Contamination Monitor Type : CM 712 manufactured by NUCLEONIX SYSTEMS is primarily designed to measure Alpha, Beta & Gamma contamination, on work benches, clothing, hands etc., in Radiochemical plants, Nuclear Power plants and other similar installations. It is designed to be table top model or it can be mounted on a pedastal stand. It operates on AC mains 230V, 50 Hz. This unit has a choice of two types of contamination probes for Beta-gamma and two types for Alpha. Unit has built-in memory and can store upto 1000 readings of contamination data. Data stored can be printed or downloaded into PC if required and can be recalled onto display. |
