PLATINUM ORP ELECTRODES

An ORP sensor must be chemically inert; it cannot be oxidized or reduced itself. It must also have the appropriate surface characteristics to promote rapid electron exchange, a property known as high exchange current density. Two precious metals have been shown to work well for this purpose: pure platinum and pure gold are both used in the making of ORP sensors.

AUTOMATIC TEMPERATURE COMPENSATION

HI98121 has a built-in temperature sensor allowing for automatic temperature compensation of pH and ORP measurements.

SUPPLIED COMPLETE SET

The HI98121 meter is supplied complete with no additional purchase required.

– pH, ORP and temperature electrodes

– Standard solution package pH4.01 and 7.01

– Package dORP 470mV standard solution

– Package dElectrode cleaning solution after measurement

– Package dpH electrode storage solution
