Name: Water ORP and pH meter
Cost: around $150
Intended use
Water ORP and pH meter is used to measure water oxidation-reduction potential (ORP) and pH. The intended use of the device is to
- measure water ORP
- measure water pH
- ensure that water has optimum sanitizing value and quality for the birds
- identifying water supplies that do not have an adequate chlorine residual
- adjusting the residual without overusing chlorine
How does it work?
The ORP and pH meter consists of electrodes that are used as a probe or sensor to measure the redox potential and pH of water. Adding oxidizing agents (e.g. chlorine) to water increases ORP reading.
Standard ORP and pH measures for poultry water
- ORP > 650 mV (acceptable)
- ORP = 700 to 750 mV (most desirable)
- Lower values of ORP (e.g., 250 mV) represents a heavy organic load or the presence of reducing agents such as ferrous iron (Fe2+), manganese (Mn2+), bisulfide (HS-), and sulfite.
- The most effective range of pH for water sanitizers is between 5.5 to 7.
Using the device
To use the ORP and pH meter, take the electrode cap off and turn the device on. Insert the electrodes in the water sample and gently stir. Once the measurement reading stabilizes, read the measurement for both ORP and pH.
One Response
Thank you for the info Dr Mohammad Afrouziyeh, A really useful and sensitive tool, we use so much in Poultry farms at caribbean coast region, where level of Chlorine is affected due to Fe2+, Manganese, Sulfite and Salts.
