HO-200

Field-installation type ORP meter

HORIBA's long-selling water quality meter that excels in both indoor and outdoor applications.

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.

A diverse lineup of cleaning devices are offered.  Particularly, ultrasonic cleaners are advantageous as they do not require water or air, making them convenient for retrofitting existing HO-200 installations on site. The drop-in type of cleaning device, which fits into a holder, offers ease of maintenance.

  • *1:  :The standard for effect on the reading by the electromagnetic field of the radiated radio frequency and by the conducted interference is within the measured ORP value ±15 mV.
  • *2  : When the sensor cable, the transmission cable, or the contact input cable is extended to 30 m or longer, the surge test specified in the EMC directive for CE marking is not applied.

 

Note

An arrester (spark over voltage: 400 V) is implemented for transmission output, contact input, and communication. However, use a most suitable surge absorption element on the connection lines in accordance with the ambient environment, the situation of equipment installed, and the externally connected equipment.
