1. Destination
and characteristics of radiometer
Dosimeter-radiometer MKS-2001 is the multifunction fixed instrument
with numeral indication of statement, a microprocessor control and
presence of removable detection units (BDMG-04, BDMG-100, BDMG-101,
BDMN-100, and UDZhG-01). The detection units have connected to the block
of measuring BOI-12 by the screened cable. The block of signal system
BIC-17 has delivered for a customer order. It have intended for backup
light and audible signals about overflow by the measured meaning of
fixed thresholds. The dosimeter - radiometer is applied to realization
of monitoring in establishments where are works with radiomaterials and
other radiation - hazardous sources of ionizing radiations.

MKS-2001 has issue information as a digital kind on the LCD display,
light and an acoustic alarm, a communication of information on two
independent standard interfacings RS-232 and RS-485.
The dosimeter - radiometer writes down in a memory: the background
values, the overflow of a threshold the information, the facts of
turning power the dosimeter - radiometer for monitoring behind the
unauthorized circulation. The information noted in memory could not
be removed of the operator.
