This analog isolator is designed to work exclusively with our Gravity line of low-cost embedded meters. Electrical 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 a PWM 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.
