Personal X-ray dosimeter DKR-04M (Dose, Russia)

* LLC "Axelbant" is the official dealer of OOO NPP "Doza". Products of LLC NPP "Doza" are sold at the price of the manufacturer.

Personal dosimeter for monitoring of exposure to gamma radiation and X-ray of radiation workers operating X-ray machines and sources of low energy gamma radiation.

Purpose:

• measurement and indication of personal dose equivalent Hp(10) and personal dose equivalent rate Hp(10) of X-ray radiation (excluding industrial X-ray machines that generates ultrashort pulses)

Features:

• measurement of dose received since turning the dosimeter on (current session) and total dose dose accumulated since putting the dosimeter into operation;
• simple setting of alarm thresholds for total dose and dose rate;
• indication of battery condition;
• information is stored in the nonvolatile memory in case of battery discharge or failure.

Basic complete set:

• dosimeter DKR-04 with clip and battery;
• operation manual.
