Carbon Monoxide Analyzer


Put the power of a gas analyzer in the palm of your hand with a CO Series or 2500 Exhaust Gas Analyzer from Blanke Industries. These portable analyzers use a revolutionary new electrochemical sensor that is smaller and more affordable than traditional chemical and infrared sensors. The analyzers are fast, accurate and easy to use.

The instruments are designed to check CO emissions from any internal combustion engine. They can be used on engines powered by gasoline, propane, natural gas and even diesel fuel. Monitoring exhaust emissions is not only important to help control pollutants, it also helps maintain optimum fuel efficiency and extend engine life. These tools will quickly determine the general health of an engine. With a CO Series 2500 Analyzer, any engine can be properly tested and repaired to assure ideal engine performance.
