Introduction: The ultra-pure water machine for economical laboratories is suitable for ordinary experiments, preparation of standing solutions, basic experiments, microbiological examinations, routine chemical analysis, front-to-bottom support for imported ultrapure water machines, and matching water for salt spray boxes. Features: 1. One-touch button operation design, simple, fast and convenient; 2. The system has functions such as water shortage shutdown protection, power failure automatic reset, full water automatic shutdown, ultra-low voltage protection, automatic start flush and other functions; 3. The LCD backlight LCD conductivity meter detects the water at any time and accurately and intuitively displays the water quality; 4. The use of adjustable pressure RO silent booster pump (provided CE certification), can run continuously for more than 10,000 hours; 5. Built-in WATER large-capacity integrated dual-channel injection pretreatment + purification column system, longer service life; 6. Configure 20L imported vacuum pressure storage tank (certified by NSF) to avoid secondary pollution in contact with air. Technical Parameters: 1. Influent water source: urban tap water, water temperature 1-45 °C, water pressure 0.1-0.5Mpa, TDS <300ppm; 2. Water production: 10L/H, 20L/H, 30L/H, 40L/H (any one of four specifications); 3. Instant water intake: 1.5-2L/min; 4. Effluent water quality: conductivity ≤ 0.2μs/cm @ 25 °C, desalination rate ≥ 99%, water quality is better than GB/T6682-2008 secondary water standards; 5. Power supply: 220V/50Hz, power: 30W-75W, noise ≤ 40 (dB); 6. Host size: length × width × height (420mm × 370mm × 470mm), weight: 25kg; 7. Optional: 1. Raw water pressurization system (optional for original water pressure); 2. Automatic water softener (optional for raw water TDS> 300ppm);
