Instructions Manual:
1. Fill sample water up to 6ml mark in container provided.
2. Add a drop of tester to sample water and swirl gently to mix well. If dissolved hydrogen is detected.
3. Continue to add the tester drop by drop and swirl gently every few drops to mix well. Maximum dissolved hydrogen concentration reach when sample water turns blue.
4. Record the number of drops which made by transparency turn blue.
5. 1 drop of tester reaches with approximately 100ppb of dissolved hydrogen.
6. Add up number of drops to calculate dissolved hydrogen concentration.
HOW TO CALCULATE TOTAL DISSOLVED HYDROGEN CONCENTRATION?
EXAMPLE: 10 DROPS OF TESTER WITH SAMPLE WATER STAYING TRANSPARENT EQUAL TO 1PPM OF TOTAL DISSOLVED HYDROGEN.
