A sensor based electrical analogue apparatus (so-called "oxygen analyser") measuring approximately 240 × 220 × 200 mm and weighing approximately 4,3 kg.The apparatus uses coulometric technology in order to detect and measure trace oxygen and paramagnetic technology in order to accurately measure the percentage of oxygen in pure gas streams and multi-gas backgrounds. It includes an LCD monitor to display the results of the measurement. It also includes an audio and visual alarm and analogue and digital outputs and two-way serial communication.The apparatus is used in industrial gas process and quality control. | 90271010 | Classification is determined by general rules 1, 3(b) and 6 for the interpretation of the Combined Nomenclature and by the wording of CN codes 9027, 902710 and 90271010.The apparatus has characteristics and functions of an apparatus for physical or chemical analysis (gas or smoke analysis apparatus) of heading 9027. See also the Harmonized System Explanatory Notes (HSEN) to heading 9027, first paragraph, point (8), which covers electrical gas or smoke analysis apparatus for determining and measuring the content of gases, used to analyse combustible or burnt gases in coke ovens, gas producers, blast furnaces, etc.Classification under heading 9026 as instruments or apparatus for measuring or checking the flow, level, pressure or other variables of liquids or gases is excluded as instruments and apparatus for physical or chemical analysis are more specifically covered by heading 9027 (see also the HSEN to heading 9026, first paragraph, exclusion (d)).The apparatus is a composite product within the meaning of GIR 3(b) and it is to be classified according to the component that gives the product its essential character. Detecting and measuring the oxygen within a gas is considered to be the function that gives the essential character to the apparatus.The apparatus is therefore to be classified under CN code 90271010, as electronic gas or smoke analysis apparatus. |
