Product Overview
The Protimeter Surveymaster is a versatile, dual-function moisture meter designed for measuring moisture in buildings and various related structures. Its ergonomic design allows for easy, one-handed operation, enabling assessment of moisture levels both on and below the surface. This instrument is essential for new construction, refurbishing activities, and diagnosing moisture-related issues in existing buildings.
It utilizes both pin and non-invasive technologies to provide accurate readings, helping users understand the moisture condition of materials. All Protimeter instruments, including the Surveymaster, come with a two-year warranty.

The Protimeter Surveymaster features a clear digital display and intuitive controls for easy operation.
Setup
The Protimeter Surveymaster comes ready for use with a 9V alkaline battery included. Follow these steps for initial setup:
- Battery Installation: Ensure the included 9V battery is correctly installed in the battery compartment, typically located on the back of the device.
- Power On: Press the power button (usually marked with a power symbol) to turn on the device. The display will light up, indicating it is ready for operation.
Operating Instructions
The Surveymaster offers two primary modes for moisture measurement: non-invasive (search) and pin-type (measure).
Non-Invasive (Search) Mode
This mode allows for quick and non-damaging assessment of moisture levels up to ¾ inch (20mm) below the surface. It is ideal for initial surveys to identify potential moisture issues without penetrating the material.
- Activation: Upon powering on, the meter typically defaults to non-invasive mode.
- Reading Display: Readings are shown on the digital display as numeric values. Additionally, a color arc (ranging from green for dry, yellow for at-risk, to red for wet) provides a quick visual indication of the moisture condition.
- Usage: Place the back of the meter flat against the surface to be tested. Move the meter across the surface to scan for moisture variations.
Pin-Type (Measure) Mode
For precise moisture content measurements, especially in wood or other porous materials, the pin-type mode is used. This mode requires the pins to penetrate the material.
- Activation: Remove the protective cap to expose the pins. Press the right-hand button on the device to switch to pin-type mode.
- Reading Display: Similar to non-invasive mode, both numeric values and the color arc (green, yellow, red) indicate the moisture level.
- Usage: Gently push the pins into the material until they are firmly embedded. Read the moisture content from the display.
Accessories and Probes
The Surveymaster is compatible with a range of accessory probes that extend its functionality. These probes connect via the universal accessory port located on the side of the instrument.
- Pin-Type Extension Probe: Used for reaching difficult areas or for more comfortable measurements.
- Deep Wall Probes: The included 5-inch long, insulated deep wall probes are designed to measure moisture deep within materials. They are insulated along their length, ensuring that only the tip measures moisture. These are particularly useful for assessing moisture in cavity walls (e.g., measuring insulation) or deep into brick and mortar.
- Other Compatible Probes: The universal accessory port supports various other Protimeter pin-type probes, including hammer electrodes, extension pin probes, and baseball probes, offering versatility for different applications.

Calibration Check
The instrument comes with a calibration check device to verify the accuracy of the pin function. It also includes two spare pins for replacement.
Maintenance
Proper maintenance ensures the longevity and accuracy of your Protimeter Surveymaster.
- Cleaning: Wipe the instrument with a soft, damp cloth. Do not use abrasive cleaners or immerse the device in water.
- Pin Replacement: If the measurement pins become dull or damaged, replace them using the included spare pins or genuine Protimeter replacements. Ensure the device is off before replacing pins.
- Battery Replacement: When the battery indicator shows low power, replace the 9V alkaline battery promptly to maintain optimal performance.
- Storage: Store the meter in its protective case in a cool, dry place when not in use.
Troubleshooting
If you encounter issues with your Protimeter Surveymaster, consider the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Meter does not power on. | Dead or improperly installed battery. | Replace the 9V battery or ensure it is correctly seated. |
| Inconsistent or erratic readings. | Dull/damaged pins (pin mode), surface irregularities (non-invasive mode), or environmental factors. | Replace pins if necessary. Ensure good contact with the surface. Allow meter to acclimate to room temperature. |
| No reading in non-invasive mode. | Poor contact with surface or material is too dry. | Ensure the entire sensor pad is flat against the surface. If still no reading, the material may be completely dry. |
