Product Description
DescriptionPHG-3081B Industrial pH meter is a new pH analyzer developed by our Company. It is a highly
intelligent on-line continuous monitoring instrument consisting of sensor and secondary meter.
It can be used together with triplex or duplex electrodes to meet various applications. With pure
water and hyperpure water electrode, it can be used to measure the pH value of water with an
electric conductivity less than 3µS/cm (such as chemical supply water, saturated vapor, condensate, etc. ). It can be widely used for continuous pH monitoring of various water in many industries such
as power, chemical engineering, environmental protection, medicine, food, and so on. 
Features？ Highly intelligent: industrial pH meter uses high precision AD conversion and singlechip
micro-processing technology, and has such functions as measuring pH value and temperature, automatic temperature compensation, and self-check of the instrument. ？ High reliability: The components are integrated onto a circuit board, without complex function switches, knobs or potential devices. ？ Double high-resistance inputs: It introduces the latest components, and the impedance of the
double high-resistance inputs is up to 1012Ω, providing high protection against interference. ？ Solution grounding: The interference from ground circuit can be eliminated. ？ Isolated current outputs: It introduces light electric coupling technology, providing high protection against interference and realizing long-distance transmission.
