Calkit-O₂

Calibrate in the lab or in the field

The oxygen microsensor or oxygen MicroOptodes are calibrated by a 2-point calibration and the second calibration point, the high calibration point, is performed using our CAL300 calibration chamber.

The buffer contains a slightly alkaline ascorbate ensuring a trustworthy zero-oxygen reading for your daily calibration routine – both in the lab and in the field.
