13 – Optional accessory: Hydrogen measuring drops
Testing the amount of molecular hydrogen is carried out immediately after production with the
optional H2 Blue® Kit.
A water sample of 6 ml is filled carefully into the measuring cup and one drop of the blue measuring
liquid is added. To obtain the same size of drops it is recommended to keep the bottle vertical.
Each
drop that discolours means 0,1 ppm (=100 ppb) dissolved hydrogen gas.
If a drop does not discolour automatically one can stir gently.
If the liquid still does not discolour, then the last drop does not count. Water under normal air pressure
can contain up to 1,6 ppm hydrogen gas (full saturation). From chemicals or with the
Aquacentrum
BLUE 900
®
Hydrogen Generator
you can also produce an over saturated water with more than 6 ppm.
Yet this falls back to full saturation after a few minutes when this water comes into contact with the
normal atmosphere. Whoever wants a lot of hydrogen, has to drink quickly or fill the container to the
brim so that it is gas-tight and bubble free.
Do not drink the test liquid and keep it out of reach of children! Use protective gloves, a surface that
can be wiped clean and watch out for clothing or dishcloths. The drops contain methylene blue, a
very intense dye.
