Supplier's note

  1. Three Technical Breakthroughs:

    • CE certification ensures compliance with EU safety standards, enabling global deployment.
    • Heat-treated steel jaws (Pro Model) offer 30% higher corrosion resistance than standard steel.
    • Dual-spring lock (Pro Model) provides 15% faster measurements compared to traditional spring mechanisms.

  2. Optimal Version Selection:

    • Base Model: Ideal for small labs or field teams needing basic precision (±0.05mm) at a lower cost.
    • Advanced Model: Suitable for mid-scale construction firms requiring 2x faster measurements and a 50% wider range (0–150mm).
    • Pro Model: Best for industrial clients handling large aggregates (e.g., gravel) or extreme environments, with triple the durability of competitors.

With the Pro Model’s ±0.01mm accuracy, you can ensure compliance with ASTM C136 standards for particle grading. Pair its heat-treated steel jaws with the dual-spring lock to minimize human error in high-volume testing scenarios.
