The Gravity™ Analog Isolator is designed to work exclusively with our Gravity line of low-cost embedded meters. These isolators remove all electrical interference coming from other probes or pumps in the same water you are testing.

It converts the analog output from a Gravity pH, Gravity ORP, or Gravity D.O. meter to both, a PWM and a voltage signal.

The PWM signal can then be easily converted back to a noise-free reading. Because this isolator uses PWM, it can be connected to a microcontroller that does not have an ADC, such as a Raspberry Pi.

The voltage signal converts the sensor value into 0 – 3 Volts, good for a micro-controller that does have an ADC.

*A Raspberry Pi cannot accurately read PWM or analog voltage without a 3rd party hat.
