HO-480

Panel-mount Type ORP Meter (Four-Wire Transmission)

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.

Measuring range

0 - ±2000 mV

Segment: Process And Environmental

Division: Process Water

Manufacturing Company: HORIBA Advanced Techno Co., Ltd.

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.
