TCB3 point type O3 detector has LCD/LED display and sound and light alarm function to detect ozone alarms from Gas Monitor Point for the detection of levels of Ozone (O3). it is the use of high-performance imported catalytic combustion, electrochemical, infrared dual beam gas sensor, combined with sophisticated SMD process, which has good repeatability and resistance to humidity temperature interference. Long life, easy operation and other advantages. It is suitable for detecting gas leakage concentration in various industrial environments.
TCB3 point-type gas detector can convert the concentration signal of gas leaking in the air into an electrical signal for remote transmission. It adopts three-wire 4-20mA, four-wire RS485 bus (or two-wire), passive switch and other signal structures, which are monitored by The instrument or controller host is far away from the scene to view the detection results.
TCB3 point gas detector products are suitable for industrial sites that use flammable and explosive products, toxic and harmful industrial sites, such as oil refineries, chemical plants, liquefied gas stations, gas boiler rooms, gas refueling stations, paint spraying rooms, pharmaceuticals, iron and steelmaking Carry out gas safety detection, alarm control and other places.
