Orion 930 Moisture Meter
Our Score:
at a glance scores orion 930

The Wagner Meters Orion 930 is a pinless meter that can be used for measuring moisture in wood and other building materials. Its rugged build should stand up well to extended use, plus the simple, intuitive design makes it easy to use. We like that the Orion 930 is capable of taking accurate readings down to 4% MC. We also like its dual-depth feature for getting readings at two different depths in the wood. As with every meter in the Orion line by Wagner Meters, the 930 comes with an On-Demand Calibrator, which means the user can do his/her own calibrations. This is a feature no other manufacturer offers.

The Orion 930’s sturdy construction, the ability to accurately read MC at very low levels, the industry-leading warranty, the dual-depth feature, and the included calibrator all make this meter an excellent choice for most anyone seeking a capable pinless meter.


  • Excellent accuracy at lower MC levels.
  • Industry-leading seven-year warranty.
  • On-Demand Calibrator offers field calibration.
  • Dual-depth feature
  • Solid construction; rubber boot and hard case make it suitable for rugged use.


  • Lacks data storage features that some advanced users may want.


Objective Evaluation – Overall Score 4.4 out of 5.0

Accuracy – 4.2 out of 5.0

This meter provided very good accuracy, especially for wood samples below 15% MC. At MC above about 14%, readings for the Douglas fir samples tended to be low when compared to ASTM D4442 oven-dry standards. For the Ponderosa pine samples, testing showed that readings tended to be somewhat high above in the high moisture MC range (at or above 20% MC) when compared to ASTM D4442 oven-dry standards.

Meter Temperature Test – 4.5 out of 5.0

Meter temperature had a relatively minor effect on this meter’s readings at a low meter temperature of 34.8° F. However, a larger effect was observed with a high meter temperature of 110° F. In the presence of low MC, the reading decreased by about 1.1% MC compared to the room temperature reading. In the presence of high MC, the reading decreased by about 2.0% MC.

Wood Temperature – 4.5 out of 5.0

Wood temperature had an effect on this meter’s readings at high moisture content. At a low wood temperature of 33.6° F in the presence of high MC, the readings decreased about 2.0% MC when compared to the room temperature reading. At a high wood temperature of 110° F in the presence of high MC, the reading increased by nearly 4.0% MC when compared to the room temperature reading.

Reading Repeatability – 5.0 out of 5.0

The readings of this meter were highly repeatable, showing very little tendency to vary.

Drift Test – N/A

The drift test was not performed for the Orion 930. As is expected with any pinless meter, there is no observable drift in readings.

Cable Interference – N/A

The cable interference test was not performed because no cable accessories are available for this meter.

Ease of Use – 4.1 out of 5.0

This meter requires minimal use of the manual to become familiar with how to operate it. The manual itself and the species settings booklet provide excellent documentation for resolving issues while using the Orion 930.

Quality – 5.0 out of 5.0

Sturdy, durable construction. The meter itself is unlikely to break or malfunction with normal use and comes with a protective rubber boot. The meter’s seven-year warranty, longer than what other moisture meter manufacturers provide, speaks to its build quality.

Comfort – 4.5 out of 5.0

This meter is ergonomically-designed and fits nicely in one’s hand. It is compact enough for most shirt pockets but may be a bit heavier than one would want for that. It comes with a sturdy, foam-lined plastic case to protect the meter when transporting it from one job site to the next.

Versatility – 3.0 out of 5.0

This is a single-mode meter (pinless mode only). The Orion 930 is capable of giving relative readings in a variety of non-wood building materials.

Range – 5.0 out of 5.0

The Orion 930 reads from 4% to 32% MC. Many handheld wood moisture meters are either incapable of reading at low MC or suffer from significant inaccuracy. Not so with the Orion 930, which excels at very low MC levels.

Features – 3.5 out of 5.0

The Orion 930 shares many of the same features as the Orion 910 but adds one key feature that some users will find important. It allows both shallow (1/4”) and standard (3/4”) depth readings. The Orion 930 offers other handy features, including a hold function, an audible alarm, and a low battery alert. Most notable is the On-Demand Calibrator, which enables the user to perform his/her own calibrations in the field. This is a great feature that no other manufacturer offers.

Customer Service – 5.0 out of 5.0

Customer service appears very knowledgeable and is able to answer all the basic questions, including the cost of repair, turnaround time on repairs, etc. The representative we spoke with was pleasant and his tone of voice gave the impression he genuinely wanted to help. Fast response to both email and telephone inquiries. Manual available online.


Warranty and repair information:

  • 7-year warranty covers product defects
  • Repair comes with a 90-day warranty
  • Turnaround time is 3-5 business days
