Backed by our commitment to accurate and precise measurement, Ohaus Starter Dissolved Oxygen Electrodes are designed to produce exact results time and time again, and can be used in combination with Starter portable DO meters.
Ohaus Starter DO electrodes are galvanic and produce their own electric current. Hence, they are active at all times and do not need to polarize (warm up) before calibration or measurement.
DO probes should be calibrated before being placed in the sample. Before calibrating a probe, do not forget to remove water droplets from the membrane by gently shaking the sensor.
