Tramex SMM5 Offers

Determine moisture content by applying a high-audio frequency signal between soft rubber electrodes on the instrument base. Send meter readings instantly to a Tramex Meters App on mobile devices by Bluetooth.

Features

• Three ranges of non-destructive sensitivity: hard wood/shallow depth/glass reinforced plastic (GRP)
• Dual-depth penetration allows for comparative of surface and core moisture to help establish the depth of any moisture within GRP composites
• Deep signal penetration, up to 1¼" (30 mm) in wood and GRP, detects elevated moisture at depth without having to damage the materials being tested
• Shallow depth scale is designed to have a field penetration of up to ⅜" (10 mm)
• Shallow-depth scale is comparable to pin readings, reading in a smaller, more precise footprint
• Wide range of readings from 5 to 30% on wood scale, and 0 to 100 on comparative scale for GRP
• Detects excess moisture hidden in GRP boat hulls, decks and coach roofs including sandwich or cored structures
• Bluetooth connection to accompanying iOS and Android App allowing for geo-tagged supportive image-based documentary evidence of moisture measurements and readings
• Hold function which enables the user to "freeze" the reading, useful when taking readings where the meter face may not be visible
• High moisture audio warning tone which can be enabled or disabled
• Large clear easy to read analog display giving meaningful readings
• Rugged ergonomically designed enclosure

How it works

GRP composites and hardwoods are non-conducting materials, nevertheless their electrical properties change with increasing moisture content. This meter determines moisture content by applying a high-audio frequency signal between a pair of soft rubber electrodes on the instrument base. A third electrode provides genuine shallow range measurements on a smaller footprint. Capacitive coupling between the electrodes and the sample allows impedance to be determined. This is interpreted as a moisture value and displayed on a large, clear moving coil meter. Additionally, meter readings may be sent instantly to a Tramex App on Android and iOS mobile devices by Bluetooth.

Uses

• Identify osmosis problems before blisters appear
• Identify wet cores in sandwich or cored structures
• Monitor hulls for drying before repairs and osmosis treatments
• Check timber for excess moisture before painting, sheathing or varnishing

Effective osmosis treatment requires the complete removal of the hygroscopic solutes that are responsible for absorbing and retaining moisture and forming osmotic cells in GRP composites. Featuring both deep and shallow modes, this meter is the ideal instrument for locating moisture associated with these solutes to help ensure successful treatment. Marine timbers also suffer from excessive moisture which causes blistering and loss of paints and varnishes. Trapped moisture encourages fungal growth and black fungal staining. This moisture meter enables quick surveying over moisture over large areas and will read through paints, varnishes and sheathing such as Cascover without causing damage, and may be used to find and trace leaks above and below decks.
