Industrial ORP meter HO-480

Industrial ORP meter HO-480

Overview

The HO-480 industrial ORP meter is an ORP converter for measuring the oxidation-reduction potential of all types of solvent.
Being combined with a lead-free sensor, it makes measurements in a way that is kind to the environment.

Features

  • Includes a sensitivity correction function
    It is possible to compensate for changes in the sensitivity of the ORP electrodes.
  • A line-up of lead-free ORP electrodes
    Not only the glass body, but almost all sections of the ORP electrodes, including lead wires and soldered junctions are lead free.
  • Uses lead-free solder
    To reduce the burden on the environment, lead-free solder has been used to mount the components on the printed circuit board.
