pH Test Kit - RXSOL-62-5519-001




pH is an important part of the boiler chemical control program .pH is a measure of the acidity or basicity (alkalinity) of water on a scale running from 0 to 14. The neutral point on this scale is pH 7; values below 7 indicate increasing acidity and those from 7 to 14 indicate increasing basicity.

A major element of boiler water treatment is controlling corrosion by keeping the boiler water pH slightly alkaline. This is done by feeding sodium hydroxide and sodium phosphate salts in carefully controlled quantities. This Alkaline pH gives the dosage of boiler compound to fight against corrosion .In water treatments, overfeeding chemicals can do as much damage as underfeeding, so continuous monitoring of pH is an important part of the boiler chemical control program.

Boiler pH should be kept between 10.5 and 12.5. Below 10.5, there is insufficient protection from corrosion and hardness compounds if they are not precipitated in the desired, free-flowing form. Above 12.5 there is the possibility of caustic embrittlement and carryover.

Direction to use:-

1. First take 5 ml water sample to be tested in the jar.

2. Add 4 drops of pH reagent mix well

3. Now place this test jar on the color card(see back side) match color in the test jar with different printed colors (view from top side vertically downwards)

4. Note down the ph of the sample after color comparison .
