Dissolved Oxygen meters

Oxygen measurement with LDO = 100% confidence

Calibrating oxygen electrodes is history!

Today, there is LDO - the optical dissolved oxygen sensor without drift, without electrolyte, without membrane clogging.

The new measurement principle (LDO stands for Luminescent Dissolved Oxygen) has revolutionised oxygen measurement. Instead of frequent calibration and electrolyte replacement, you simply change the sensor cap once each year.
