PH90 – Waterproof pH Meter

Rugged waterproof (IP57) housing with Flat Surface Electrode for measuring pH in liquids, semi-solids, and solids. Does not break or get junctions clogged like the traditional glass bulb electrodes. Easy to replace sensor is perfect for field or lab use.

  • Rugged replaceable flat surface pH electrode for quick on-the-spot pH measurements
  • Simultaneous display of pH and Temperature
  • 2 or 3 point calibration automatically recognizes buffer solutions (order pH buffers separately)
  • PTS (percent of slope) tells you when it’s time to replace your electrode (below 70% or above 130%)
  • Automatic Temperature Compensation
  • Data Hold, Min/Max, Auto Power Off, and low battery indication
  • Waterproof design (IP57) floats in water and protects the meter in wet environment
  • Complete with flat surface pH electrode, protective sensor cap, and two 3V CR-2032 button batteries
