IMR 1440FL – Exhaust gas analyzer

IMR 1440FL – Exhaust gas analyzer

The exhaust gas analyzer, IMR 1440FL/COFL, is designed to measure exhaust gases of Forklift Trucks, Generators, and heavy Machinery that are powered by a variety of fuels. According to US regulations, the IMR 1440FL/COFL can measure soot and CO for Forklift Trucks.

If state regulations require NOx, the IMR 1440FL/COFL can be equipped with a NOx sensor. The IMR 1440COFL is equipped with two CO sensors. One CO sensor operates in the low range and another CO sensor operates in the high range.

This new model can also measure the exhaust gas pressure before the soot filter. The measurement of the flue gas temperature, oxygen, carbon dioxide and excess air are helpful for diagnostic reasons and the adjustment of the engine to minimize CO emissions.

A flexible probe, which fits in most exhaust pipes, is inserted into the exhaust pipe and a clamp holds it in place. Measuring exhaust gases is not only important to help control pollutants like CO, but it also helps optimizing fuel efficiency and saving operating costs.

The exhaust gas analyzer IMR 1440FL is designed to measure exhaust gases on Forklift Trucks, Generators, Cars, and heavy Machinery that are powered by Diesel or Gas Engines.

According to regulations it can measure soot on diesel engines and Carbon Monoxide CO on gas powered forklift trucks.

Some worldwide regulations require Nitric Oxides NOx, therefore this analyzer can be equipped with a NOx sensor as well.
