Gas Exhaust Analyzer Manufacturer,Supplier and Exporter in India
Product Code : EL-AELE-9391
Jlab Export is a leading Gas Exhaust Analyzer Manufacturer,and suppliers in India
Exhaust gas shows how well an engine is burning its fuel, and this analyzer measures it at the tailpipe. It reads HC, CO and CO2 by non-dispersive infrared absorption and measures NO and O2 with electrochemical sensors. A microcomputer then works out the excess air coefficient, lambda, from these readings.

Emission Experiments on a Running Engine
A typical practical runs the EFI Petrol Engine Test Bed up to normal temperature and puts the probe in the tailpipe. Students record HC, CO, CO2, O2 and lambda at idle and at a raised speed. They then create a fault, such as a disconnected sensor or an air leak, and watch the readings move. A rich mixture raises CO and drops lambda below 1. A lean mixture raises O2 and lifts lambda above 1, and a misfire sends HC and O2 up together.
Students can also compare readings before and after setting the ignition with the Digital Advance Timing Light, since ignition timing affects the HC and NO figures.
Frequently Asked Questions
Which gases does the analyzer measure?
It reads hydrocarbons (HC), carbon monoxide (CO) and carbon dioxide (CO2) with an infrared bench, and nitric oxide (NO) and oxygen (O2) with electrochemical sensors. From these it calculates lambda.
What does the lambda value tell students?
Lambda compares the air actually supplied with the air needed to burn the fuel completely. A value of 1 is the chemically correct mixture, below 1 is rich and above 1 is lean. It is the quickest way to judge the mixture from the exhaust.
How should the probe be used?
Warm the engine to normal running temperature, push the probe well into the tailpipe and let the readings settle before writing them down. Check the exhaust for leaks first, since outside air raises the O2 reading and spoils the test.
What power and conditions does it need?
It runs on AC 220 V within plus or minus 10% at 50 Hz. It is used in air pressure from 70.0 to 106 kPa and humidity up to 95%.
Does it test diesel smoke?
No. It is a gas analyzer for HC, CO, CO2, NO and O2. Diesel smoke is checked with a separate smoke meter that measures opacity, so a gas reading alone does not cover a diesel smoke test.
