Excellent anti-corrosion performance has been realized by employing CFRPP.Being miniaturized and light in weight, carrying it and its maintenance are easy.

Salinity concentration meter
CM-81S

This unit can measure the salt concentration and control the pump, etc.

The salinity can be displayed as a percentage on a large display that is easy to see in the field.

The pump can be controlled by inputting an arbitrary set value.

Advantages

・The measured salinity is displayed on a large LCD display.

・The LCD with a large backlight displays the measured salt concentration, liquid temperature,

lower limit set value, and output status.

・The presence or absence of control can be controlled by an external input signal.

・Alarm setting values can be easily changed and measured density values can be easily corrected.

・The power supply is free from AC100 to 240V.

Applications

・Management of salt concentration in the cultivation of seaweed.

・Charvet ice salinity control.

・Management of salt concentration in plant cultivation.

・Management of salt concentration in washing water and ice making in the fishery industry.

・Measurement of salt concentration in soil.

・Control of salt concentration of washing water in food processing.
