產(chǎn)品描述：

Two-in-one instrument: gamma radiation dosimeter and chemical detector in single housing;

Continuous measurement of ambient Dose Equivalent Rate and Dose Equivalent of gamma radiation up to 10 Sv/h (1000 R/h), and 10 Sv (1000 R) respectively;

Simultaneous, independent detection of organophosphorous compounds (Sarin, Soman, V-gases) and arsenic-containing substances (Lewisites);

Audible and visual alarms. Preset thresholds for gamma radiation dose and dose rate and concentration of steams of toxic substances;

High contrast OLED indicator for clear information representation even with bright solar illumination interference;

Non volatile memory for data storage;

IR port for data download of instrument’s operation history to a PC;

The instrument can be connected to the on-board power supply or AC main line;

Waterproof and shockproof case;

Clock-calendar function.
