Product Description
EZO Dissolved Oxygen Circuit
EZO-DO EZO Dissolved Oxygen Circuit Description
EZO Dissolved Oxygen circuit is a very sensitive device. This sensitivity is what gives the Dissolved Oxygen circuit its accuracy. This also means that the Dissolved Oxygen circuit is capable of reading micro-voltages that are bleeding into the water from unnatural sources such as pumps, solenoid valves or other probes/sensors.
When electrical noise is interfering with the Dissolved Oxygen readings it is common to see rapidly fluctuating readings or readings that are consistently off. To verify that electrical noise is causing inaccurate readings, place the Dissolved Oxygen probe in a cup of water by itself. The readings should stabilize quickly, confirming that electrical noise was the issue
When reading Dissolved Oxygen and Conductivity together, it is strongly recommended that the EZO™ Dissolved Oxygen circuit is electrically isolated from the EZO™ Conductivity circuit.
