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.
