Brennenstuhl Moisture Detector Review
This Brennenstuhl Moisture Detector can be used on wood and other materials such as concrete, brick, screed and plasterboard. In fact, it can even be used on fabric, carpets and wallpaper.
It has a measuring range of 5-50% for wood and 1.5 – 33% for building materials.
This wood moisture meter is solidly made with a grippy and ergonomic design that makes it very comfortable to use. This unit has two sensor pins at the top which measure the moisture content. It is easy to set up and use, simply insert the battery (which is not included) and you are ready to start. The detector has two settings, one for wood and one for substrates such as brick and concrete. There is a handy guide on the back of the detector, which explains what the readings mean. The unit also comes with a user guide.
This wood moisture meter has a large LCD display which is easy to read. It also has a hold feature meaning it will save the reading on the screen if you are taking readings in awkward places so that you can then read it once you can see the screen. It also has an audible indicator. The unit will shut down after 3 minutes of being inactive to save the battery and also features a low battery indicator. The unit comes with a protective cover for the sensor pins.
Testing this wood moisture meter on the logs I have gave very accurate readings, comparable with those of the woodsman who delivered it. The LCD display was clear and easy to read at most angles. The acoustic indicator was a handy extra but can be turned off if not required.
The build quality and design of this wood moisture meter is excellent, and it will give many years of good service. It does not come with spare pins; however, I can’t see them being required as the pins are so sturdy. Because this meter can be used on a variety of materials and can measure a good range, I feel it is excellent value for money. It’s the best moisture meter for firewood on the market.

Valiant Firewood Moisture Meter Review
The Valiant Firewood Moisture Meter can also be used on firewood and all timber, flooring, beams and joists to detect and measure moisture content.
The unit is well constructed and sturdy with an easy to read screen.
This wood moisture meter has different modes for different species of tree. This would be a really handy function for a knowledgeable woodsman as it offers more accurate results for firewood. Luckily, I had such a knowledgeable person on hand and knowing the species did help us get the most accurate results.
If you do not know the species of wood you are testing, the instructions recommend using mode 3 as most wood falls into this category.
The unit features auto power shut off and a low battery indicator. It comes with a battery and pouch.
This might be the best moisture meter if you are knowledgeable about the species of wood you are burning as it offers very accurate results.
Wood Moisture Meter Buying Guide
When choosing the best moisture meter your decision will depend on what you need the meter for. For example, if you simply want a tool to check the moisture content of firewood then you do not need it to be suitable for brick or plasterboard.
The moisture content range is another important consideration. To check firewood, you need a meter that will go up to around 20% so that you know when a log is too wet to burn. However, if you dry your own wood it can be nice to have a detector that will take the reading of freshly cut wood, so you can best plan the drying position and estimate when it might be ready to burn. An extended range is also ideal for people who work with green wood.
The best moisture meter has different modes for different materials that can give more accurate results. If your meter does not have this facility you may have to calibrate your readings for the type of material you are testing.
If you will need to use your moisture meter in awkward or badly lit places, then a hold feature is useful as the reading will be saved on the screen until you can see it clearly.
A meter that automatically turns off when not in use can save you a lot of expense in batteries. A low battery indicator is also a useful feature.
Why do I need to test the water content in my logs before burning and what reading should I be looking for?
Fuel quality is the most important element in making a successful fire. To burn effectively, either in an open fire or a wood burning stove, the moisture content of firewood needs to be less than 20%. Freshly cut timber has a moisture content of between 30% and 60%, depending on the species and growing conditions. As well as burning poorly, high water content wood will produce more waste meaning you have to clean your stove and flue more often.
I am buying some timber for constructing shelves. What can I do if I don’t want to make holes in the wood?
If you don’t want to create holes in expensive wood, then a pinless moisture detector will be your best option. The circuit inside a pinless moisture meter sends out a signal in the form of electromagnetic waves. The waves create an electromagnetic field over the area of material underneath the sensor. The moisture content is worked out from the signal received back from this. These types of meter are more expensive; however, they will provide you with a damage free, reliable reading on smooth wood.
