Arrow-Tech - Model RDS-31AM -Area Monitor

• Radiation detected: Gamma and X-rays, 60 keV...6 MeV; Alpha and Beta radiation w/ external probes
• Ambient dose equivalent H*(10).
• Dose rate display range: 0.01 μSv/h... 1 Sv/h (1 μrem/h...100 rem/h).
• Dose measurement range: 0.01 μSv...200 Sv (1 μrem...20,000 rem).
• Resolution: three significant digits or 0.01 μSv/h on dose rate and 0.01 μSv on dose (1 μrem/h on dose rate and 1 μrem on dose).
• Calibration accuracy*: ± 5%, 137Cs, calibration direction and in the calibration field, temperature +20°C (68°F).
• Dose rate linearity: ± 15% ± least significant number 1 μSv/h... 1 Sv/h (0.1 mrem/h to 100 rem/h).
• Variation of the response due to photon radiation energy and angle of incidence: (R E,A) 71% < RE,A < 135% (60 keV...6 MeV), ± 60°
*Compared to Finnish National Laboratory STUK.

ELECTRICAL CHARACTERISTICS:

• The area monitor used two 6 Volt, 45 Ah batteries along with the 2 AA batteries in the meter.

MECHANICAL CHARACTERISTICS:

• Dimensions: 3.8” x 7.3” x 10.5” (without mount ing brackets)
• Weight with meter and batteries: 6.4 lbs

ENVIRONMENTAL CHARACTERISTICS

• Operating temperature -25°C to 60°C (-13°F to 131°F)
• Storage temperature -40°C to +70°C (-40°F to 158°F)
• Relative humidity: up to 85% at +35°C (95°F)
• Fulfills the RF-immunity levels of applicable standards

• Custom cut enclosure with injection molded insert, both pieces UL94-HB Flame Rated.
• Special high capacity air alkaline batteries
• Multiple mounting options
• Speaker holes and clear cover provide local alarm capabilities
• Built in db9 connection for optional High Rad tolerant external probe
• External Probe connects with standard AMP cable
• With a combination of the new diode detector and removal of rad sensitive components the SD version provides a much greater instrument life in higher dose rates (~20 kR of exposure)
• Special firmware for low current draw for extended run time (<4mA/hr)
