The Protimeter BLD5777 Reachmaster Pro is a non-invasive moisture meter for the rapid assessment of moisture conditions in buildings, built to reach floors, hard to reach walls and ceilings without ladders or working on hands and knees. Initial moisture surveys can add significantly to inspection time, and the telescopic design makes those measurements quicker and safer while keeping the operator on the ground.
The instrument splits into a sensor head and a tilt-adjustable colour display that communicate wirelessly. The telescopic handle adjusts from 685 mm to 1219 mm, and the sensor takes instantaneous non-invasive readings over a measurement range of 60 to 999 ppm. Depth of measurement runs to roughly 70 mm minimum and up to 120 mm, varying with the material under test, and surface moisture does not adversely affect the reading. The colour display shows red, yellow and green zones, with an audible alarm, adjustable sensitivity to home in on a moisture source, auto shut-off and a multi-language menu. Simple field recalibration and user firmware upgrades keep it current.
The display unit takes 4x AA batteries and the sensor head 2x AA, giving around 80 hours of continuous operation. The replaceable sensor wear plate includes a wear indicator and one spare. The Protimeter BLD5777 Reachmaster Pro weighs 700 g, operates from 0 to 50 degrees C and conforms to CE, RoHS and ETL. It is used in flood damage restoration, flooring and home inspection, EIFS, rubber roof leak detection and fibreglass marine hull inspection. Supplied by BAMR, South Africa's authorised Protimeter distributor.

When to use the Protimeter Reachmaster Pro
You need to assess moisture on surfaces that are out of normal arm's reach, such as high walls or under-floor zones. The Reachmaster Pro pairs a non-invasive sensor head with a telescopic handle and a wireless display, so you can scan awkward areas without invasive probing.
- 1Reach without a ladderA telescopic handle from 685mm to 1219mm lets you survey high or awkward surfaces while keeping the display in hand.
- 2Wireless sensor and displayWireless communication between the sensor head and display means you can read the result comfortably even when the sensor is extended away from you.
- 3Colour zones for fast judgementA tilt-adjustable display with red, yellow and green zones, plus an audible alarm, lets you flag wet areas quickly while scanning.
- 4Long survey runtimeBattery life of 80 hours of continuous operation supports long survey days without swapping cells mid-job.
