The California Analytical Instruments
Model 600 CLD NO/NOx digital analyzer is designed around
a state-of-the-art 16-bit microprocessor, with 16
digital inputs, 16 digital outputs, 16 analog inputs and
4 analog outputs. The analyzer can be manually operated
from the keypad or remotely via TCP/IP, RS-232C
communications and discrete inputs.
The analyzer display includes screen presentation of all
analyzer alarms. Four levels of password protection are
provided. For precision measurements, the analyzer's
accuracy is increased by entering calibration curve fit
polynomials.
Automatic calibration may be activated locally or
remotely and includes auto cal via preset times. The
analyzer may also display NO, NOX and NO2 via selectable
time and hold commands.
Method of Operation
The California Analytical Instruments Model 600 CLD
Analyzer utilizes the principle of chemiluminescence for
analyzing the NO or NOX concentration within a gaseous
sample. In the NO mode, the method is based upon the
chemiluminescent reaction between ozone and nitric oxide
(NO) yielding nitrogen dioxide (NO2) and oxygen. This
reaction produces light which has an intensity
proportional to the mass flow rate of NO into the
reaction chamber. The light is measured by means of a
photodiode and associated amplification electronics. In
the NOX mode, NO plus NO2 is determined as above,
however, the sample is first routed through the internal
NO2 to NO converter which converts the NO2 in the sample
to NO. The resultant reaction is then directly
proportional to the total concentration of NOx. Local
operation is simplified using the 20 button alphanumeric
keypad with data presented on a back lit LCD display.
All local operations may be performed remote via RS-232
and/or TCP/IP.
