Dissolved Hydrogen Water Testing Reagent (Blue drops) – 12 ml

This Methylene blue/platinum-based reagent can be used to measure the concentration of dissolved H2 gas (mg/L-ppm) in hydrogen-rich water.
One drop measures 0.10 PPM

About 450 drops in a bottle.

Example: If the water stays blue after 12 drops, you have 1.2 PPM(1200 PPB) of molecular hydrogen dissolved in the water.

• EASY TO USE: Turns the blue drops transparent when hydrogen is present in the water
• 1 BLUE DROP = 0.10 PPM (100 PPB) of dissolved molecular Hydrogen using a 6 ml sample of hydrogen-rich water in the included graduated beaker
• WARNING: Stains skin, clothes, and surfaces; Use soap to clean;
  DO NOT INGEST. KEEP OUT OF REACH OF CHILDREN. DO NOT TEST THE WATER DIRECTLY IN YOUR WATER BOTTLE OR GENERATOR
