Microcoulomb анализатор

Model WK-2E Microcoulomb Analyzer-----serial products of petrochemical industry analysis instrument Model WK-2E microcoulomb analyzer is designed by the microcoulomb analysis technology and Faraday law. The sample is injected into the combustion tube, oxidative pyrolysis converts the sulfur to sulfur dioxide which then ows into a titration cell where it reacts with triiodide ion present in the electrolyte. The triiodide thus consumed, is coulometrically replaced and the total current required to replace it is a measure of the sulfur present in the sample injected. The instrument is widely applied in the petrochemical industry and scientific research departments, etc. Specifications: Generating current: ±2 mA Electrolytic voltage: ±30 V Bias voltage range: 0 to 500 mV Analytical element: S/Cl/N Analytical range: S: 0.2 to 5000 mg/L Cl: 0.5 to 5000 mg/L N: 0.5 to 5000 mg/L Error of repeatability: x<1.0 mg/L: <50% 1.0 mg/L≤x≤10 mg/L: <10% x>10 mg/L: <5% Temperature controlling range: room temperature to 1000 oC Characteristics: WINDOWS operating interface Reliable performance Good stability Simple installation Display state, parameter & result of whole process Print various parameters and results
