RAM GENE-1 mark II

The RAM GENE-1 mark II,designed for work in extreme conditions, features

a ruggedized casing and backlight and contains a specially designed energy

filter embedded in the cap for dose rate radiation monitoring according to

Ambient Dose Equivalent, with the additional flexibility of a contamination

meter.

The RAM GENE-1 is equipped with a recessed, internal GM pancake

detector using a thin mica window protected by a stainless steel screen.

The transition between measuring dose rate radiation and contamination is

achieved by simply removing or placing the plastic cap.

Features

• Large, four digit, continuous ranging, LCD display

• Simple, three key operation

• Large 1.75" pancake GM detector

• Suitable for alpha, beta or gamma contamination detection

• Unit readouts of count rate (CPS in contamination mode and (µSv/hr) in dose mode.

• Audible and visual (LED) count rate indication

• Smart software provides fast, yet stable response

• Dead time correction

• Alarms for overflow, low battery and detector failure

• Automatic self diagnostic routines

• Durable case with splash resistant keypad
