Gravity™ Analog Isolator

Article number: Part # #GRV-ISO
Availability: In stock (16)

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.

Data output 12.4KHz PWM
Voltage input 3.0V − 5.0V
Connector Header pins
Current consumption 5V – 23 mA
3.3V – 15.7 mA
Carrier Board dimensions 42mm x 32mm (2.2″ x 1.2″)
Weight 13 grams
