NOx Analyzers for Measuring Automotive Exhaust Emissions

Unparalleled Performance

The Supreme Line analyzers have an unequaled range of operation and the lowest detection level for an automotive analyzer. They offer an integrated hard disk with nearly unlimited storage capacity for data logging, and they can be operated via integrated touch screen or remote Internet connection.

A tilted and adjustable front panel optimizes display readability, or you can add an external monitor. The clear layout of the menu structure enables you to take advantage of all analyzer functions almost intuitively, and the structured SQL database lets you easily export data.

NO and NOx are simultaneously measured, while NO2 is calculated and displayed. The AK protocol is standard with this remarkable instrument.

The CLD 800 series

The CLD 800 series is our standard research line of analyzers, and offers many advantages over our earlier products, the 700 Series. By including an integrated vacuum pump and thermal ozone destroyer inside the case of the analyzer, the system is much more compact and efficient.

We offer a choice of converters, heated sample inlets, pressure regulation, and multiple reaction chambers. The CLD 800 series instruments are ideal for compact applications with reduced voltage requirements.

Notes:
Accuracy is dependant on range selected. Highest accuracy shown.
Single reaction chamber models analyze NOx or NO, and are ideal for fast response applications. Dual reaction chamber models simultaneously measure NO and NOx and calculate NO2.
