The GGC-400 water quality sulfide acidification blowing instrument is designed by our unit according to the standards of the People's Republic of China: The GB/T16489-1996 standard for the determination of sulfides in water quality - methylene blue spectrophotometric method (iodometric method) was developed and produced. Fully meet the sample pretreatment requirements for water quality sulfide determination. Suitable for the determination of sulfides in surface water, groundwater, domestic sewage, and industrial wastewater. This product has the characteristics of easy control, simple and fast operation.

Instrument features:

1. Sample quantity: 4, 6
2. 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.
3. Nitrogen flow meter control: 0-3L/min.
4. 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.
5. Heating method: constant temperature water bath, heating power: l000W。
6. Temperature range: room temperature -99oC, display mode: digital display, temperature control accuracy: ± 1oC
7. The use of all stainless steel material has the characteristics of acid resistance, corrosion resistance, and high temperature resistance.
8. The water bath comes with a drain valve, making it easy to drain water.
9. The absorption color tube is equipped with a PTFE drain valve, which allows for free draining.
