The device comes in two versions - 1203 and 1203M. The difference - the model "M" is an infrared port for communication with PC and CE certificate. 

POLIMASTER DKG-RM 1203 Microprocessor Dosimeter-Clock (hereinafter referred to as the Instrument) is meant for the following:
- Continuous measuring of ambient equivalent dose rate *(10) (hereinafter referred to as MED);
- Measuring of gamma-radiation ambient equivalent dose Н*(10) (hereinafter referred to as ED);
- Measuring of ED accumulation time;
- Indication of current time in hours, minutes and seconds; indication of the date, month and year on digital liquid crystal indicator (display).

Dosimeter to measure the seafood comes with a plastic bag with a lock.

The Instrument was included into the State Register of Measuring Means of the Russian Federation under No. 14960-02.

DKG-RM 1203 Dosimeter can be used by wide range of specialists (personnel of nuclear plants, radiological and isotope laboratories; officers of emergency service, civil defense, fire departments, police; officers of the customs and border services) as well as by wide range of customers for MED and ED gamma-radiation measuring.
