Boiler & Cooling Water Test Kit
Test kit for boiler and cooling water: Nitrite, Chloride, P-Alkalinity and pH tests for marine systems
-
Some reagents required for tests shown in this booklet are classed as hazardous and as such, a minimum protection of gloves (rubber or plastic) and safety goggles/spectacles or facemask MUST BE WORN.
In addition please note and observe the Risk and Safety phrases on each reagent container and follow handling guidelines as instructed.
GENERAL NOTES
- Avoid contact with skin or eyes
- In case of contact with skin or eyes rinse immediately with plenty of running tap water, and seek medical attention
- Seek attention if irritation persists
- In case of ingestion, wash the mouth out thoroughly with water, try to vomit and seek medical attention
-
P-Alkalinity
-
Take 20 ml of cold coolingwater sample with the 20 ml syringe. Spray the 20 ml in the clean test jar.
-
Add 4 drops of Reagent PA1. The sample will turn pink. In case the sample does not colour pink, the reading is zero.
-
Add drop by drop Reagent PA2, until the sample decolours. Count the numbers of drops used.
-
Each drop is equivalent to 40 mg/l or ppm P-Alkalinity expressed as CaCO3
-
Retain the sample after the alkalinity test, as this sample can be used for the Chloride test.

Chloride Test
-
Take 20 ml of cold coolingwater sample with the 20 ml syringe. Spray the 20 ml in the clean test jar.
-
Add 12 drops of Reagent BC1. The sample will turn orange/yellow.
-
Add drop by drop Reagent BC2, until a turbid dark orange to brown colour appears. Count the numbers of drops used.
-
Each drop is equivalent to 20 mg/l or ppm Chlorides

After refreshing, repeat the Nitrite test. 7 140 8 160 9 180 10 200 11 220 12 240 13 260 14 280 15 300 ⇒ 1 mg/l is 1 ppm 16 320 17 340 18 360 19 380 20 400 Nitrite Test
-
Take 0,5 ml of cold coolingwater sample with the 2,5 ml syringe. Spray the 0,5 ml in the clean small test tube.
-
Add 4 drops of Reagent N1. The sample will turn dark orange/red.
-
Add drop by drop Reagent N2, until a pale blue colour appears. Count the numbers of drops used.
-
Each drop is equivalent to 200 mg/l or ppm Nitrite (NO2-)

Maximum Chloride levels:
⇒ LT Systems : 100 mg/l
⇒ HT Systems : 50 mg/lIn case of too low Nitrite level dose Caretreat 2 Diesel. 1 liters per m3 gives 250 mg/l NO2-.
In case of too high Nitrite level partly refresh the coolingwater with demineralized or evaporated water. After refreshing, repeat the Nitrite test.
