Required Equipment
1.Thermo Scientific Orion pH/mV meter, such as the
ORP electrodes can be used on any pH/mV meter with a BNC or U.S. standard connection. The electrodes can also be used on meters with a variety of inputs when an adapter cable is used. Visit www.thermo.com/water for details.
Refillable ORP Triodes have temperature connectors that are compatible with specific meters, refer to the list below.
2.Thermo Scientific Orion ORP electrode.
•The 9180BNMD and 9179BNMD ORP/ATC Triode electrodes have a temperature connector that is compatible with the Star Series meters.
•The 9180BN and 9179BN ORP/ATC Triode electrode have a temperature connector that is compatible with the A+ Series meters.
3.ORP electrode filling solution. Use Cat. No. 900011 filling solution for samples that have a total ionic strength greater than 0.2 M. Use Cat. No. 900001 filling solution for samples that have a total ionic strength less than 0.2 M.
ORP electrode filling solution is not required if using a 9179BNMD or 9179BN low maintenance ORP/ATC Triode
4.ORP standard, Cat. No. 967901 or 967961.
ORP standard is highly recommended to ensure accurate ORP measurements.
5.Beakers, plastic or glass.
6.Magnetic stirrer or Orion stirrer probe, Cat. No. 096019. The stirrer probe can be used with
7.Distilled or deionized water.
