DA-800A online neutron and X/γ radiation alarm instrument is an online continuous measurement and alarm device for neutron and X/γ radiation. It uses a high-speed embedded microprocessor and a 7-inch IPS touch LCD display. It can monitor in real time and respond quickly; it also ensures the simplicity and humanization of operation. A reliable communication method is adopted between the host and the probe, which ensures that the host can display the specific dose rate of each probe in real time, and can indicate the current status of the probe (normal/offline/overload) in real time. In addition, radiation area monitoring software can be selected according to site requirements.
• The high-speed embedded microprocessor is selected to ensure the real-time performance of monitoring data and status.
• It adopts a 7-inch 1024×600 IPS LCD display and a full Chinese operation interface, which is easy to use and easy to operate.
• Dose rate unit switchable (μGy/h, μSy/h).
• One host can mount multiple probes at the same time, the default is four probes (expandable to more than 30).
• With the function of automatically identifying the probe, it is convenient for the staff to replace the probe.
• The alarm threshold is continuously adjustable (factory default high threshold is 25uGy/h, low threshold is 0.0Gy/h).
• The status of each probe can be displayed in real time: normal/alarm/overload/offline.
• The probe has multiple alarm modes, sound and light alarm (standard configuration); it can also be extended to an external alarm, relay switch alarm.
• Each probe has two alarm modes (upper limit alarm/lower limit alarm), which are flexibly applicable to various radiation safety alarm places.
• The host can automatically record the threshold alarm and store it automatically, and it will not be lost after power failure; the threshold alarm record can be queried manually.
• It has a real-time clock function, which can display the year, month and day in real time, and the operation of the clock will not be affected by power failure.
• Communication method: standard RS485 interface, transmission distance up to 800 meters.
• An optional built-in battery is used for on-board dose monitoring and occasions where the working power supply is unstable.
• Optional nuclear radiation online monitoring system management software, which can summarize the dose information of each location, display it in real time, make data graphs, review history, etc.
• Can be customized and developed according to requirements....
• Radioactive waste repository, industrial non-destructive testing
• Isotope application plant area, gamma irradiation
• X-ray diagnostics in hospitals, cobalt therapy, nuclear power plants....

The main function of the nuclear radiation online monitoring system is to monitor, statistically query, and display current data. The backend system connects to the backend data via wireless or wired networks, enabling the query and statistical analysis of historical measurement data, as well as real-time viewing of current monitoring data. The system uses SQL Server 2000 as the backend database, ensuring stable operation. It is connected in real-time with the online monitoring system, guaranteeing data timeliness.

Parameter Settings Interface
The parameter settings interface is divided into three main areas:
1. System Parameter Settings
- Alarm Value Settings: The system will automatically alarm when the monitored value exceeds the set value.
- Auto Login: Can be set to automatically log in to the system when checked.
- Auto Run on Startup: Can be set to automatically run the system after a computer restart when checked.
2. Server Parameter Settings
- This area sets the parameters for the backend database server. All data monitored by the probes are uploaded to the set backend database. Detailed settings can be referenced in the screenshot parameters.
3. Probe Parameter Settings
- This area sets the detailed parameters for up to four monitoring probes, including probe number, IP address, communication port (default 8080), etc. Detailed settings can be referenced in the screenshot parameters.
