Key Features

• Energy-Compensated GM Tube: Unlike standard detectors, the energy-compensated tube ensures consistent accuracy across a wide energy spectrum (48 keV to 1.5 MeV), reducing measurement errors caused by varying radiation energies.

• Real-Time Monitoring: The integrated LCD screen displays instantaneous dose rates and cumulative totals, allowing for immediate awareness of radiation levels.

• Dual Alarm System: Equipped with both audible and visual threshold alerts. Users can set custom safety limits to receive warnings the moment radiation levels exceed safe parameters.

• High Sensitivity: With a sensitivity rating of 80 CPM (Counts Per Minute), the SF999 is capable of detecting even minute fluctuations in background radiation.

• Extended Battery Life: The 1500 mAh lithium battery supports long-duration field operations and is easily recharged via a standard USB connection.

• Portable and Lightweight: Weighing only 500g, its ergonomic handheld design is optimized for mobile inspections and emergency response scenarios.
