Ohaus 30038553 STORP2 ORP Electrode with Cable 1.1 m, Range -1000 - 1000 mV, Shaft Material Glass

Features:

• Basic Principle of ORP
  • Oxidation-Reduction Potential
  • An (ORP) electrode tests for the overall availability of electrons in a medium, specifically the ratio of positive and negative ions in the solution.
  • It is also sometimes referred to as a Redox electrode.
  • ORP is the only practical method used to electronically monitor sanitizer effectiveness, and it is also commonly tested in water, such as in a swimming pool and an aquarium. ORP is expressed in millivolts (mV). -1000 mV to 1000mV is a common range for an ORP test. The pH value influences the ORP value significantly.
• Care and Maintenance
  • To ensure an accurate measurement, it is important to keep the electrode clean. Contamination can cause an inaccurate result and a slow response time.

Applications

• pH measurements of environmental and laboratory samples
  • Standard Aqueous samples, general purpose (e.g. pH buffers)
  • Waste water
  • River/lake water
  • Tap water/drink water (partially fit for this application)
