EI-R106 Slit Surface Contamination Meter
Product Instruction
EI-R106 Slit Surface Contamination Meter is designed and manufactured by Eastimage. The product is mainly used for surface
contamination detection of items in nuclear power stations, nuclear medical, nuclear research and other nuclear energy facilities and plants, focusing on detecting the presence of radioactive contamination on items, walls, slits and human surfaces, and giving detection results and alarms for exceeding the threshold value. Staff can generally be equipped as required.

– Equipped with a display unit and WiFi module, freely selectable according to the usage scenario
– Built-in WiFi module for data upload and logging analysis
– Metal construction, rugged body, EMC resistant
– Compact size for easy access to slits
Application areas
– Radiation protection of nuclear facilities, nuclear regulatory and source-related enterprises and institutions
– Environmental monitoring department for official duties, disease control and health department for emergency response
– Security precautions for major events, embassies and consulates abroad
– Customs, border control and other nuclear and radiological counter-terrorism, prevention of illegal radioactive material transport and radiological terrorist attacks, etc.
