The Bridge Analyzer 5 Gas Analyzer measures Carbon Monoxide (CO), Carbon Dioxide (CO2), Fuel Dependent Hydro Carbons (HC), Oxygen (O2) and Nitric Oxide (NOx). The 5 Gas Analyzer comes in a hard case with all accessories as a complete, ready-to-use gas analyzer.  Turn on the power switch, connect the hose and probe, push the Zero button.  When the Zero is complete, the analyzer is ready to measure exhaust emissions gas. There are three power input options which will recharge the internal batteries. Accessories include a stainless steel probe assembly, easy storing sample line, and a built-in water trap and particulate filters to protect the internal infrared optics of the analyzer.  This valuable tool in the hands of your technicians will pay big dividends in allowing your business to tune and confirm a properly functioning engine.

This analyzer has been produced for nearly 20 years. Various enhancements and upgrades over that time have allowed this 5 gas analyzer to provide owners with high quality, reliability, and durability. Hundreds of satisfied customers give proof that when you purchase a Bridge Analyzer, you have made a good investment.

Bridge Analyzers offers factory service and calibration for all analyzers over the course of their service life. We are there for you when you need support and service. We know that keeping an exhaust emissions analyzer fully functional and ready to use is important for our customers.
