Inovision 451 Ion Chamber Survey Meter
This Ion Chamber Survey Meter is a hand-held, battery operated unit designed to measure alpha above 4 MeV, beta above 100 keV, and gamma & x-ray radiation above 7 keV, using the latest CMOS and LCD technology.
Specifications:
- Radiation Detected:
- Alpha: above 4 MeV
- Beta: above 100 keV
- Gamma: above 7 keV
- Operating Ranges: 0 - 5 mR/h, 0 - 50 mR/h, 0 - 500 mR/h, 0 - 5 R/h, 0 - 50 R/h
- Detector: 349 cc volume air ionization chamber; phenolic chamber wall 246 mg/cm2.
- Response Time: Time measured from 10% to 90% of final value for a step increase/decrease in radiation rate such that a range does not occur:
- 0 to 5 mR/h, Range: 8 seconds
- 0 to 50 mR/h, Range: 2.5 seconds
- 0 - 500 mR/h, Range: 2 seconds
- 0 - 5 R/h, Range: 2 seconds
- 0 - 50 R/h, Range: 2 seconds
- Precision: Within 10% of reading
