Precision pH meter analog front end, typical bias current with ultra-high input impedance 25fA, with analog and digital modes. The voltage of-500mV can be measured in analog mode, and the zero point (7.000ph) and 0 or 14ph can be adjusted by potentiometer.The measuring range is 0-14ph. The output voltage 0mV represents 0, and 1400mV represents 14. It can be displayed directly by connecting the voltmeter.You can switch to the digital acquisition mode through two switches, that is, you can use the adc to collect data, and the range can beTo-2ph -19ph can be stabilized to 4 or 3 decimal places by filteringThe test board comes with a reference of up to 3ppm, which can provide a reference voltage reference for 24-bit high-precision ADCs with a noise of 4uVpp.
