NOx Analyzers for Measuring Source Emissions

Looking for an emissions level NOx analyzer?

We offer dedicated NOx analyzers, NOx O2 CO2 analyzers, utilizing chemiluminescence, paramagnetic oxygen sensors and infrared CO2 detectors and touch screen interfaces. These analyzers have a built in computer for control, data acquisition, and processing. See below for access to detailed brochures.


The CLD 60 Series

The CLD 60 Series are our basic source emissions NOx analyzers for stack monitoring, and represent our cost effective solution with state of the art data communications. Features include Ethernet connection, dual simultaneous analog outputs from two different ranges, 24 V dry contact closure for powering external devices and automatic cycling between NO and NOx modes.

The 800 Series

The 800 Series is our established, top of the line, compact NOx analyzer with vacuum pump and thermal ozone destroyer inside the case of the analyzer. Also suitable for stack measurements but offering a smaller footprint. The 800 Series also includes dual channel analyzers for simultaneous measurement of NO and NOx, for the most accurate NO2 determination. We also offer the CLD 844 CM hr for simultaneous NOx and ammonia analysis.

We now offer a choice of converters, heated sample inlets, pressure regulation, and multiple reaction chambers. The 800 Series instruments are ideal for compact applications, and offered with advanced options for research applications.

Notes:
Accuracy is dependant on range selected. Highest accuracy shown.
Single reaction chamber models analyze NOx and NOxO2, and are ideal for stack testing or CEMS. Dual reaction chamber models simultaneously measure NO and NOx and calculate NO2.

Features:
A) 0-25% Oxygen
B) Dual ranges and dual sample inlet
C) Heated sample inlet
D) 8″ LCD display & advanced electronics
