【Product overview】

This controller is widely used in thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food and tap water industries. It mainly monitors the PH/ORP and temperature of the solution continuously.

【Features】

● 128*64 dot matrix LCD display, switchable between Chinese and English, stable operation around the clock;

● Simple menu design, easy and convenient operation, graphical prompts, beautiful and clear interface;

● Adjustable software digital filter, enhanced hardware anti-interference ability, making measurement more stable and adaptable to complex industrial environments;

● Universal power supply 100~240VAC, DC 9~36VDC can also be customized;

● RS-485 digital interface, MODBUS - RTU communication protocol;

● Two measurement functions PH (acidity) measurement or ORP (oxidation-reduction potential) measurement;

● With metal antimony electrode function, it can be used in hydrofluoric acid environment.

【 Controller installation】

Product installation diagram

Open a 92.5×92.5mm (positive tolerance) hole in the product cabinet or installation panel.

It is recommended to use 0.5 to 1 square wire for the power cord, pass it through the waterproof cable head in the middle, and leave a certain length margin.
