The CLD 88 CY p is capable of  measuring NOx, NH3 and the total NOx-amines! It allows the sequentual measurement of concentrations even in the range of parts per trillion!

When decimals are decisive. The CLD 88 CY p fulfills the requirements of many research groups specializing in detecting and monitoring smallest variations of N-containing compounds such as NOX, NH3 and amines.

NH3 measurement is accomplished by a sequential detection of NOX and NOX-amines. Thanks to its two converters with different characteristics measuring the NOX and the total of NOX-amines allows to determine the NH3. The pre-chamber (p) minimizes zero drift and cross sensitivity. This makes it ideally suited for areas with excellent air quality.

A fascinating technology. The analyser is not only a state-of-the art product in terms of precision and reliability. Its technological base also sets the trend for others. Naturally occurring pressure variations in the sample flow are balanced out by means of an electronic and mechanical bypass system (option r). The heated inlet (option h) minimizes chemical alterations of the sample gas, e.g. salt formation with amines reduce the measured value of NH3. The use of first-rate components guarantees virtually service-free operation. Maintenance simply means annual replacement of filters and membranes besides the consumables requiredby special sampling conditions.

User friendliness. The development of an ECO PHYSICS analyser always requires full user comfort. The user can easily adapt the operation according to his needs and applications by selection of predefined settings.
