The Lignomat Mini DX/C is a pin moisture meter with two sets of pins. Unfortunately, our testing indicated that this meter has accuracy issues, plus the supplied pins are too short for anything other than measuring moisture near the surface of the wood. This meter comes equipped with built-in, automatic calibration and offers programmable species adjustments with up to 40 settings.
It lacks some useful features such as a HOLD function or low battery indicator. The meter can measure moisture content (MC) from 5% to well above the saturation point of wood. However, our testing indicates that when moisture levels exceed 17%, the meter provides readings that are significantly lower than the actual moisture content.
Because of its accuracy issues and limitations, this meter is not recommended.
- Easy to operate with only one button to push.
- Features species adjustment settings for up to 40 wood groups.
- Internally checks calibration.
- Easy-to-read red LED display.
- Pins are too short for anything but surface measurements.
- Accuracy decreases appreciably above 17% MC.
- Surface moisture significantly affects readings.
- Lacks HOLD function for taking readings in tight spaces.
Objective Evaluation – Overall Score 3.2 out of 5
Accuracy – 3.6 out of 5
This meter provides relatively good accuracy from 5% to 17% moisture content compared to ASTM D-4442 oven dry standards. The readings decreased in accuracy above 17%.

Surface Moisture Test – 1 out of 5
Surface moisture had an appreciable effect on this meters reading, increasing by 10% over the baseline. These results indicate that operating this meter in high humidity environments where condensation may form on the surface could lead to questionable readings.

Meter Temperature Test – 1 out of 5
Meter temperature had an effect on this meter’s readings.
A low meter temperature of 34.8° F in the presence of low MC increased the reading by 3.5% compared to the room temperature reading. In the presence of high MC, the reading decreased by 1%.
A high meter temperature of 110° F in the presence of low MC decreased the reading by 0.9% compared to the room temperature reading. In the presence of high MC, the reading decreased 1%.

Wood Temperature Test – 4 out of 5
Wood temperature had some effect on this meter’s readings.
A low wood temperature of 33.6° F in the presence of low MC increased the reading by 0.6% compared to the room temperature reading. In the presence of high MC, the reading increased 1.8%.
A high wood temperature of 110° F in the presence of low MC decreased the reading by 0.5% compared to the room temperature reading. In the presence of high MC, the reading decreased by 2.3%.

Drift Test – 3 out of 5
This meter showed some drift after 3 seconds.
Cable Interference – N/A
The cable interference test is not applicable to this meter except when cabled accessories are being used. Please refer to the review of the Lignomat DX/C hammer probe for test results.

Ease of Use – 2.5 out of 5
With only one button to push, this meter is easy to operate and requires very little use of the manual to get started. Battery installation requires use of a screwdriver and taking apart the entire meter casing, which is not very convenient.
Quality – 4.3 out of 5
Sturdy and durable casing. This meter appears unlikely to break or malfunction with normal use.
Comfort – 4.0 out of 5
Compact size, fits comfortably in a jacket or shirt pocket. Large, bright, easy-to-read LED display.
Versatility – 2.0 out of 5
This is a single-mode meter (pin), which is typical. With its short pins, this meter is limited to taking readings near the surface of the wood sample. Use of the optional hammer probe or electrode probe accessory is required to take deeper measurements. This meter has 40 possible settings for making species adjustments using a chart for domestic and tropical wood species, including bamboo. It also has a 0-99 reference scale for comparative readings in non-wood building materials such as drywall and plaster.
Range – 5.0 out of 5
According to the manual, this meter’s range is 5% to 55%, but the actual range depends upon the wood group setting that is selected. Due to the fiber saturation point of wood, the accuracy of readings above 28% should be questioned.
Features – 2.5 out of 5
Readings precise to 0.1%. No low battery indicator or HOLD function. Comes with two pairs of pins: 3/16 inch (5 mm) and 7/16 inch (10 mm). Display indicates when moisture content is outside the range that the meter is capable of reading. Calibration is internally checked and automatically adjusted as needed.
Customer Service – 5.0 out of 5
All Lignomat meters come with a 2-year warranty, and a 1-year warranty for accessories. Repairs also come with a 2-year warranty, which is a plus when compared to what other manufacturers typically offer. The representative stated that the average cost of repairs is only $25. Lignomat has its own service center for repairs, with 4-6 business day turnaround time. We received fast responses to both email and telephone inquiries. Manual available online.
