Infrared gas analyser ZKJ

Simultaneous and continuous measurement of 5 gases:

Fields of application

ZKJ is particularly suitable for industrial furnaces, boilers and all types of combustion installations.

Features

  • The reference cell of the double beam principle offers excellent performance
  • Low scales from 0-20 ppm
  • Excellent zero point stability: ± 1% FS per week
  • Integrated interference detectors help reduce cross interference optimally
  • Clear, intuitive interface with advanced diagnostic and calibration functions

Specifications

The ZKJ gas analyser allows simultaneous, continuous measurement of up to 5 gases (NO, SO2, CO2, CO, CH4, N2O) by the non-dispersive infrared method, while O2 is measured by the paramagnetic or zirconia method.
by the paramagnetic or zirconia method. It provides extremely reliable measurement thanks to two mass flow meters that are unaffected by interfering gases. It offers high accuracy, numerous features and ease of use. The ZKJ is particularly well suited to industrial furnaces, boilers and all types of combustion installations.

 

Measurable componentsNO, CO2, CO, CH4, SO2 and N2O + O2
Measuring principleNon-dispersive infrared absorption method.
Single source, double beam.		NO, CO2, CO, CH4, SO2, N2O
Paramagnetic method (measuring element incorporated in theanalyser) or zirconia method (analyser )O2
Repeatability±0.5% PE
±1% FS (for scales below 0-50 ppm)
Linearity±1% PE
Zero drift±1% FS/week
±2% FS/week (for scales between 0-50 ppm and 0-200 ppm)
±2% PE/day (for scales below 0-50 ppm)
Scale drift±2% PE/week
±2% FS/day (for scales below 0-50 ppm)
Response time (for 90% of full scale)- Electrical response time: 15 sec
- Response time when gas flow is 0.5 L/min, is less than 60 sec (including sample gas replacement time).
- Gas replacement time depends on number of sample gases
