PH/Ration Control Training Equipment Didactic Equipment Mechatronics Trainer

1 Product overview

1.1 Overview

This pH process control system is based on pH adjust trainer, it’s used for pH

control teaching. Through relative operation, students will be familiar with pH

station control principle and control method, to cultivate students corresponding

knowledge and technical skills, it’s suimeter for engineering university, college,

technical schools, training institute.

1.2 Feature

（1）Control monitor system is with good test technology capacity, can simulate  industrial boiler water quality testing requirement, can real time, accurately test boiler water pH value（it means boiler water quality）condition. 

（2）According to the industry standard requirement on boiler water quality PH value, real time automatically test, accurate data collection, delivery to training workbench center in time, set observe and control CPU control signal, make observe and control CPU add water, add acid, alkalify and pollution discharge.

（3）Through this training system, to learn students to understand boiler water acid, learn through on/off, or control injection to control ration, to learn to control Ph value, through manual control acidification and alkalify value to adjust PH value, learn three control method of PH value control.
