[QUOTE="forge, post: 621932, member: 118650"] In labs spectrophotometers use light wave length reflection to analyse gas, and many other things are measured with procedures to isolate things so they can be weighed or otherwise measured. But lab methods have problems for general industrial use so process engineers always look for inferential methods of testing for what they want to know.it is not perfect, but it has to be good enough to do the job. Flow through a pipe without having to measure it in real quantity (buckets full).is measured by pressure drop when it speeds up through a restriction Acidity/pH the acid forms a cell producing electricity, thermocouples dissimilar wires heated where they are joined produce electricity at the other end many gas analyzers actually burn gas to find out what it is by temperature. radiation thermometers read radiated heat for temperature. When we work in the industry and the factory is not working properly it is imperative to know what variables we are actually measuring as distinct from what it says on the control panel. But your dilemma was; where was the sugar coming from, and my answer is it is likely to be a contaminated sample (prob. salty dried sweat) getting into the conductivity sample and the meter cannot tell the difference because it is not a lab quality test. Lab quality tests usually avoid contaminating samples or they have a process to isolate the contamination. [/QUOTE]
