Description

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

Recommended for:

  • Research
  • Hospitals
  • Industrial laboratories
  • Academic laboratories
