Nederlands ES-G328 explosion-proof gas sensor is used to detect gas concentration in the air. When the concentration exceeds the preset alarm value, it will send out an audible and visual alarm signal to remind users to take safety measures in time to prevent explosion and poisoning accidents, thereby protecting life and property safety. The transmitter uses imported first-line brand electrochemical sensors, which have the characteristics of rapid response and strong anti-interference ability. After our company’s unique compensation algorithm and multi-stage standard gas calibration, it also has the characteristics of long life, high precision, high repeatability and high stability. With a large-screen LCD display, protection level IP65, explosion-proof mark: Ex d IIC T6 Gb, it can be used in harsh outdoor environments.
