels that the meter can detect. This is important because different materials have different moisture content levels. For example, wood typically has a lower moisture content compared to concrete. If you are working with a variety of materials, choose a meter with a broad measurement range to ensure versatility. For specific applications, select a range that matches the typical moisture levels of the materials you will be testing.
AccuracyAccuracy refers to how close the meter's readings are to the actual moisture content. High accuracy is crucial for tasks that require precise measurements, such as quality control in manufacturing or detailed inspections. Accuracy is usually expressed as a percentage, with lower percentages indicating higher accuracy. If your work demands precise data, opt for a meter with high accuracy. For general use, a standard level of accuracy may suffice.
Depth of MeasurementDepth of measurement indicates how deep the meter can measure moisture content below the surface. This is important for assessing the moisture levels in thicker materials or ensuring that moisture has not penetrated deeply. Meters with shallow depth are suitable for thin materials or surface-level inspections, while those with greater depth are better for thicker materials or comprehensive assessments. Choose based on the typical thickness of the materials you will be testing.
Material SettingsMaterial settings allow the meter to be calibrated for different types of materials, such as wood, drywall, or concrete. This ensures that the readings are accurate for the specific material being tested. If you work with a variety of materials, look for a meter with multiple material settings. For specialized applications, a meter with settings tailored to your specific materials will provide the most accurate results.
Display and ReadabilityThe display and readability of the meter are important for quickly and easily interpreting the results. A clear, backlit display can be very useful in low-light conditions or for users with vision impairments. Look for meters with large, easy-to-read screens and intuitive interfaces. If you often work in dim environments or need to take quick readings, prioritize meters with high-quality displays.
Data Storage and ConnectivitySome moisture meters come with data storage capabilities and connectivity options, such as Bluetooth or USB. This allows you to save and transfer readings for further analysis or record-keeping. If you need to track moisture levels over time or share data with others, these features can be very useful. For occasional or one-time use, these features may not be as critical.
Durability and Build QualityDurability and build quality are important for ensuring that the meter can withstand regular use and potentially harsh conditions. Look for meters made from robust materials and with protective features like water resistance or shockproof design. If you work in demanding environments, prioritize meters with high durability. For occasional use in controlled environments, standard build quality may be sufficient.
