This paper introduces a field testing and calibrating system that serves the national industrial standards of production safety. The system supervises the monitoring systems of hazardous sources by measuring and evaluating them in the field. The system is designed as a cabinet that can be carried by an automobile. The front end parts of the system are designed as intrinsically safe handset instruments, so that they can be moved into Zone 0 independently and measure the supervised devices as close as possible. Measurement accuracy of the instruments is guaranteed by design. The system also provides a calibration interface with upper standard devices to facilitate periodically automatic calibration itself.
