The SSK/NW-GCS5700 handheld gas and nuclear radiation integrated unit is a portable device used for the rapid and accurate detection and monitoring of gas and nuclear radiation levels in the environment. This handheld gas and nuclear radiation detector is not only compact and portable, but also has a variety of practical functions. For example, when radiation levels exceeding preset safety thresholds are detected, these devices will issue audible or other forms of alarm notifications to ensure that users can take timely action. In addition, they can record measurement data for post-incident analysis; and we are equipped with a large-capacity lithium battery that can work continuously for several hours, ensuring stable measurement support in any situation.

It is applied to site safety inspections, hazardous environment monitoring, on-site analysis and detection of gas leaks and other emergencies, and monitoring and detection of nuclear-contaminated environments.

Factory/warehouse environment; Detect toxic or flammable gases that may exist in factory workshops, chemical plants, and warehouses, monitor the concentration of harmful gases in welding and painting processes, and check the sealing of storage tanks and pipelines to prevent harmful gas leaks.

Underground spaces and pipelines; Basements, tunnels, underground pipe networks and other spaces with high closure, detect the concentration of flammable and toxic gases, and monitor the gas conditions inside pipelines to promptly discover leakage hidden dangers.

Entry-exit inspection and quarantine: Conduct radiation detection and gas safety detection on imported and exported goods, cargo, animals and plants and their products to ensure compliance with safety standards, prevent harmful substances from entering the country or being exported to other countries, and protect the ecological environment and human health.

Environmental monitoring; Monitor the content of harmful gases in urban and rural environments, detect chemical leaks at accident sites and natural disaster sites, and monitor changes in nuclear radiation levels in the surrounding environment.

Emergency rescue; Used for harmful gas detection at accident sites such as fires and leaks, assist firefighters and emergency rescue personnel in on-site detection and assessment, and provide gas concentration and radiation level data support for on-site rescue.

In general, this detector has a wide range of applications and can be widely used in factories, underground spaces, environmental monitoring, entry-exit inspection and emergency rescue, providing strong support for safe production and environmental protection.
