H2Blue Hydrogen Test Kit 30mL Bottle
This is the 30mL version of the H2Blue eco formula, a reagent (non-ethanol solvent) which can be used to measure the concentration of dissolved H2 gas (mg/L-ppm) in hydrogen-rich water. When the drops are placed into water containing dissolved molecular hydrogen, the blue drops turn clear. One 30mL bottle contains enough reagent to do approximately 150 hydrogen-level measurements. Includes graduated beaker.
