Shanghai Enji specializes in the production and sales of sulfide acidification purging apparatus. We currently offer cost-effective models, intelligent sulfide acidification purging devices, and fully automated sulfide acidification purging instruments to meet various needs, with customization options available.

Main Features of the Sulfide Acidification Purging Apparatus for Water Quality

1. Innovative parallel horizontal layout design for convenient and intuitive operation. PLC control ensures strong and stable performance, with a 5-inch touch screen for one-touch access;
2. The instrument's exterior is made of corrosion-resistant materials, offering excellent chemical and thermal stability, and a long service life;
3. Utilizes constant-temperature internal circulating water bath heating, with PID temperature control program maintaining a temperature difference within ±1°C. Features automatic water level control, automatic water replenishment, and low-water alarm;
4. The machine includes a dedicated rack for acid bottle stoppers, making it easy for users to place stoppers during acid addition, reducing the risk of loss, and ensuring safety and simplicity;
5. The main unit is equipped with a dedicated interface for easy external connection to nitrogen sources, and the system includes an overpressure protection system. Each channel is fitted with a pressure stabilizing valve to ensure stable nitrogen flow and conserve nitrogen;
6. Independent control of nitrogen flow for each sample, with a flow rate range of 0.1-1L/min, compliant with national standards;
7. Each channel has a built-in nitrogen flow limiting shut-off valve, allowing for set purging times. Nitrogen is automatically cut off after acidification, conserving nitrogen and protecting samples;
8. The hydrochloric acid inlet, gas inlet, and outlet are integrated yet independent, allowing for non-interfering operation;
9. Vertical acid addition, with the acid addition unit and reaction bottle connected via a ground glass joint. The adjustment knob of the acid addition unit is made of PTFE to prevent corrosion from acids and alkalis;
10. The system presets two working modes to accommodate both water bath and non-water bath operating conditions.
