HE-480C

Panel-mount type conductivity meter (conductivity meter)

For control of pure water and boiler water, as well as monitoring wastewater treatment.

Playing an active role in the control of pure water and boiler water as well as monitoring wastewater treatment. A lineup of sensors that are suitable for various sample characteristics are offered. The use of panel-mounted transmitters allows for cost savings at the time of installation.

COND

Division: Process Water
Manufacturing Company: HORIBA Advanced Techno Co., Ltd.

Diverse lineup of sensors available

Two types of sensors are available: a lead type which can be directly thrown into the tank or placed in the tank with an immersion holder, and a connector type for direct insertion into piping or with a flow-through holder. Materials that can accommodate special water applications are also offered.

Possible to be used in a panel-mounted configuration

This transmitter is easy to install while providing standard functions.
