The phrase “infrared oxygen detector” is too vague for an industrial oxygen-analysis RFQ. Oxygen instruments may use paramagnetic, zirconia, electrochemical or tunable-laser principles, while an infrared channel in a multigas analyzer may be measuring other gases. A workable selection starts with...

An electric ball valve for a gas analysis project should be evaluated as part of the measurement path, not as a generic on-off component. The purchase specification needs to define what passes through the valve, the pressure and temperature at the valve, port arrangement, wetted materials, shutof...

First confirm what the device is intended to protect and whether it monitors ambient air...

Direct answer：Before sending an RFQ, ask the industrial PC manufacturer to define the hardware scope, operating environment, interfaces, software image, data responsibilities, lifecycle policy, and test evidence. For a gas calorific value analysis system, also establish who integrates the anal...
