How to calibrate a Tramex moisture meter

Tramex ME5 accessory kit

This article examines the complete range of calibration check tools available for Tramex moisture meters and explains how to calibrate a Tramex moisture meter. These tools check and confirm a meter’s accuracy while you’re on-site, ensuring you produce consistent and dependable moisture measurements.

Moisture meters provide their user with a way of obtaining easy, convenient and precise ways to measure moisture content in materials. Such now is the technology involved in the moisture meter these days, many applications are measured more accurately and the moisture level contents and managed on a better level.

The moisture meter is calibrated to wood and wood products and the more advanced models can also indicate temperature and relative humidity. In fact it is fair to say that moisture content control has never been as accessible as it is today.

When working with wood the correct moisture content level in the wood is an integral part of any successful project. The wood can be tested by running a meter along the wood surface with a pinless meter, or by invading the wood with a pin meter. Both methods will give you instant results concerning the moisture content in the wood you want to work with. The moisture meter will be calibrated to wood and depending upon which wood species you are testing, the density setting on the moisture meter has to be correctly set by the user.

All sounds well and good. However the problems begin to occur when you start getting weird and whacky results with your meter. These results appear when the meter is not functioning correctly or when the unit is not calibrated properly. It is essential for a meter to be within calibration and to be verified periodically that it is so. The majority of moisture meters are sold as factory calibrated units and some are even self calibrating instruments. However it is not an unusual occurrence for a meter to fall out of sync.

To remedy a moisture meter that is out of sync the calibration has to be reset. In a lot of cases this means returning your meter back to the manufacture where they can recalibrate your unit in their factory. This can be time consuming and very inconvenient for you if you do not have a back up meter to use in the meantime.

Calibration Checkplates and Boxes

Tramex moisture meters are delivered factory calibrated. Most models boast an accuracy of ±1%, but if your measurement task mandates a high degree of precision, how can you be certain your meter will perform to its intended accuracy? The most accessible and affordable way to test your device is with a Tramex check plate and calibration box.

Tramex calibration tools are compact, straightforward to use, and take mere seconds to do their work – so you can get on with more critical tasks at hand.

To use the calibration boxes and check plates, all you need to do is:

  1. Switch your Tramex moisture meter on
  2. Choose your measurement scale
  3. Apply the meter to the calibration box or plate
  4. Compare the measured reading to the expected reading printed on the box; and
  5. If the readings are the same – continue taking accurate measurements. If the measurements are not the same – it’s time to have your meter professionally calibrated.

There are five model-specific calibration checkboxes and plates available to check your Tramex Moisture Meter’s calibration.
