Item Code: RXSOL-62-5519

1) Hardness Test Kit for BOILER :
This test measures the amount of soluble calcium and magnesium ions in a mud filtrate. When measured simultaneously, the result is called total hardness. The calcium ion concentration can be determined separately and when it is subtracted from the total hardness, the magnesium ion concentration can then be determined. Different buffer-indicator combinations may be used for these determinations. It is imperative however not to intermix the various buffers and indicators.Application : Direction For use :

1. Take 25 ml of water sample to be tested in the Test jar
2. Add 1 micro spoon full of Reagent RX-TH-1.
3. Mix contents well to dissolve.
4. Add 15 drops of Reagent RX-TH-2 and mix well.
5. If colour turns blue, it indicates there is no hardness in the water.
6. If colour turns red, it indicates there is hardness.
7. Now drop wise add Reagent RX-TH-3 , counting the number of drops while Mixing until the colour changes from RED to BLUE.
Reagent RX-TH-4 instead of Reagent RX-TH-3
Calculation :
Hardness PPM = RX-TH-3 Number of Drop X 2
Hardness PPM = RX-TH-4 Number of Drop X 5
Part No.: RXSOL-62-5505-001

2) Hydrazine Test Kit Colorimetric Procedure

Colorimetric Procedure

The objective is to maintain a hydrazine residual between 0.05-0.2 ppm depending on operating pressure and boiler designe. Actual consumption is determined under operating conditions. A normal dosage is approximately 1 ltr. per day, depending of system layout.

Hydrazine is a convenient reductant because the by-products are typically nitrogen gas and water. Thus, it is used as an ANTIOXIDANT, an oxygen scavenger, and a corrosion inhibitor in water boilers and heating systems.

Hydrazine is mainly used as a foaming agent in preparing polymer foams.

No oxygen is entering the boiler with the feed water when hydrazine is present in the water.

Directions for use : Based on Colorimetric Procedure
1. Take 5 ml of sample to be tested in the Test jar.
2. Add 40 drop (2ml) of Reagent TK-HZ1. Mix wel
3. Add 2 micro spoon full of Reagent TK-HZ2. Mix well upto provider dissolves Completely. Wait for 10 minutes.
4. Now rinse the empty comparator tobe with above solution and will upto the half level of the comparator tube.
5. Insert this tube in sample slot of comparator.
6. Compare the developed colour with standard comparator colours.
7. Note down the ppm level of Hydrazine as N2H4

Note 1 ::: Studies showed that hydrazine was not stable on the sampling device, therefore, immediate extraction of samples after collection was recommended.

Note 2 ::: color is stable for 1 hours.

Sample of Hydrazine is Harmful. Handle with due care.

All open chemicals should be used only in a fume hood.

Avoid any skin contact with all chemicals. Immediately flush contaminated areas with copious amounts of water.

Wear safety glasses at all times.

Always try to keep HYDRAZINE level at minimum level. As by the decomposition of hydrazine ammonia will be liberated and Ammonia in the presence of oxygen is corrosive to copper and copper alloys.

It will be necessary to test the hydrazine residuals in the boiler daily in order to obtain complete protection with minimum doses of hydrazine. If the hydrazine residual in the boiler is over 0.1 PPM, reduce the dosage of hydrazine until the boiler hydrazine residual falls below the recommended maximum of 0.1 PPM. If the hydrazine residual does not immediately drop below the 0.1 PPM level, the boiler should be blowdown to reduce the hydrazine level. New boilers, or those recently open for inspection and repair, may take several weeks to achieve a normal boiler hydrazine residual due to oxides.
