Operation condition of detection unit
- Important : Reference conditions, external: *0°C *3° C, **0 ****0 hPa,RH*0~*0%
Principle of detection - Tunable Diode Laser Absorption Spectrometric (TDLAS)
Wavelength (μm) : CH4 : 1.2 Range : 0~**0 ppm ,***0, ****0 ppm
NH3 : 1.5 Range : 0~**0 ppm, **0, ***0 ppm
CO2 : NDIR Range : 0~***0 ppm *0,**0%
N2O : NDIR Range : *****0 ppm
** Ranges are changeable according to the ordered specification
Displayed resolution : 0.1 ppm (negative values can also be displayed)upto **0ppm TDLAS
TDLAS Accuracy : ± 2% of reading or, ± 0.2 ppm whichever is larger
NDIR accuracy : +/- 2% of FS or 1ppm
Zero drift : over 2 h period - 2% reading
Span drift : over 8 h period - within Accuracy
Max. error on temp. comp of reading/°C : < 0.1 %
Linearity - included in the accuracy
Cross talk/interference - Gas matrix and application dependent
Ambient temp. compensate : Type A : CH4 : **0~*0 °C , NH3 & CO2 : **0~*0°C
Type H : NH3 : **0 ~*5°C
* A: For Ambient sample H: For Heated sample
Meas. gas max. humidity abs. H*0 % application dependent, needs calibration
