PH/ORP-8851 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.
