Intrinsically-Safe Magnet Probe
Magnet-Ex 12 is a pencil sized magnet probe, designed to detect magnetic fields in hazardous areas. Within seconds it is possible to detect as to whether or not a solenoid valve is electrically activated. Connection to electronic circuitry or opening of terminal boxes is rendered unnecessary. The highly sensitive probe point of the Magnet-Ex 12 only needs to be brought near the coil of a solenoid valve, if the probe shows a red light this indicates that the magnet is activated. In the same manner tests can be carried out on flow-meters or any other equipment that is working magnetically, even when located in hazardous areas.
The Magnet-Ex 12 comes with an integral test magnet that is securely fitted in such a way that it cannot be easily lost. Using this magnet, tests can be carried out to establish the working state of both unit and batteries. After any check the Magnet-Ex 12 will automatically switch off if it is no longer in operation. This ensures a long lasting battery life. The clip attached to the instrument's side secures it from accidental loss and allows the maintenance engineer to easily carry it at all times.
