Supplier's note

  1. Three Technical Breakthroughs:

    • Ultra-precise ±0.01 pH accuracy (vs. industry-standard ±0.02) enables reliable calibration in high-stakes labs.
    • Extended temperature stability (Pro Model’s 10–40°C range) outperforms traditional 25°C-only solutions, reducing the need for climate-controlled environments.
    • FDA-certified Pro Model meets stringent regulatory requirements for pharmaceutical and medical applications.
  2. Optimal Version Selection:

    • Base Model: Ideal for educational labs or basic quality control where cost-efficiency is prioritized.
    • Advanced Model: Best for research institutions needing ISO-compliant precision without extreme temperature demands.
    • Pro Model: Suited for pharmaceutical or industrial settings requiring FDA compliance, long shelf life, and broad temperature adaptability.

With its ±0.02 tolerance, the Base Model ensures consistency in routine measurements. The Pro Model’s triple-certification and expanded temperature range, however, unlock use in extreme environments (e.g., field testing), while its 24-month shelf life reduces frequent reordering. Pair the Advanced Model’s ISO 17025 compliance with its ±0.01 accuracy to achieve ISO-standardized results in academic research.
