Ordering & Support FAQ

How do I choose the right gas detector model?

Please provide the target gas, measuring range, output signal, installation environment, and whether a controller is required. We will recommend a suitable configuration.

Can this detector connect to a gas alarm controller?

Yes. It can be used with a compatible gas alarm controller for centralized monitoring, alarm output, and signal transmission.

What output signals are available?

The detector can support common industrial signal outputs such as 4-20 mA, RS485, or relay output depending on the product configuration.

Can the alarm value be adjusted?

Yes. High and low alarm values can be adjusted according to the monitoring requirements of the application.

Can I request documents before ordering?

Yes. Datasheets, user manuals, wiring diagrams, and available certification documents can be provided upon request.
