Supplier's note

  1. Technical Breakthroughs:

    • Automatic Temperature Compensation (ATC): Ensures pH readings remain accurate even in fluctuating water temperatures.
    • CE Certification: Guarantees compliance with EU safety and performance standards for laboratory-grade reliability.
    • 3-Point pH Calibration: Reduces errors in harsh environments like industrial wastewater.

  2. Optimal Version Selection:

    • Base Model: Ideal for home users or basic applications (e.g., aquariums) where cost-efficiency is key.
    • Advanced Model: Targets professionals needing extended battery life and wider TDS/EC ranges (e.g., agriculture, water treatment).
    • Pro Model: Designed for research labs or industrial settings requiring ±1% accuracy and premium ATC for critical analyses.

With the Pro Model’s ±1% accuracy, you can detect trace contaminants in pharmaceutical-grade water. Its enhanced ATC paired with a 30,000 ppm TDS range ensures reliability in extreme conditions, such as chemical plant effluent testing. For casual users, the Base Model’s affordability and portability make it perfect for weekend pool maintenance.
