HO-480

Panel-mount type ORP meter

A compact water quality meter that offers a wide range of features and functionality.

Suitable for managing neutralization reaction processes such as aeration tanks and denitrification tanks. We offer a wide range of cleaning devices to accommodate a variety of samples.

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

Comprehensive range of cleaning devices.

The ultrasonic cleaner can be retrofitted to HO-480 sites that are not equipped with a cleaner.   *If other cleaners are to be used, sequence control by the customer is required.
