ppb Dissolved Oxygen Testing
CHEMetrics ppb D.O. visual test is ASTM's primary reference standard for detecting dissolved oxygen 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 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.
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
