PCM200‑SO4
PROBEST
PCM200‑SO4 Sulfate Water Quality Online Automatic Monitor operates as follows: at 95°C, a specified volume of water sample is added to barium chromate and heated for digestion. Sulfate ions in the water sample undergo a displacement reaction with barium chromate to form barium sulfate, thereby displacing chromate ions. Subsequently, ammonia water is added to precipitate excess barium chromate. The supernatant is collected for colorimetric analysis. Using ultraviolet spectrophotometry, the absorbance A is measured at 440 nm. The concentration of displaced chromate ions is directly proportional to absorbance A. Sulfate content exhibits a direct proportional relationship with absorbance A.
Equipped with a 10.2‑inch TFT high‑performance embedded integrated touchscreen for clearer display, smoother operation, and more stable performance;
Adopts a proprietary adaptive quantitative device with advanced logic judgment to enhance liquid level detection and improve adaptability to complex water qualities;
Uses imported light sources for high stability and long service life;
Low reagent consumption and independent waste liquid separation and collection, effectively reducing maintenance costs;
Built‑in operation log recording function, capable of storing at least one year of raw data and operational logs;
Comprehensive intelligent alarm system: fault alerts, over‑range warnings, standard exceedance alarms, reagent depletion alerts, etc.;
Automatic data protection upon power failure, with TFT true‑color LCD touchscreen for display and control;
Automatic recovery to normal operation after restart or power restoration;
Real‑time instrument status display (measuring, idle, fault, maintenance, etc.);
Integrated dynamic flow diagrams for intuitive, user‑friendly operation and maintenance.
