APPLICATION & SELECTION
Methane, carbon monoxide and oxygen in one instrument
The GD3 combines three gas measurements in one instrument: low-concentration methane, carbon monoxide and oxygen. A 128 × 64 LCD presents readings, while RS485 communication and alarm output support connection to a compatible monitoring arrangement.
What to confirm before ordering
Specify all three required gas ranges, the power supply and RS485 connection requirements. Confirm the downstream alarm or power-off interface and ask for the current wiring diagram. Review maintenance and calibration requirements for each sensing element.
Request model-specific documentation
Email antaiair@163.com with the model, gases to be monitored, machinery, supply voltage, interfaces and expected quantity. Ask for the current datasheet, applicable certificates and product support information.
