The Protimeter Surveymaster comes with several probe accessories and features two modes of operation. One is a search (pinless) mode that quickly scans samples and provides a relative reading using a capacitive-coupled sensor. The other is a measurement (pin) mode that provides moisture content readings using two pins inserted into the sample.
The Surveymaster is designed for use on wood, wood floors, and a variety of other building materials. Moisture levels are displayed digitally and synchronized with a color-coded LED scale that provides a quick visual check of moisture condition.
Despite issues related to quality, this meter’s dual modes of operation may make it worth considering for some applications.
Pros
- Two modes of operation: search and measure
- Comes with calibration check device
- Audible and visual alarm
- Color LED indicator in search mode gives quick visual feedback
Cons
- Supplied pins tend to break easily
- Wiring problems in both the meter and its accessories
- Adjusting for species and temperature requires using tables
- Surface moisture significantly affects readings

Objective Evaluation – Overall Score 3.8 out of 5.0
Accuracy – 4.0 out of 5.0
This meter showed reasonable accuracy from 7% through 20%. It does not have the capability to measure below 7%. As moisture content increased above 20%, accuracy fell off when compared to ASTM D-4442 oven dry standards.

Surface Moisture – 1.0 out of 5.0
Surface moisture had a significant effect on this meter’s reading, increasing the reading 11.1% above 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 – 4.3 out of 5.0
Meter temperature had an effect on this meter’s readings, especially when the moisture content of the wood was low.
A low meter temperature of 34.8° F in the presence of low MC increased the reading by 2% when compared to the room temperature reading. In the presence of high MC, the reading decreased by only 0.4%.
A high meter temperature of 110° F in the presence of low MC increased the reading by 1.6% compared to the room temperature reading. In the presence of high MC, the reading decreased by 0.4%.

Wood Temperature – 4.0 out of 5.0
Wood temperature had an effect on this meter’s readings, especially at lower temperatures.
A low wood temperature of 33.6° F in the presence of low MC increased the reading 2.3% when compared to the room temperature reading. In the presence of high MC, the reading decreased by 2%.
A high wood temperature of 110° F in the presence of low MC increased the reading 0.8% above the room temperature reading. In the presence of high MC, the reading increased by only 0.7%.

Drift – 4.0 out of 5.0
This meter showed a small drift of 0.2% after three seconds.
Cable Interference – N/A
The cable interference test can only be performed when the meter’s cabled accessories are being used. Refer to the review for the GE Surveymaster hammer probe for the results of the cable interference test.

Ease of Use – 2.8 out of 5.0
With only two buttons to push, this meter is fairly simple to operate. Little use of the manual is needed to get started. Documentation in the manual is clear and easy to understand. Adjusting readings for high or low wood temperature must be done by hand as there is no table provided in the manual.
Quality – 3.0 out of 5.0
Although this meter appears to be solidly built, we found some issues with quality during our testing, including problems with pin durability and with internal wiring in both the meter and the hammer probe.
Comfort – 4.0 out of 5.0
Ergonomically designed to fit nicely in one’s hand, this meter is also compact and fits easily in a shirt or jacket pocket.
Versatility – 2.0 out of 5.0
The Surveymaster features two modes (pin and pinless) for detecting and measuring moisture. Species adjustments must be made using a table supplied with the meter. The LCD display has to be viewed upside down when pins are inserted into wood samples, which can be inconvenient when working in tight spaces.
Range – 2.3 out of 5.0
The Surveymaster reads from 7% to 30% on wood. It is not capable of taking measurements when moisture levels are low.
Features – 3.2 out of 5.0
Readings are precise to the nearest 0.1%. Features a low battery indicator, both audible and visual alarms, and a calibration check accessory. Lacks a HOLD function that would be handy when working in tight spaces.
Customer Service – 4.5 out of 5.0
Customer service appears knowledgeable and is able to answer all the basic questions, including the cost of repair, turnaround time on repairs, etc. Warranty is one year. Fast response time to both telephone and email inquiries. Manual available online.
