Professional dosimeter RD MKS-1009  measures the ambient dose equivalent and the ambient dose equivalent rate of Gamma and X-ray radiation (photon-ionizing radiation), as well as the density of Beta-particles flux.
The device is equipped with two Geiger tubes: Beta-2-1 and Beta-2 M-1, that allows  measurement of Gamma (x-ray) and Beta radiation simultaneously (without preliminary evaluation of the background) and instant display of the measurement results.

Features:

• Simultaneous measurement of gamma-(ambient dose equivalent Gamma and X-rays (ionizing photon)) and beta (flux density of beta-particles) without evaluating radiation background;
• 2-year guaranteed non-calibration interval;
• measurement of the ambient dose equivalent for two users with the registration of the measurement time;
• measurement time - 25 seconds;
•  instant assessment of dangerous radiation levels;
• Instant display of the background values;
• Instant display of exceeding dose or particle flux density over baseline values;
• Operation time: 950 hours (without battery replacement);
• Gamma - and beta radiation thresholds change alarm; 
• Exceeding a threshold level sound and vibro signal;
