PH / ORP Meters

pH Meters measure the acidity or alkalinity of liquids. Most of them have a special probe connected that measures the pH and a screen that displays the information. The probe is usually made of glass. These meters range from simple devices to complex systems.

ORP Meters, Oxidation-reduction potential, measures the degree to which a substance is capable of oxidizing or reducing another substance. ORP is measured in millivolts (mV). A positive ORP reading indicates that a substance is an oxidizing agent. A negative ORP reading indicates that a substance is a reducing agent.
 
pH Meter Applications
  • Agriculture
  • Fish farming
  • Aquariums
  • Boilers
  • Cooling towers
  • Drinking water
  • Food and Beverage
  • Hydroponics
  • Laboratories
  • Chemical industry
  • Pools/Spas
  • Water treatment
Key Features of pH Meters to Consider
  • RENEW feature that tells you when it’s time to replace your pH electrode
  • CAL feature that tells you when it’s time to recalibrate your meter
  • Flat Surface pH electrode that is completely waterproof and rugged enough to withstand harsh environments
  • Memory stores 15 readings
  • “On-the-Spot” measurements
This video demonstrates the waterproof Extech pH meters and discusses solutions to the top problems users have when using traditional pH meters: 1) clogged junctions, broken bulbs, and limited applications 2) the shelf life of electrodes 3) calibration and 4) recording data.
