ROOF MONITOR

REMOTE READABLE ROOF MONITOR

This roof monitor takes the functionality of the basic Miner’s Helper and enables the user to gather data and have a visual indication at a distance AWAY from the actual location. The roof monitor is connected to the readout box with electrical cable. The rib box is where the data is collected and a flashing LED gives indication that a certain “user specified” amount of movement has occurred. Read with a Multimeter (sold separately).
