PH / ORP-Controller-6109

pH/ORP(6109) is a kind of precise instruments used for test and control pH/ORP. It could store, calculate and compensate all the parameters related to testing pH/ORP value, such as the temperature characteristic of pH electrode, the slope deviation of pH/ORP electrode, etc. It has the merits of complete functions, stable performance and simple operation, which makes it as the choice for the enterprises to test and control pH/ORP. PH/ORP serial instruments are equipped with LCD display with back light, the error display, automatic temperature compensation function, colon standardizing function, separated 4-20mA current output, the double-group relay control, high-&-low-point warning display and signal output control, automatic setting of retardation and power-down memory, which makes the backup cell unnecessary, and the information in the instruments kept for over 10 years. pH/ORP serial instruments could be equipped with various kinds of pH electrodes (especially those with HF media and stibium mode).
