Handheld Photoionization Detector

Handheld Photoionization Detector operates on the principle that when target gases are drawn into the gas probe via a pump, the internal sensor immediately detects them. The sensor generates an electrical signal proportional to the gas concentration. This signal undergoes circuit amplification, followed by AD sampling, temperature compensation, and intelligent processing by the CPU, ultimately outputting precise Bluetooth signals, Wi-Fi communication signals, and other wireless signals. Users can capture these signals to connect with smartphones, printers, and cloud platforms, enabling voice/light/sound alarms, vibration alerts, alarm screenshots, and data storage.

The instrument's waterproof design incorporates a rubber housing, meeting the demands of harsh environments. It employs pump-assisted sampling for gas measurement and is equipped with high-quality gas sensors, offering high sensitivity and excellent repeatability. Utilizing embedded microcomputer control, the device features simple operation, comprehensive functionality, high reliability, and multiple adaptive capabilities. It employs a graphic LCD display for intuitive and clear readouts.

The handheld photoionization detector is applicable in industrial parks, schools, chemical plants, smelters, steel mills, coal plants, thermal power stations, water treatment facilities, pharmaceutical workshops, tobacco companies, atmospheric environmental monitoring, research institutions, building construction, fire alarms, wastewater treatment, industrial process control, boiler rooms, waste treatment plants, underground tunnels, oil pipelines, and gas stations.
