The Tramex Moisture Encounter MEX5 offers versatile testing methods, allowing users to assess moisture levels both non-destructively and with an optional pin probe. This guide outlines the steps to effectively use the MEX5 for moisture testing in plywood substrates, providing reliable readings to determine if the subfloor is ready for flooring.
Non-Destructive Moisture Testing
To perform a non-destructive moisture test on plywood using the Moisture Encounter MEX5, follow these steps:
- Power On and Menu Navigation: Start by turning on the MEX5 moisture meter. Access the main menu and select the 'Non-Destructive' mode, which is designed to measure moisture levels without causing any damage to the material.
- Selecting Material and Adjusting Settings: Within the non-destructive options, choose the 'Wood %MC (percentage Moisture Content)' setting. Next, navigate to the Advanced Features in the settings menu to enable the specific gravity feature. This feature allows for adjustments based on the specific gravity of the plywood substrate, ensuring more accurate readings. Set the specific gravity to SG 0.50, which is appropriate for plywood.
- Taking the Measurement: Apply consistent pressure to the MEX5 against the plywood surface and take a moisture reading. In the demonstration, readings of approximately 12.7 and 12.6 units are obtained, indicating the moisture level within the plywood.
Pin Probe Moisture Testing
For a pin moisture assessment, the MEX5 can also be used with a pin probe:
- Inserting the Pin Probe: Insert the pin probe of the MEX5 into the plywood substrate where moisture measurement is desired.
- Menu Selection: Return to the main menu and select the 'Pin Probe' option. Under this mode, choose 'Building Materials' and then specify 'Plywood' to tailor the settings for the substrate being tested.
- Taking the Measurement: Connect the pin probe and take a moisture reading. In the example provided, a reading of 12.8 is recorded.
Comparing Results
The video highlights that the moisture readings obtained through the non-destructive mode (approximately 12.6-12.7) closely match those obtained with the pin probe (12.8), with a minimal variance of about 0.2. This demonstrates that the MEX5 provides reliable and consistent moisture measurements regardless of the pin or pinless testing method used.
Advantages of Using the MEX5 for Moisture Testing
Utilizing the MEX5 moisture meter for testing plywood subfloors offers several benefits:
- Efficiency: The ability to perform non-destructive tests saves time, allowing for quicker assessments of multiple areas within a subfloor.
- Accuracy: The specific gravity adjustment ensures that moisture readings are tailored to the specific properties of the wood, enhancing measurement accuracy.
- Versatility: The MEX5 accommodates both non-destructive and pin probe methods, providing flexibility based on the testing requirements and project needs.
- Decision-Making: Reliable moisture readings enable professionals to determine whether the plywood substrate is adequately dry and ready for the installation of floor coverings, preventing potential issues related to moisture-related damage.
Understanding how to effectively use these features ensures that the plywood substrate is properly evaluated, contributing to the success and durability of flooring installations.
