Dual Channel Voltmeter Kit

Dual channel voltmeter measures voltage from 0V up to 70V providing excellent reading accuracy and 100mV resolution. It has two input channels for measuring two voltage sources at the same time. Dual channel voltmeter kit uses PIC16F876A microcontroller with built-in ADC (Analog to Digital Converter) and 16 x 2 backlighted LCD display.



Kit comes with all components required to build high quality dual channel voltmeter kit including premium quality PCB. Voltmeter can also measure AC voltage if full bridge rectifier is added to voltage input. Dual channel voltmeter can both measure and be supplied by the same power source.
