According to the measurement requirements, different versions of Geiger-Müller detectors are available: single-Geiger detector GM-1 (up to 1 mSv/h) or double-Geiger detector MERCURY GMP WR (up to 1 Sv/h). 

All models employ energy-compensated tubes, lodged in high-protection aluminium 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. An internal electronics automatically switches to the suitable GM tube according to the count rate level.

Both the GM-1 and the MERCURY GMP WR detectors are connected to and managed by a SATURN ratemeter, which 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.

Among the special versions and accessories available, we mention in particular:

  • Stand-alone version of GM detectors for direct connection to PC
  • IP65 housing for MERCURY GMP WR for outdoor installations
  • PS-ZB accessory for MERCURY GMP WR, providing battery-operated power supply and ZigBee Wireless communication, and ZB-TC receiver connected to the ratemeter to acquire the data
  • GPS locator for PS-ZB
