RAM DA-3-2000 is a further development of the RAM series, a family of versatile, user friendly meters
and detectors designed to give highly reliable alpha, beta, gamma and X-ray measurements.
The RAM DA-3-2000, a microprocessor based meter, includes an internal detector with two energy
compensated GM tubes; ZP1201 and ZP1313 (Air kerma dose equivalent) or ZP1202 and ZP1314 (Ambient
dose equivalent (H*10)) for wide range gamma fields measurement, from 0.5 µSv/h to 1 Sv/h
(50 µR/h to 100 R/h). Meters are available in either Sievert or Roentgen measuring units.
The RAM DA-3-2000 provides a straightforward, fast and reliable method to collect and store monitoring
data on site for later use. The measurements' data, date and time, are stored in a built-in memory. The
stored data records can be downloaded by the SMARTS (Survey Mapping Automatic
Radiation Tracking System) or the RMV (ROTEM Meter View) software packages.
The RAM DA-3-2000 is ideal for use in nuclear power plants, nuclear medicine,
radiography and radiotherapy facilities, life science laboratories, nuclear
research centers and in other industrial applications.
