RAM R-200 Meter

Rugged multipurpose survey meter for wide-range gamma and contamination

Portable, rugged multipurpose survey meter for wide-range gamma fields and contamination. Two internal energy-compensated GM tubes measure dose rate and dose, and with external probes it measures gamma up to 100 Sv/h and alpha/beta contamination up to 1 Mcpm. The meter with its internal detectors is waterproof to a depth of 1 metre, and the detector response complies with H*(10).
