dvr Cooling Water Test kit RXSOL 309

REAGENT:-NITRITE, CHLORIDE , pH, ALKALINITY

Application:

Procdure:-

NITRITE PROCEDURE for test ( STEP WISE ):

  1. Measure 1 ml of SAMPLE WATER in graduated TEST TUBE / CYLINDER , with the help of syringe / pippet and diluted with Distilled Water up to 10 ml.
  2. Add 1-2 drops of  RXSOL TK5 and mix with the stirring rod , to obtain ORANGE / light reddish  colour. 
  3. Add RXSOL TK6  drop by drop , mixing with the stirring rod until  For endpoint ORANGE to BLUE / GREENISH colour just appears / develop. 
     

Each DROPS is equivalent to 50 PPM of NO2

CALCULATION :-50 X Number of DROPS of TK6

CHLORIDE PROCEDURE for test ( STEP WISE ):-

  1. Measure 15 ml of SAMPLE WATER in graduated TEST TUBE / CYLINDER
  2. Add 1-2 drops of  RXSOL TK1 and mix with the stirring rod , If  sample turns red / PINK then follows 3rd step otherwise if sample remains colourless proceed to step 4.
  3. Add RXSOL TK2  drop by drop , mixing with the stirring rod until colour just disappears.
  4. Add 3 drops of RXSOL TK3 and mix with stirring rod , the sample will turn YELLOW.
  5. AddRXSOL TK4 carefully by counting drop by drop and mixing throughly until a light reddish / pink / brown colour develop.

RESULT :- Each DROPS is equivalent to 8 PPM of CHLORIDES .

PROCEDURE for TOTAL ALKALINITY:-

Measure 10 ml of SAMPLE WATER in graduated TEST TUBE / CYLINDER

Add 1-2 drops of  RXSOL TK7 and mix with the stirring rod , If  sample turns red / PINK ( which indicates presence of p-Alkalinity ) then follows 3rd step otherwise if sample remains colourless ( Record p-Alkalinity = 0 ) then proceed to STEP- 4.

Add RXSOL TK9  drop by drop ( by counting ) , mixing with the stirring rod until colour just disappears. Each drop is equivalent to 15 ppm of p-Alkalinity , expressed as CaCO3

Add 2-3 drops of RXSOL TK8 and mix with stirring rod , the sample will turn to BLUISH-GREEN .

AddRXSOL TK9 carefully by counting drop by drop and mixing throughly until a light reddish ( salmon ) pink  colour develop.

RESULT:-Each DROPS is equivalent to 25 PPM of Alkalinity
