Field-installation Type Dissolved Oxygen Meter (Four-Wire Transmission, Optical Type)

HD-200FL - HORIBA, Ltd.

Optical dissolved oxygen sensor with no electrolyte replacement and rugged membrane.
Highly intelligent, including automatic recognition of membrane properties when replacing the sensor cap.

The HD-200FL is an optical (fluorescent) dissolved oxygen meter suitable for monitoring aeration tanks used for sewage treatment, effluent treatment, and other processes. Compared to conventional membrane polarographic type sensors, there is no need for electrolyte (internal fluid) replacement or warming, up. Characteristics of optical sensors are utilized to realize unequaled, improvement in ease of maintenance and reduction in running costs. Moreover, it features enhanced user-friendliness, with sensor caps that have built-in memory and a membrane replacement notification function.
