Bút thử điện phòng nổ MasterEx 79504
MasterEx 79504 is a pen-sized magnet probe, designed to detect magnetic fields in hazardous areas. Within seconds it is possible to detect 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 MasterEx 79504 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 flowmeters or any other equipment that is working magnetically, even when located in hazardous areas.The MasterEx 79504 comes with an integral test magnet that is securely fit 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 MasterEx 79504 will automatically switch off if it is no longer being used.This ensures a long 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 time
