PPB Dissolved Oxygen Testing

CHEMetrics PPB Dissolved Oxygen visual test is ASTM's primary reference standard for detecting dissolved oxygen (DO) in water for boiler applications and power plant operations, with sensitivity down to 2 ppb, with no false negatives and no instrument calibration.

Each low range DO 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.

Purge the system
using the special sampling tube
attached to water source

Snap the ampoule
by placing the tip at the bottom
of the sampling tube

Obtain test results
by viewing the test ampoule and
colour comparator from the bottom
