This Replacement ORP Probe connects directly into the input terminal of a ORP meter, ORP controller or any ORP device that has a BNC input terminal.  This OPR Probe precisely determines the redox tension of the intended solution to be measured.  Cable length is 90cm.  Fit for measuring drinking, domestic and rainwater, aquariums, tanks, ponds, pools, spas, etc.

What is ORP

ORP (Oxidation-reduction potential) measures the ability of bacteria to breakdown or decompose waist and contaminants. ORP depends on the amount of disolved oxygen and other elements in the water so when the OPR is high, there is lots of oxygen present in the water which means the bacteria works more efficiently.

Though not technically correct, oxygen and other elements that contribute to high ORP will effectively help ‘eat’ things that you do not want in the water. When ORP is low, dissolved oxygen is low, which means toxicity of certain metals and contaminants can increase. If there is lots of dead and decaying material in the water that cannot be cleared or decomposed efficiently, your OPR will likely be low and this is obviously not a healthy environment for fish.  In healthy waters, ORP should read high between 300 and 500
