fj3500 type personal dosimeter is a pocket-sized smart instruments. It is more powerful using the latest microcontroller technology produced. Mainly used to monitor the X-ray and γ-ray. The measurement range, can be arbitrarily set values of various alarm thresholds, and sound and light alarm occurs in a timely manner to alert staff safety. The instrument is a good memory, the data can be stored for about a week. The main technical equipment in line with national standards and international standards, is the strong function of similar instruments, small size, low power consumption, compact wearable devices. It is widely used in the nuclear industry, nuclear submarines, nuclear power plants, industrial nondestructive testing, cobalt isotope applications and hospital treatment, occupational protection, nuclear power plants around the residents of the background radiation level monitoring and other fields.
Main features:
● Data storage capacity, with 1,500 hours of data storage capacity.
● adjustable alarm threshold, with a cumulative dose, dose rate, blocking, time-out threshold alarm function, etc.
● automatically record data, or replace the battery power data is not lost
● can be displayed, the cumulative dose, dose rate, working hours, time of occurrence of the maximum dose rate and size, the cumulative dose threshold,
Parameters such as dose rate threshold
● high sensitivity, but also respond to environmental background
● Small size, simple operation
● Anti-electromagnetic interference
