RAM DA3-2000 Meter
Smart meter for a range of interchangeable external detectors, with internal GM detector
“Smart” meter that recognises a wide range of external detectors and selects the right readout units automatically, for area survey, contamination monitoring, preset scaling and high-dose freeze reading. RAM DA3-2000 has an internal detector with two energy-compensated GM tubes for wide-range gamma; RAM DA 2000 has no internal detector. Data are stored with date and time and downloaded to a PC.
- Detector
- Internal detector (DA3-2000): two energy-compensated GM tubes, ZP1201 and ZP1313 (air kerma) or ZP1202 and ZP1314 (H*(10)); DA 2000 without internal detector1
- Measurement range
- 0.5 µSv/h – 1 Sv/h (50 µR/h – 100 R/h), internal detector1
- Weight
- 1.5 kg including batteries and internal detectors1
