Dosimeter Individual small-sized DKG-Pm1604A
Principle of operation
In dosimeters, it is possible to set two independent alarm thresholds for dose and dose rate, exceeding which is automatically accompanied by an audible alarm. At the same time, the value whose threshold is exceeded is displayed on the instrument display, which ensures timely information to the user about the radiation hazard. In cases where the radiation intensity exceeds the upper limit of the dose rate measurement, the warning message "OL" is displayed and an intermittent sound signal is emitted.
Dosimeters DKG-RM1604A and DKG-PM1604V are equipped with non-volatile memory, which automatically stores up to 1000 history events (dose rate measurements, accumulated dose, cases and levels of exceeding the set alarm thresholds; 500 DER + 500 ED). Using an infrared (IR) communication channel, information from the non-volatile memory of the device can be transferred to a personal computer for further processing and analysis, as well as presentation in the form of appropriate databases as part of a system for monitoring and recording personnel radiation doses.
A sealed, shockproof housing allows the use of devices in adverse operating conditions and, if necessary, to conduct decontamination of dosimeters, and the luminescent backlight makes it easy to read information from the display in the absence of external lighting.
Network functions
Dosimeters can be integrated into the personal dose dose tracking system Personal Dose Tracker, which allows you to keep track of individual doses of external exposure to personnel.
