Rapid Dissolved Oxygen Analyzer

The rapid dissolved oxygen meter isolates the measured liquid through an electrode membrane, allowing oxygen molecules to pass through the membrane and undergo a reduction reaction with the electrode, generating a current. The current intensity is proportional to the dissolved oxygen concentration. It is used for on-site detection of oxygen content in water bodies and monitoring dissolved oxygen changes in wastewater treatment and aquaculture.
Selection
Choose between portable or online types based on the measurement environment; ensure the measurement range covers actual needs; electrodes require regular replacement of membrane caps and electrolyte; check if the instrument calibration method is simple; match the protection level to the usage scenario; select brands with stable supply of consumables.
