Fast And Safe Logistics
Reliable Quality, Guaranteed Performance.
Compatible with solution‑grounded electrodes, effectively eliminates ground‑loop interference and ensures stable pH measurement under complex on‑site conditions.
Automatically converts measured pH value to the standard 25 °C reference condition for consistent and comparable data output.
Supports flexible selection of 3‑point or 5‑point calibration to optimize measuring accuracy across the full pH range.
The APX2‑G4 high-precision online pH/ORP analyzer is engineered for complex industrial water environments with electric interference and temperature fluctuations. Supporting grounded electrode connection effectively eliminates ground-loop interference for stable measurement in harsh industrial conditions. Built-in 25℃ temperature conversion ensures standardized and comparable monitoring data. Optional 3-point or 5-point calibration optimizes full-range accuracy. Widely applied in municipal wastewater treatment, industrial process water, environmental discharge monitoring, circulating water systems and fine chemical water quality control, delivering accurate, stable and traceable data for industrial automation and environmental compliance.
