(1) The controller adopts high-speed embedded microprocessor, LED LCD display, humanized touch screen input, controller wall-mounted and desktop (optional) real-time sampling, and the data is quickly processed and refreshed every second
(2) Calendar clock and function abnormal, sound and light alarm mode can be set
(3) Can store over-threshold alarm and abnormal alarm records
(4) Communication mode:
-The standard RS485 interface solves the problems of unreliable communication, insufficient transmission distance and various communication cables
-Network communication mode can realize the wireless communication between controller and detector, controller and various devices, controller and upper computer, and the network is reliable and stable
-GPRS or Internet for global networking (optional)
(5) The alarm threshold of each detector can be set independently, and has upper and lower limit alarm functions
(6) Built-in fault detection, dose rate overload alarm and protection function, to ensure the normal operation of the instrument
(7) When the detector alarms, the host machine prompts the alarm probe number
