Product Instruction
EI-R105 is a cloud-based portable surface contamination monitoring device with a ZnS coated plastic scintillator probe with a sensitive detection area of 170cm2 , designed to detect alpha and beta contamination on surfaces or wiped test samples. The instrument has a built-in WIFI and 4G module for field data transmission. The color HD touchscreen display makes it easy to operate and carry. A cloud server can be set up so that measurement data can be automatically uploaded to the cloud server via wireless and mobile networks,
allowing access to the server and data readings anywhere, anytime, as long as the instrument is connected to the internet.
Functional features
– Based on a unique detection method, the lower detection limit of the instrument is not affected by external exposure
– Built-in WIFI and 4G modules allow you to upload measurement data to the server for subsequent statistics, analysis and display as required
– Built-in industry standard (EJ/T1204) method with automatic evaluation and display of lower detection limits
– Simultaneous α and β measurements with switchable units of cps, Bq, Bq/cm2
– Large HD touchscreen display with manual or automatic sensor to turn on the backlight
– Alarm thresholds are set in two levels
– Automatic deduction of the background function
– A library of over 30 freely editable nuclides
– Extendable with external probe for X/γ dose rate measurements
