ZHK2750+2751 Radiation Monitoring Instrument

    Instrument Applications 
Designed with industrial-grade, all-metal construction and an integrated design, this instrument is dustproof, waterproof, and resistant to both high and low temperatures. It is the ideal tool for simultaneously measuring multiple radiation dose rates in environments such as environmental laboratories, irradiation chambers, nuclear medicine facilities, molecular biology labs, radiochemistry departments, and nuclear material storage areas. 
    Instrument Parameters 
The controller features a high-resolution 800x480 color touchscreen and a high-speed embedded microprocessor. 
Graphical dot-matrix LCD display with user-friendly touchscreen input. 
Freely switchable Chinese and English operation interfaces; controller available in wall-mounted or desktop versions (optional). 
Real-time sampling with rapid data processing and refreshes every second. 
Calendar clock function with customizable audio and visual alarm modes for outlier detection. 
Capable of storing over-threshold alarm and abnormal alarm records. 
Built-in large-capacity SD card storage for recording abnormal values. 
An external audible and visual alarm device is available, featuring a built-in LED for operational indication and an LED for abnormality alerts. 
Adopts a standard RJ12 interface for convenient on-site installation and construction. 
    Communication Methods: 
Standard RS485 interface resolves the issues of unreliable communication, insufficient transmission distance, and excessive cabling commonly encountered in similar instrument manufacturers. 
Network-based communication method enables wireless communication between controllers and detectors, controllers and various devices, as well as controllers and host computers, ensuring reliable and stable network performance (optional). 
GPRS/3G or Internet for global connectivity (optional); 
    Video Surveillance (Optional); 
Each detector's alarm thresholds can be set independently, and it also features upper and lower limit alarm functions. 
Built-in fault detection, dose rate overload alarm, and protective functions ensure the instrument operates properly. 
The controller is equipped with a built-in detector that can measure the radiation intensity around the controller (optional).

    Terminal Parameter - ZHK2751 
Can be fixed for permanent use, or moved to the desired workplace. 
Optional external high-brightness, high-decibel audio-visual alarm device 
The upper and lower alarm thresholds, as well as the instrument address, can be set arbitrarily. 
Sensor failure alarm, over-range alarm, dose rate alarm 
Optionally equipped with a triangular bracket or a desktop base for placement in easily observable locations. 
High-efficiency detector with high sensitivity and rapid response; LED display clearly indicates the dose rate. 
It can be used independently or combined into a monitoring network, and must be equipped with a monitoring host. 
Built-in radiation intensity LED indicator, enabling quick response to the current dose rate level around the instrument. 
Features a built-in 485 industrial bus interface, enabling wired communication or connectivity via ZigBee and TCP/IP with the control host and the host computer monitoring platform.
