Accessories for Hanna pH and dissolved oxygen meters.

A high quality, bi-component zero oxygen solution made from reagent grade chemicals. Hanna dissolved oxygen solutions have the lot number and expiry date clearly marked on the label and are air tight with a tamper-proof seal to ensure the quality of the solution. By simply immersing the dissolved oxygen probe in the solution users can quickly calibrate to 0% oxygen concentration, allowing for accurate follow-up measurements of dissolved oxygen in the sample. Hanna dissolved oxygen solutions are produced using reagent grade chemicals in a temperature controlled environment.
