NT6108-100 portable surface contamination meter

Product Brief

The NT6108-100 portable surface contamination meter uses a ZnS coated scintillation detector that can be fixed or moved and detects surface contamination directly or indirectly. Mainly used for the detection of radioactive workplace and laboratory work table, floor, wall, hands, clothes, shoes and other surface by alpha or beta radioactive pollution, widely used in environmental protection, public security, military, customs, ports, health, nuclear industry, nuclear power plant system.

This instrument is a liquid crystal display small portable instrument, using the pulse shape discrimination circuit with intelligent analysis algorithm, can automatically distinguish alpha and beta particles, realize the simultaneous measurement of alpha and beta, which influence each other, to the lowest inhibition.

Product features

• new plastic scintillator detector, not inflatable
• built in Geiger Miller tube gamma ray detector
• simultaneous measurement of alpha and beta / gamma without additional probes
• indicates that sound frequency is proportional to activity
• large area LCD digital display
• The probe and the host are connected by a telescopic cable
• small size, light weight, easy decontamination, can adapt to the field and laboratory environmental conditions
• optional Bluetooth, WiFi data transmission
• optional Bluetooth printer
