Description

The CQ-JG-01 is a TDLAS methane sensor probe for integration into host equipment. Its power supply and TTL-level communication requirements belong to a component-selection task. It is not presented here as a complete handheld detector with a user display and alarm package.

Choose the Configuration for Your Measurement

  • Product role: Methane sensing component for integration.
  • Interface: Check the stated TTL-level communication and host-interface requirements in the product specifications.
  • Integration checks: Match supply voltage, connection, measurement unit and enclosure arrangement to the host equipment before selecting the component.

Compare the Relevant Alternative

The CQ-JGYC-01 is the handheld remote laser methane instrument with 30 m, 50 m and 100 m order options. The CQ-JG-01 probe instead needs an integration design. A component and a complete handheld instrument should not be compared as interchangeable purchase versions.

Questions Before Ordering

Can I use this probe on its own as a handheld alarm?

The product is described as a sensor probe. Its host power, interface and user-facing functions must be supplied by an appropriate integration.

Does the handheld model's range apply to this module?

No. Use the probe's own measurement specifications. The remote handheld product's distance options are separate product data.
