Test 77 LANGELIER WATER BALANCE

To determine Water Balance Index using the Pooltest 25 Premier, five tests
must be performed and the data used in the Water balance test program :
Alkalinity (Alkaphot), Calcium Hardness (Calcicol), pH (Phenol Red), TDS

and temperature tests are also required. Prepare the test solutions and

proceed as follows :-

1

Select Test 77 by pressing the Alkalinity key (no. 7) twice.

2

Carry out the Alkalinity test then select ‘Follow on’ from the ‘options

menu’ on the results screen.

3

Carry out the Calcium hardness test then select ‘Follow-on’ from the ‘options

menu’ on the results screen.

4

Carry out the pH test then select ‘Follow-on’ from the ‘options menu’ on

the results screen.

5

Manually enter the TDS reading (in mg/l or ppm) taken using the

numbers displayed on the keypad. Select ‘OK’ when the figure on screen

is correct.

6

Manually enter the temperature using the numbers displayed on the

keypad and select ‘OK’.

7

The Langelier Index is calculated and is displayed. Consult the chart overleaf

for guidance.

NOTE:

If any of the tests are out of range, the procedure is ended. If an

incorrect reading is taken part-way through the procedure, insert the correct

tube then select ‘Read’. The new reading will replace the former incorrect
value in the Water Balance Calculation :
