4 Introduction
The Signal NEBULA range of gas analysers uses reference-method Tunable Diode Laser
Spectrometry (TDLS) technology to determine the Ammonia (NH
3
) content of gas samples.
Specifically designed to be versatile and reliable, the Nebula can be used in a multitude of
applications. These include Process control (incineration & combustion), emission monitoring
and environmental safety (leak detection, toxicity etc.). Proprietary digital flow and
temperature control, together with Signal’s world
-class Series 4 electronics package, provides
superior performance across the board.
•

•
Fully automated calibration;
•
Continuous measurement of Ammonia (NH
3
);
•
