SH0069 Engine coolant pH tester
The SH0069 engine antifreeze coolant pH meter is a digital display pH meter that uses a blue backlight, dual row digital display LCD, and can simultaneously display pH value, temperature value, or potential (mV) value.
The engine antifreeze coolant pH tester is an instrument used to measure the pH value of the coolant. The main body is a precision potentiometer. When measuring, the glass electrode and calomel electrode are inserted into the measured solution. Due to the different acidity (hydrogen ion concentration) of the measured solution, different electromotive forces are generated. They are amplified by a DC amplifier, and finally the pH value of the measured solution is indicated by a reading indicator (voltmeter). The acidity meter can be used within the pH range of 0-14.
