Technical Data
manual
Most Widely used product by Metal Industry in India

RC705 I & E measures contamination in doserate in Siverts / hr (nano/micro), Roentzen / hr (micro), CPS, CPM. It has built in user presettable alarm facility to declare the product as contaminated. Unit gives audio /visual alarms once it exceeds preset level. It is advised to preset the alarm at least 1.5 times or more than background radiation level, at that place.

Unit can detect less than 0.05µSv/hr in a field of 0.2 µSv/hr during a period of 1 sec (when tested with Cs-137 and Co-60).
