Brief introduction: HS - 4 sulfide pretreatment apparatus is a specifically for sewage, river water, industrial waste water and groundwater in the detection of sulfide, complex acidification blowing air pretreatment process and the development of cost-effective equipment, the company's patent technology is applied to implement the automatic flow control, automatic closed gas circuit control, is suitable for testing - methylene blue spectrophotometry and sulfide sulfur detection - iodine quantity method, the instrument has simple operation, high sample homogeneity, reduce the damage of the harmful gas, large processing sample amount, etc. Areas of application: environment analysis: sewage and industrial wastewater; The Marine environment analysis detection; Analysis of hydrology and water environment; Drinking water analysis: surface water and groundwater Performance indicators: 1. The test method of optional, can choose the required detection method according to the need of detection (methylene blue method and iodine method) 2. Automatic gas flow control function, based on national standard of the requirement to flow, to achieve a maximum of four pathways gas flow automatic control, have the characteristics of each flow flow good consistency, greatly reducing the experimental error. 3. Totally enclosed gas path Experiments of all gases in confined Spaces, blow out air through the exhaust pipe can be directly exported outside or further gas cleaning treatment. To avoid the damage of harmful gases to operators, and to avoid the cross contamination of the sample. Exhaust gas can be exported directly by a line outside, not inside the fume hood, greatly reduces the room inspection requirement for space. 4. Heating mode: dry heat bath. Heating speed, save time, avoid the drainage water bath. 5. Display: digital display temperature control precision of + / - 1 ℃. 6. The all samples: 4. 7. The dimensions: 500 * 350 * 395
