PHG-206 industrial PH meter Features:
High intelligence: PHG - 206 intelligent online PH meter with high precision AD conversion and single-chip microprocessor technology, can finish the PH value, temperature measurement, temperature automatic compensation, self-inspection of instrument, and other functions.
Using the latest device, strong anti-jamming capability, high impedance input impedance is as high as 1012 Ω; Current output using photoelectric coupling isolation technique, strong anti-interference ability, realize remote transmission. Has the good electromagnetic compatibility.
High protection grade: waterproof and dustproof design, suitable for outdoor use (protection grade: IP65).
25 ℃ conversion: pure water and ammonia ultrapure water for the benchmark 25 ℃ temperature conversion, realize the PH value of the display at 25 ℃, is particularly suitable for power plant a variety of water quality measurement.
Showed that simultaneously in a screen at the same time show the PH and temperature. Using high brightness LED display module, the main display 10 x 10 mm with red PH value, eye-catching and visual distance.

A pH meter is an instrument used to determine the pH value of a solution. pH meter is a common analytical instrument widely used in agriculture, environmental protection and industry. Soil pH is one of the important basic properties of soil. Factors such as the temperature of the solution to be tested and the ionic strength should be considered during the pH measurement.
