nCLD 811 M

ECO PHYSICS nCLD 811 M

SupremeLine Gas Analyzer

The nCLD 811 M is the next generation in two-channel emissions monitoring instrumentation. Unique in speed and reliability, the nCLD 811 M is modular designed and allows the continuous and simultaneous analysis of NO, NO₂ and NO_X in raw exhaust gasses with NO_X concentrations ranging from several thousand ppm down to a ppb. Its graphical user interface also individually displays and connects to other instruments’ data.

Description

When Decimals are Decisive
The nCLD 811 M fulfills the requirements of the automotive industry when it comes to producing reproducible and reliable NO_X data. With the heated inlet and the built in automated pressure control system, the analyzer is capable of handling rough samples, such as raw exhaust gas. With a detection limit as low as 1 ppb, the nCLD 811 M is also suited for analyzing bag samples. The instrument has a broad range of capabilities designed to fit into this state of the art NO_X monitor with included temperature stabilization. Furthermore, calibration and adjustment of the unit runs quickly and automatically with all necessary data stored and available.

User Friendliness
The new touch sensitive graphical user interface enables the user to individually adjust the instrument operation and data management according to his/her needs and applications. The bright 7” monitor gives a clear overview and allows numerical and graphical display of values. Multiple digital in- and outputs guarantee a maximal connectivity for your remote operation, control and maintenance of the nCLD 811 M, ensuring unsurpassed precision and reliability.

Compact, Modular and Intelligent!
The nCLD 811 M is manufactured in a new compact and modular layout, in which each essential component of the chemiluminescence analyzer hosts its own CPU and interacts with other CPUs by BUS-communication. This assembly increases accessibility and serviceability by reducing wiring and piping.
