RAM R-200

The RAM-R-200 is a portable multifunctional, rugged survey meter designed for measuring wide range g amma radiation fields and contamination. The sturdy casing and internal electronics are designed to withstand shocks and vibrations and perform reliably in extreme environments. An internal detector containing two energy compensated GM tubes together with optional external probes will detect, measure, and digitally display both dose and dose rate levels of gamma radiation from 0.1µSv/h to 100 Sv/h (10µR/h – 10,000 R/h), and alpha/beta contamination from 0 to 1 Mcpm.

The RAM R-200 can be used with a three-segment sturdy telescopic rod for the external gamma probe. The RAM R-200 meter and its external detectors include embedded microprocessors, data memory, and communication functions. An audible indication is activated either by frequency fluctuations in accordance with the field strength or chirp for each measured pulse. The RAM R-200’s auto-ranging meter utilizes a combination display consisting of a smoothed digital display for minimum fluctuations, and a two-decade logarithmic analog bar graph for fast response.
