Measuring PPB Dissolved Oxygen in Boiler Water

The most reliable ppb D.O. test is also the simplest.

CHEMetrics' ppb D.O. visual test is ASTM's primary reference standard for measuring and testing dissolved oxygen in water.  With sensitivity down to 2 ppb, Dissolved Oxygen CHEMets® ampoules provide power plant operators with a rapid, reliable means to determine ppb levels of Dissolved Oxygen.

Each low range D.O. kit includes a special sampling tube that allows the user to break the tip of the ampoule in a flowing sample stream in order to preclude error from contamination by atmospheric oxygen.
