The BL Compact S from Gann is designed as a professional hand held timber moisture meter to be used manufacturers, builders and constructors to determine the estimated % of moisture in the general timber.

Using the sliding hammer electrode with longer insulated 60mm pins, this type of moisture meter system is what the councils, local bodies and building inspectors use in New Zealand for pre-lining checks of the construction of new buildings.
The sliding hammer electrode allows the user to drive the pins into the timber frame or through the gib lining by the hammer action, typically going into the timber at a depth of 20-30mm deep. The 60mm teflon insulated pins on the hammer electrode, help reduce the effect that timber treatments have on moisture meter readings (i.e. H1.2 Boron).

If you use just the moisture meter by itself (with 8-10mm pin length) without the hammer electrode, you will only measure the surface and this often always results in an incorrect result or answer. Sometimes it will be higher, other times lower than the deeper measurement of the hammer electrode.

The BL Compact S meter features a built-in 2-stage wood type correction with a supplied wood type chart to identify which code to choose. The Compact S will also determine the ambient temperature of the wood in case a correction is required to be applied.

The Gann BL Compact S has a 1 Year Manufacturer's warranty covering any defects in materials or workmanship.
