Do damp meters work?
You might have heard that damp meters should not be used on surveys for issues of dampness, why is this? Here's the thing, electronic moisture meters do not detect moisture, they measure conductivity and interpret that as moisture, this because water conducts electricity. An implication of this is that other conductive materials can trigger these meters and the general conductivity of a base material can also influence a reading, i.e. concrete, plaster, metal (angle beads for example), and salts can all trigger a meter. Surely this makes them useless??? No.
