Description

Zero oxygen solution set hanna hi7040l 

HI-7040L is a bicomponent zero oxygen solution designed for calibrating both polarographic and galvanic dissolved oxygen sensors. 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.
