Protimeter Digital Mini BLD5775 Pin-Type Moisture Meter

Protimeter Digital Mini BLD5775 Overview

The Protimeter Digital Mini BLD5775 is a professional pin-type moisture meter designed for building surveys, restoration work and targeted moisture investigation. It measures at the point where its pins contact the material, which makes it useful when an inspector needs a direct reading from a specific area rather than a broad non-invasive scan.

Protimeter calibrates the meter for wood, while readings taken on materials such as plaster and masonry are displayed as Wood Moisture Equivalent values. This makes the Digital Mini suitable for comparing moisture conditions across a range of building materials while keeping the measurement method simple and repeatable.

Pin Moisture Measurement for Wood and Building Materials

The built-in pins are used for surface measurements and provide a 6% to 99% WME measurement range. When the meter is used on wood, it displays actual percentage moisture content; on other compatible materials, it reports the result on the WME scale.

Because pin measurements are taken at a defined contact point, the Digital Mini is particularly useful when investigating localized dampness, checking suspect areas around leaks or comparing readings from different parts of the same wall, timber element or building component.

Reference Mode for Comparing Moisture Readings

One of the more useful inspection features is Protimeter’s reference mode. A baseline reading can be stored and subsequent measurements can be compared against it directly on the display.

This is practical when surveying a room or building because an inspector can establish a reference in an area believed to be dry, then move through other locations and immediately see how much each new reading differs from that baseline. It turns a series of individual measurements into a more consistent comparative survey.

Optional Probes for Deeper Moisture Investigation

The Digital Mini includes an auxiliary connection for optional probes. Protimeter supports hammer electrodes for deeper measurements in wood, deep wall probes for solid and composite walls, and other specialist accessories.

This gives the meter more flexibility than a basic pin tester. The built-in pins are convenient for routine surface checks, while optional probes can extend the same instrument into jobs where moisture must be investigated deeper inside timber or wall assemblies.

Bluetooth Logging with Protimeter Connect

The current BLD5775 model includes Bluetooth connectivity for the Protimeter Connect app. Measurements can be saved together with time and date information, helping users keep a clearer record of readings taken during an inspection or restoration project.

For professional work, this can be valuable when a site is checked more than once. Stored readings make it easier to document whether a material is drying, remaining stable or showing signs of continued moisture exposure.

Clear Moisture Condition Indicators

A backlit digital LCD is supported by a multicolor LED arc. Green, yellow and red indications correspond to dry, at-risk and wet ranges on the WME scale, giving the user both a numerical reading and a quick visual interpretation.

The meter also includes adjustable hold, backlight, audible warning and moisture-condition settings, along with automatic calibration checks and over-the-air software updates.

Who Should Choose the Digital Mini?

The Protimeter Digital Mini is best suited to users who prefer direct pin measurements and need a rugged professional tool for inspection, building moisture assessment and restoration work. Its reference mode, accessory support and Bluetooth logging make it considerably more capable than a simple entry-level pin meter.

For finished hardwood floors or visible surfaces where even small pin marks are undesirable, a pinless meter may be the better first choice. For targeted building investigation where direct readings and optional deep probes are valuable, however, the BLD5775 is a strong professional option.
