GM-1, MERCURY

According to the measurement requirements, different versions of Geiger-Müller detectors are available:

• GM-1: single-Geiger detector (up to 1 mSv/h)
• MERCURY: double-Geiger detector (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 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 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 for outdoor installations
• PS-ZB accessory for MERCURY, 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
