CLD50 | NO and NO2 Analyser

New in 2021 is the CLD50, our fast CLD designed for both engine and non-engine single channel applications where a 15ms T10-90 response time is sufficient. The CLD50 is capable of both [NO] and [NO₂] measurement directly (NO₂ via LIF) with only oxygen and power needed for basic operation (zero and span gases required for complete calibration). The use of these detection methods ensures minimal cross sensitivities and allows retention of millisecond response times.

In addition to a heated line engine version, Cambustion have developed a super-sensitive yet ultra-fast version for air quality work in response to many researchers requesting faster real time data with a strong emphasis on identifying “gross emitters” entering urban environments and clean air zones. In ambient mode the CLD50 has a lower detection limit of 5 parts per billion while retaining a response time of 100ms, allowing an in-depth look into the real human exposure from passing traffic and other polluters. The equipment is available for on-board mobile applications including “chase studies” with heated/unheated sample line options of various lengths.

Other typical applications include medical research, pre- or post-catalyst engine exhaust [NO] measurement, road infrastructure and clean air zone evaluation, aftertreatment retrofit investigations and many more.
