pH/ORP control type
Pump set


It is a price-worthy set in which a pump is incorporated into an outdoor type  pH meter/ORP meter with control functions, which has been developed for the first time in the industry.  Since no large-scale site work such as that for a control panel and wiring is required, it can be installed at low cost.

Advantages Applications Specifications

・The automatic control method can be chosen among 3 types.  (ON/OFF; time division proportional; twin timer)

・A price-worthy set incorporating a diaphragm type metering pump.

・The lineup includes 2 types of pumps having a different discharge capacity.


・pH neutralization or oxidation/reduction treatment of drainage in the chemical industry, etc.
・Incorporation of the apparatus of each process.
・pH measurement and control in hydroponic culture, etc.
・pH measurement and control of drainage from cleaning.
・pH measurement and control for drainage from experiments, etc.
