The GTYQ-QD6100 point-type gas detector is a new type of gas detection instrument produced by our company. This machine adopts high-performance catalytic combustion gas-sensitive components and microcontroller technology, combined with sophisticated SMD process manufacturing. It has the advantages of good repeatability, temperature and humidity characteristics, long service life, and convenient operation. The GTYQ-QD6100 product is suitable for gases in commercial or industrial environments. The point-type gas detector converts the gas concentration signal in the air into a digital signal for display, and adopts a three-wire (4-20)mA current signal output mode, four-wire or two-wire digital signal output for remote transmission. It has the characteristics of long transmission distance and good anti-interference performance. The point-type gas detector is suitable for industrial sites with gases such as oil refineries, chemical plants, liquefied gas stations, gas-fired boiler rooms, refueling and gas filling stations, and spray painting rooms to carry out gas safety detection and alarm.
Functions Features
- High detection accuracy, adjustable range.
- Long service life, high sensitivity, low drift, and stable and reliable operation.
- Self-detection of sensor faults, two-level concentration alarm, with relay output function.
- Digital display of gas concentration and working status on LCD or digital tube.
- Has temperature compensation and automatic zero-point correction functions.
- 4-20mA standard signal output or RS485 digital output, can be uploaded to DCS and PLC systems.
- Infrared remote control mode. The detector can be adjusted without opening the cover, which is safe and convenient.
- Adopts flameproof design and is suitable for dangerous conditions in zones 1 and 2.
