Central Boiler Water Test Kit

The Central Boiler MolyArmor water test kit gives you a simple method for checking both molybdate concentration and pH.

Both measurements are important when maintaining water treated with MolyArmor 350 Corrosion Inhibitor.

The supplied instructions specify maintaining a MolyArmor-treated system at a minimum of 350 ppm.

Always follow the current Central Boiler water-treatment and testing instructions for your furnace.

Easy 4-Step pH and Molybdate Test

1. Dip the Test Strip

Dip one test strip into the water sample for 1 second, then remove it.

2. Shake Off Excess Water

Shake off excess liquid.

This is important because excess water can bleed from one test pad to the other and affect the reading.

3. Check the Molybdate Reading

Compare the molybdate test pad to the supplied color chart within 10 seconds.

4. Check the pH Reading

Compare the pH test pad to the supplied color chart at 30 seconds.

  • 25 MolyArmor test strips
