Oxygen Meter and Sensors      
Our oxygen measuring system utilizes the latest technologies in electronic circuitry and chemical sensors. The 2 mm stainless steel-tip electrode can be used to measure oxygen in liquid solution or gas phase. The meter can display current, percentage, or ppm Oxygen. The meter offers an activation function to restore the activity of the sensor without the need of polishing and conditioning.
