■ Product Description

PH/ORP-9900 pH/Redox Potential Transmitter Controller is a general-purpose, cost-effective online monitoring instrument, which can be equipped with a variety of specifications of two or three composite PH electrodes or ORP electrodes, the whole machine has the characteristics of high measurement accuracy, anti-interference, easy installation and simple operation.

● Enlarged LCD display, multiple parameters can be displayed on the same screen;

● PH supports dual-mode three-point calibration, in line with international standards, 4.00 /6.86 /9.18 or 4.01 /7.00 /10.00;

● PH supports offline calibration and online calibration;

● Support manual correction of measured values; (Manual compensation via PH0 or ORP0)

● 4~20mA output current, support instrument/transmitter dual mode, meet the interface of all (4~20)mA receiving units;

● Dual relay output control, and delay control, to meet the pH or ORP range control and adjustment, can be easily connected with the dosing pump;

Measuring principle

When the electrode is immersed in the solution, the H+ charge acts on the sensor, resulting in a slight voltage change, and the value of the change is transmitted to the transmitter through the cable, and the transmitter converts, calculates, and displays the measured pH/ORP and temperature signals.

Areas of use

This series of instruments is suitable for environmental protection engineering, water treatment and purification, industrial process monitoring, aquaculture, and other industries in the pH/ORP online monitoring.
