Bacharach is well-known manufacturer of HVAC equipment, including combustion analyzers.

      Since February 2013, all Bacharach Fyrite Insight Plus and InTech Combustion Analyzers have shipped featuring the new Ambient CO Test Mode. This new test is available in the main menu when the unit is in the Siegert Combustion Measurement mode. The Ambient CO Test is a 15 minute test that will take and record a CO measurement every minute (see picture at right). The display screen will show the measurements for each minute as well as the max CO that it has measured.
