RITTER · MultiGas 紫外线传感器 NDUV/UVRAS

概述

SO₂ NO₂ NO

为了检测NO，使用了EDL（无极气体放电灯）。在EDL中，N2和O2被转化为NO，并产生选择性的紫外线辐射。有了这种辐射，就可以进行无交叉灵敏度的NO测量。这种方法被称为紫外共振光谱法（UVRAS）。

A combination of both technologies (UVRAS & NDUV) allows simultaneous gas analysis of NO, NO₂ and SO₂ in the lower ppm range, which is particularly important in flue gas analysis (CEM, Continuous Emission Monitoring).

应用程序

便携式气体分析（PEMS，便携式排放监测系统）

Characteristics and Benefits

Group of detectable gases:
SO₂ NO₂ NO
Temperature controlled up to 55 °C
Fast response time < 3 seconds
Durable EDL (> 16000 h)
Flow-independent measurement 0-2 L/min
No influence of gas humidity
No NO_x converter required
Compact size
In »Thermobox« as standard for stable measurement conditions

Recalibration

Readjustment of the zero-point is recommended once a week.
Contamination of the measuring cuvette can lead to shifting of the end-point. Due to the integrated filter, re-adjustment of the end-point is generally not required – but can be performed once a year.
Additionally, cartridges filled with an inert and the respective test gas for recalibration of the zero and end-point can be provided.
Long-term drift is < 1% of Full Scale (F.S.) / 24 h.
