1、 Product Introduction:

This product is developed and produced by our unit in accordance with the national standards of the People's Republic of China: GB/T16489-1996 Determination of Sulfides in Water Quality - Methylene Blue spectrophotometric method and HJ/T60-2000 Determination of Sulfides in Water Quality - Quantitative method. *Sample pretreatment is required for the determination of sulfides in water quality.

Suitable for the determination of sulfides in surface water, groundwater, domestic sewage, and industrial wastewater (coking, papermaking). It is also applicable for marine environmental water quality analysis and hydrological water environment analysis (watershed water).

This product has the characteristics of easy control, simple and fast operation.

4 10ml absorption tubesWater quality sulfide blowing instrumentApplicable to GB/T16489-1996 "Determination of Sulfides in Water Quality - Methylene Blue spectrophotometric method", wastewater with sulfide content below 0.700mg/L.

National Environmental Protection Administration's "Water and Wastewater Monitoring and Analysis Methods (Fourth Edition)"

3、 Instrument parameters:

Sample quantity: 6

The automatic control of the lifting and rotating of the sample rack and gas distribution system makes the front installation of the sample rack easy to operate.

Nitrogen flow meter control: 0-3L/min.

The nitrogen flow rate of each sample is independently controlled and adjusted, or the needle valve gas flow meter is closed to accurately control and display the total gas consumption.

Heating method: constant temperature water bath, heating power: 1000W.

Temperature range: Room temperature -99 ℃,

Display mode: digital display, temperature control accuracy: ± 1 ℃

Material: Made of all stainless steel material, it has the characteristics of acid resistance, corrosion resistance, and high temperature resistance.

The constant temperature water bath comes with a drain valve, making it easy to drain water.

The absorption color tube is equipped with a PTFE drain valve for easy draining.

4、 Instrument features:

1. Different analysis methods can be selected according to the needs, such as methylene blue spectrophotometry.

2. According to the requirements of the national standard for flow rate, precise control of gas flow rate in 4 channels is achieved, greatly reducing experimental errors.

3. A 250mL large capacity bottle can pre process 4 samples simultaneously.

4. Each reaction bottle is an independent gas path system to avoid cross contamination of samples and save gas.

5. A closed gas path system allows exhaust gases to be discharged outdoors or absorbed for treatment, avoiding harmful gases from harming experimental personnel.

6. Using a constant temperature water bath for heating, combined with a temperature control system, it has good temperature uniformity.

7. Made of high-quality mirror stainless steel material, it has excellent performance.

8. The host application manual lifting system, combined with rotating sample trays, can facilitate experimental operations.

9. Multi colored gas pipelines can quickly clarify gas pipeline systems.
