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 components		NO, CO2, CO, CH4, SO2 and N2O + O2
Measuring principle	Non-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 and scale.
