ตัวควบคุมค่าพีเอช โออาร์พี รุ่น SUP-pH3.0 แบรนด์ SUPMEA

pH ORP controller 

Features

• SUP-pH3.0 Online pH meter is a multivariable analyzer used for measuring/controlling the pH and ORP with different temperature. 
• The function is switchable on the device itself. 
• Depending on the measured variable, combination electrodes (e. g. pH sensors) or split versions (glass electrodes with a separate reference electrode) can be readily connected.
