The HYDROKIT® is an effective “Go, No-Go” field test designed to periodically check for free water, which is removed to ppm levels by properly operating filter/ separators, Aquacon®, and monitor vessels. Samples are normally taken downstream of the vessel, but they can also be taken at other points in the fuel distribution system. The HYDROKIT® is a color test that indicates free water content in excess of a specified concentration. The HYDROKIT® is designed for “fail-safe” operation, with false negative readings unlikely. Almost any error in performing the test will indicate the presence of wet fuel. If the sample indicates the presence of excessive water, it is always a good practice to repeat the test on a second sample. For further clarification of free water content, a Karl Fischer titration test should be done.
Sample bottle must be clean.
Take sample DOWNSTREAM of vessel.
Push tube down into needle holder in sample.
After tube fills, shake for 15 seconds. Set upright to allow powder to settle.
Check powder color at two minutes.
If color is the same or darker than FAIL, more than 30* ppm of free water is present.
*(15 ppm of free water in HKxxx-15 tubes.)
