Oakton® zero oxygen standard solution ensures accuracy of your dissolved oxygen meter. For accurate dissolved oxygen blanking, the solution undergoes testing using the Winkler method. Follow all precautions recommended by your electrode manufacturer to ensure acceptable results.
Chemical oxygen scrubbers remove oxygen from the solution to provide fast calibration results. For accurate results, calibrate your dissolved oxygen meters with this standard solution. Manufactured according to the APHA and ASTM formulation using high-purity, oxygen-free water.
