Automatic Acid Addition EJ-LHW-100S Fully Automatic Water Quality Sulfide Acidification and Purge Instrument
Water Quality Sulfide Acidification and Purge InstrumentMain Features
1. The entire unit adopts a parallel layout, making operation convenient and intuitive.
2. The instrument's exterior is made of corrosion-resistant materials, offering excellent chemical and thermal stability with a long service life.
3. Utilizes constant temperature water bath heating with PID temperature control program.
4. Automatic water level control, automatic water replenishment, and automatic alarm for water shortage.
5. The main unit features a dedicated interface for easy external connection to nitrogen sources, with an overpressure protection system; independent nitrogen flow control for each sample; built-in nitrogen flow-limiting shut-off valve that automatically cuts off nitrogen after acidification, saving nitrogen and protecting samples. Uses imported proportional valves to automatically adjust and switch nitrogen during the experiment, allowing for time-based and flow-based operation according to standards, with automatic adjustment during the process.
6. The hydrochloric acid inlet, gas inlet, and outlet are integrated yet independent, ensuring non-interfering operation.
7. Automatic acid addition and sample introduction, automatic pipeline cleaning, and automatic waste liquid collection.
8. Two working modes: water bath and non-water bath.
