Bacharach Combustion Analyzers

My October 2019 product review focuses on combustion. When performing combustion testing in the field, it is important that you can depend on your combustion analyzer. I have found that the Bacharach Intech and Insight Plus combustion analyzers are the leaders in these areas.

Let’s look at both devices’ specifications and compare them.

Bacharach CombustionAnalyzers

These specs are for Intech Analyzer:

• O₂ Range: 0% – 20.9%
• CO Range: 0 – 2000 ppm
• Stack T: – 4 to +1202 degrees
• Comb Air T: – 4 to + 212 degrees
• Draft P: N/A
• Ambient Use: 23 to 113 degrees
• Reporting App: Yes
• Warranty: 2 years
• Built-in Diagnostics: N/A.

These specs are for the Insight Plus:

• O₂ Range: 0% – 20.9%
• CO Range: 0 – 4000 ppm
• Stack T: – 4 to +1202 degrees
• Comb Air T: – 4 to + 600 degrees
• Draft P: +/- 40-in.w.c.
• Ambient Use: 23 to 113 degrees
• Reporting App: Yes
• Warranty: 2 years
• Built-in Diagnostics: Yes.

Field serviceability is a major factor in overall operating expense of combustion analyzers. Bacharach is the easiest to verify sensor operation. Changing both sensors when necessary is easy.

The CO sensor can be field calibrated, or you can buy calibrated CO sensors. CO sensors normally last more than five to eight years.

Based on 30-plus years of using Bacharach analyzers, I found that most CO sensors rarely need to be calibrated more than every two years. They can always be checked by comparing their CO reading with another analyzer.
