General Tools & Instruments (General Tools)

Moisture Meters fall into two categories, pin-type and pinless. Pin-type Moisture Meters measure the resistance between test pins inserted into a piece of wood or a building material and use that reading as a proxy for the object''s absolute moisture level. The wetter the material, the less ready it is to be sanded, painted, finished or covered. A best seller is the MMD4E Pin-Type Moisture Meter. Pinless Moisture Meters rely on the ability of moisture to inductively distort an electric field created by turning on the meter. Although Pinless Moisture Meters can only make relative readings, they are nonetheless useful for pinpointing the source of a leak above a ceiling, and for leaving no unsightly pinholes on a finished surface. The MMD7NP is a best selling pinless moisture meter.
