  • with control functions pH/ORP Indication adjustment meter
pH計/ORP計 PE-11N

pH/ORP meter that can be installed outdoors, of which cost performance was pursued.

Its LCD with a large backlight indicates the measured value of pH/ORP,

control point, control direction, whether there is control or not, current value,
and temperature.
Advantages Applications Specifications

・It enables the current settings to be made at the time of an error or calibration, thus taking

   account of safety.

・The JIS method or USA method can be chosen as the automatic calibration method.
・ON/OFF control, time division proportional control, or twin timer control can be chosen.
・The DC output can be scaled.

・It has drip-proof construction that can also be used outdoors (IP54 or equivalent); it is equipped with

   a sunshade cover.


・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.
