Mini Instruments MinAlarm 7-10R Alarm Monitor, £580

Just one remaining!

This high-quality, mains-powered radiation monitor is made in Britain by Mini Instruments Ltd. It is housed in a tough metal case, for bench or wall mounting.  It has been designed for use in laboratories, work areas, in education, industry and construction. It features a user-settable audible and visual alarm with a loud (400Hz, 90dBa at 30cm) sounder and bright red and green visual indicators showing Safe or Alarm state conditions.
The large semi-logarithmically-scaled front panel meter covers a range of 0.5 to 5000 µSv/h (0.05 to 500 mR/h), without the need for range switching. It is supplied with a Mini Instruments MC10 sensor probe and 3.5 metre connecting cable. The probe is a compensated GM tube with an energy range from 45 keV to 1.25 MeV and above. (Not recommended for monitoring X-Rays from apparatus operating below 75 kVp).

Also included is a mains power cable, a newly installed 12 volt backup battery and a copy of the instruction manual.
Additional features include fail-safe checks for the probe, internal circuitry and the alarm function. The internal sealed lead-acid battery provides backup in case of mains failure.
