Product description
MAXILYZER NG Plus
13
automatic pressure compensation valve ensures fast compensation
in the case of changing atmospheric pressures.
All controls, electrical connections as well as gas and condensate
connections are located on the front panel of the MAXILYZER NG
Plus. In addition, the device features status indicators whose function
is described in detail in subsequent chapters.
Gas sampling probe and heated gas line
Heating the gas from the sampling point all the way to the Peltier gas
cooler avoids accumulations of condensate in the gas supply system
and incorrect measurements of strongly water-soluble gases such as
NO2 and SO2. In addition, this function allows for gas sampling at
temperatures lower than 0 °C.
The integrated micro filter with a filter rating of 2 µm reliably removes
pollution with solid matter and can be easily replaced.
The electrically heated gas line with Pt100 temperature sensors is
available in two lengths (3 m or 5 m). MAXILYZER NG Plus controls
the temperature and indicates the status "TA±" of the heating hose.
The controlled temperature is 100 °C. If the reference temperature is
higher or lower by 10 K, the status LED lights red. The device is
ready for operation when the status LED switches from red to green.
The following functions are monitored and indicated.

Colour coding of the individual operating states:
•
Status LED flashes or lights solid green: The corresponding sys-
tem component is ready for operation and works with the speci-
fied parameters.
•
Status LED flashes or lights solid red: The corresponding sys-
tem component is either not yet ready for operation or the com-
ponent is defective.
•
System status LED does not light up at all: The corresponding
function is of no relevance for the measurement.
