Concrete Moisture Meter - MS300C Wall, Wood and Material Tester

The MS300C concrete moisture meter measures moisture readings for comparison checks on concrete, wood, and wall materials supported by its material codes. It suits handheld site checks where you want to compare several areas of the same material under similar conditions.

Before ordering, confirm that the documented material codes cover your intended surface. Readings from different modes should not be treated as equivalent. Its documented scope is comparative material checks; embedded concrete humidity monitoring is not specified. If you need an embedded concrete moisture sensor, check the specifications or manual for suitability.

Choose the Configuration for Your Measurement

• Material compatibility: Confirm the documented material code for your intended surface before ordering. The ten modes are not interchangeable.
• Measurement range: Check whether the stated 0-70% range and 0.1% resolution suit your intended comparison checks; readings from different material modes are not directly equivalent.
• Test conditions: Consider surface condition, nearby metal, and coatings, which can affect comparative readings. Plan to compare clean, representative areas using the same code and consistent meter positioning.
• Display and handling: A backlit LCD and data hold support viewing and retaining a reading during handheld checks.
• Power: The meter uses four 1.5 V AAA batteries. Check the specifications or manual to confirm whether batteries are included.

Product Details and Specifications

Concrete, Wood and Wall Material Checks

The MS300C concrete moisture meter is a handheld reader for comparison checks on concrete, wood, wall materials, and other materials covered by its selectable modes. It uses a high-frequency principle with automatic temperature compensation for quick material checks.

Choose the Material Code Before Testing

Confirm the material-code guidance for the intended material before ordering. When testing, use the documented code for that material. The ten modes are not interchangeable, so keep the same code and similar test conditions when comparing one area with another.

• Check several clean, representative areas instead of relying on one reading.
• Keep the meter position and selected material code consistent between readings.
• Compare readings taken on the same material; values from different modes should not be treated as directly equivalent.
• Surface condition, nearby metal, coatings, and changing test conditions can affect comparative readings.

Ten Material Code Modes

• 0-70% measuring range with 0.1% resolution.
• Supports 10 material codes for compatible surfaces.
• Backlit 4-digit LCD keeps readings easy to view.
• Data hold, low-battery alert, manual power-off, and auto power-off are included.
• Compact 120 g body is practical for site checks.

Questions Before Ordering

Can I use the MS300C on both concrete and wood?

Concrete, wood, and wall materials are covered when supported by the documented material-code guidance. Confirm the code for your intended material before ordering, and keep that code consistent when comparing areas.

Is this an embedded concrete humidity sensor?

The description identifies the MS300C as a handheld reader for comparative material checks. Embedded installation and continuous humidity monitoring are not specified; check the specifications or manual if your job requires them.

Can I compare a concrete reading directly with a wood reading?

Values from different material modes should not be treated as directly equivalent. Compare readings on the same material using the same code and similar test conditions.

What can affect the readings?

Surface condition, nearby metal, coatings, and changing test conditions can affect comparative readings. Check several clean, representative areas while keeping meter positioning and the selected material code consistent.
