What is it?

CaliSense: USB AC/DC current sensor

Non Invasive no load during measurement

Why did you make it?

Other current meters have sense resistors which go inside circuit which is error prone and sometimes dangerous. In addition they have no data logging capability.

What makes it special?

Senses current without placing resistor in circuit Safe to use Measures up to 100A with an accuracy of .1A Current logged and saved to Laptop, Tablet or Smartphone Specially designed for ebikes and EV’s. All data logged to USB port. USB terminal software saves measured data to file
