California Analytical Instruments Model 600

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.
