The SPT-03 area gamma radiation monitoring system includes a host and gamma probes. Each host can simultaneously connect multiple gamma probes (the number of probe connections can be increased according to demand), and is equipped with an external alarm light and an audio alarm device. Four measurement data channels can be displayed simultaneously on a 7-inch LCD screen, and various parameters can be set through touch operation. Each channel can have its own alarm threshold set, and any abnormal situation in each channel can be indicated by an alarm on the screen, along with an audible and visual alarm.

Instrument features:
Adopting a 7-inch capacitive touch screen design, it can be operated in two ways: touch and physical buttons
Bilingual operation interface in both Chinese and English
A single host can mount up to 16 probes
Capable of outputting 5-20mA analog and switch signals
RS485 standard interface, 800 meter long-distance transmission
Internally, it can be equipped with 4G modules, WiFi modules, Bluetooth modules, and 433M data transmission modules, providing diverse data transmission methods.
host part
Host shell: Aluminum alloy integrated machined shell
Screen display: 7-inch LCD display, capable of displaying 4 channels of data simultaneously
Each probe displays: probe number, probe position, dose rate (μ Gy/h, mGy/h, Gy/h), alarm indication, etc
Alarm threshold: dose rate exceeding threshold alarm, probe failure alarm, etc. Each alarm threshold is continuously adjustable within the measurement range
Setting method: It can be directly operated through the touch screen or set through physical buttons. Administrator permissions are required to enter the setting state
External alarm: LED alarm light with high decibel buzzer installed
Power supply: External 220V power supply, internal backup battery, can provide normal operation for more than 2 hours without external power supply when fully charged.
