Analog Isolator

$ 16.16

This analog isolator is designed to work exclusively with the analog line of low-cost embedded meters by Atlas Scientific. 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 an analog 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.

*A Raspberry Pi cannot accurately read PWM.
