PCE Instruments PMI 4 Moisture Meter with Eight Spring Electrodes

Model # PMI 4

The moisture meter is a measuring device for non-destructive moisture measurement on concrete and screed. Here, the spring electrodes of the moisture meter are pressed onto the surface to be tested.
Within seconds, the moisture meter will show the moisture content to the operator. Different scales are already stored in the moisture meter for a wide variety of surfaces. These are available to the operator directly from the moisture meter.
As another special feature, the moisture meter has an automatic shutdown. This feature automatically shuts off the meter if the moisture meter is not used for 5 minutes.

As another special feature, the moisture meter has an automatic shutdown. This feature automatically shuts off the meter if the moisture meter is not used for 5 minutes. This prevents a sudden discharge of the battery at the moisture meter. Another function of the moisture meter is the Max HOLD function. This feature only displays the highest reading to the operator.
