Thermo Scientific™ Mini 900 Contamination and Radiation Monitors

Descrizione

Thermo Scientific™ Mini 900 Contamination and Radiation Monitors serve as a portable or benchtop style radiation counter available with a variety of different probes. These designs are particularly attractive for industrial hygiene applications; well established, reliable, convenient and inexpensive radiation meter.

• Large, logarithmically-scaled meter; open scale at the lower end shows background levels while displaying high levels without switching
• Speaker gives audible estimate of radiation intensity Alarm can be set to trip at any level on the scale
• Battery or mains operation using a separate power unit; internal constant current charger for rechargeable batteries included
• Lightweight aluminum case
• Comprehensive manual containing tables, curves of response to radiations, and other useful information
• Several configurations available
• Battery or line powered
• Very affordable
• Packaged in a durable, lightweight aluminum case
• Equipped with a choice of GM or scintillation probe, matching logarithmically-scaled meter, and extensible cable
• The Mini 900E and Mini 900EP15 are available scaled in counts per second or counts per minute

Type R:

• Monitoring High Level Dose Rates A monitor scaled over the range 0.5 to 5000μSv h-1 (0.05 to 500mR/h)
• G-M tube is compensated to give a useful response from 45keV to 1.5MeV and above
• Not recommended for monitoring X-radiation from apparatus operating below 75 kVp

Type G:

• Monitoring for Low Environmental Dose Rates Highly sensitive performance
• Scaled over the range 0.05 to 75μSv h-1 (0.005 to 7.5mR/h)
• Useful energy range: 55keV to 1.5MeV and above
• Not suitable for monitoring X-radiation

Type D:

• Uses partially compensated G-M tube to obtain an extended low energy response
• Scaled over the range of 0.5 to 1000μSvh-1 (0.05 to 100mR/h)
• Useful energy range: 30keV to 1.5MeV but response is maintained down to at least 17keV
• Suitable for measuring radiation from X-ray apparatus operating at or above 45kVp

Type X:

• Scaled 0.5 to 2000 counts per second
• Uses an end window G-M tube without energy compensation
• Sensitive to radiation down to 10keV
• Useful for locating X-ray leakage from a variety of systems including high voltage equipment
• Not intended for measurement but as a relative check device

Includes:

Alkaline batteries, probe, cable, and instruction manual
