The MinAlarm series of monitors have both local and remote alarm indications. There are a wide variety of available probes to suit a variety of applications, and the user can trust the security of a battery backed mains operation.
Product Detail
The Minalarm 7-10 is a mains operated installed radiation monitor with an audio/visual alarm that can be set to trip at any point on the scale. It is available with a variety of probes to suit different monitoring requirements.
Features
Audio-Visual alarm that can be set to trip at any point on the scale
Semi-Logarithmically scaled meter with an open scale at the lower end to show background levels of radiation while displaying high levels without range switching
Long life (50,000 hr) solid-state visual alarm condition lamps
Connections for alarm relay contacts and analogue output for remote indication of alarm status
Selectable latching/non-latching alarm facility
Integral circuit and alarm check facility
Back-Up operation from an internal lead-acid battery should the mains fail
Fail-Safe operation including a probe failure alarm
Tough metal case for bench or wall mounting
Type 7-10G/GL A sensitive instrument using the MC70 GM tube (G model). The meter is scaled over the range 0.05 to 75 µSvh-1 (0.005 to 7.5 mR/h). The useful energy range is 55 keV to 1.25 MeV and above. The type GL uses the MC71 low inherent background GM tube and is intended for environmental monitoring. These models are not suitable for monitoring X-Radiation.
Type 7-10C The meter is scaled 1 to 2,000 counts s-1 for probes to customer's requirements, e.g., other G-M tubes and scintillation detectors from the Mini range for general beta and gamma monitoring. Scintillation probes from other manufacturers may also be used.
Type 7-10R The meter is scaled over the range 0.5 to 5000 µSvh-1 (0.05 to 500 mR/h). The MC10 compensated G-M tube has a useful energy range from 45 keV to 1.25 MeV and above. It is not recommended for monitoring X-Radiation from apparatus operating below 75 kVp.
Type 7-10RL Compensated G-M tube MC20 with an energy range of 50 keV to 1.25 MeV. The meter is scaled from 0.5 to 1000 µSvh-1 (0.05 to 100 mR/h) with emphasis in the 1 to 10 µSvh-1 (0.1 to 1 mR/h) range. It is not recommended for monitoring X-Radiation from apparatus operating below 75 kVp.
Type 7-12 The 7-12 is a special version that allows the probe to be sited up to 500 m from the instrument. Four matching probes are available. The MC74 covers the range 0.05 µSv/h - 75 µSv/h, MC75: 0.5 µSv/h - 1 mSv/h, MC76: 1 µSv/h - 5 mSv/h and MC77: 5 µSv/h - 10 mSv/h. The energy response of these probes is 85 keV - 1.3 MeV ±30%. The response details shown above are for air Kerma. Ambient dose equivalent H*10 versions are supplied as standard.
Additional Features To augment the visual alarm a red, high intensity zenon beacon can be mounted on top of the case to give 360° viewing. The audible alarm is also replaced by a high output unit.
