Point Type Four Gas Detector-TCB2

설명

TCB2 Multi-4 Gas Detector, Detects Carbon Monoxide, Combustible, Hydrogen Sulfide, Oxygen and it is suitable for explosion-proof, toxic gas leakage, underground pipelines or mines and other places, can effectively ensure that the safety of workers’ lives are not harmed, production equipment is not damaged. The detector uses a pumping method to detect gas, and the sensitive element uses a high-quality gas sensor, which has excellent sensitivity and excellent repeatability; the instrument uses embedded microcomputer control, simple operation, complete functions, high reliability, and a variety of adaptation Ability to use graphic LCD display, intuitive and clear.

TCB2 point gas detectors can be combined in four or one in five according to different gases. They are manufactured using convenient wireless remote control operation technology, high-performance sensors combined with sophisticated SMD process, and the instrument has good repeatability and temperature resistance Humidity interference, long service life, easy operation and other advantages.

TCB2 point type gas detector adopts two-wire or four-wire system structure, and the monitoring results can be checked away from the scene by monitoring instruments or controllers. It is suitable for online real-time monitoring of toxic gases and flammable and explosive gases in various environments. The all-in-one combination can intuitively detect the concentration of multiple gases through the LCD screen and display them separately.
