All Geiger-Müller detectors are energy-compensated and lodged in high-protection aluminum cylinders, together with a built-in HV board. MERCURY GMP WR detectors are equipped with 2 Geiger-Müller tubes to reach a wider measurement range. The switching between the 2 GM tubes is automatically controlled by the internal electronics, which continuously surveys the count rate level. A special IP65 housing for MERCURY GMP WR can be provided, which makes possible to install the probe outdoor. The PS-ZB accessory for MERCURY GMP WR detectors provides local power supply (battery operated) and ZigBee Wireless communication. A receiver (ZB-TC) is then connected to the ratemeter to acquire the radiological data. Upon request, a GPS locator can be optionally installed in the PS-ZB. Both the GM-1 and the MERCURY GMP WR detectors are managed by a SATURN ratemeter, connected through a dedicated cable; the ratemeter provides power supply, signal processing and data visualization. Each detector-ratemeter couple forms a monitoring unit, which can be connected in a network to a central host PC running 5700 sMON management software. Special stand-alone version of GM-1 and MERCURY GMP WR detectors are available for direct connection to a host PC. Ratemeter Geiger detector Monitoring system
