DP22326 pumping benzene detector

First, the product description
DP22326 benzene detector is an intrinsically safe device for continuously detecting the concentration of volatile benzene gas. The instrument adopts the sensor and microcontroller technology imported from world famous sensor manufacturers. It has fast response, high measurement accuracy, good stability and repeatability. The performance of the whole machine is at the domestic leading level, and the parameters can be customized by users, and the operation is simple. The internal use of large-capacity nickel-metal hydride rechargeable battery, long standby; patch package, reliable and beautiful; digital LCD backlight LCD screen display, clear and intuitive; with two-level sound and light alarm function, the preset alarm concentration can be timely and accurate, Intuitive alarm prompt; the instrument appearance adopts special high-strength ABS engineering plastic, stylish shape design, beautiful, feel good and durable.

In summary, the DP22326 benzene detector uses a PID photo-ion sensor. The PID consists of a main part such as an ultraviolet lamp source and an ion chamber. The positive and negative electrodes in the ion chamber form an electric field. The gas to be tested is irradiated by an ultraviolet lamp. The positive and negative ions are generated, a current is formed between the electrodes, and the signal is amplified. PID has the advantages of high sensitivity, no poisoning problem, safety and reliability, and can detect more than 400 kinds of volatile organic gases.
