High precision and durability Titrant water hardness analysis kit to measure lime in French degrees or ºTH

High precision and durability Titrant water hardness analysis kit to measure lime in French degrees or ºTH. Analysis by colorimetry.

Total water hardness test kit very accurate ±0.5°TH and for a large number of readings. Capable of reading at extremely high hardness.

Before use, read the instructions inside the packaging.

The measurement is very simple:

1.      Fill the test tube with 5 ml of the water to be analyzed.
2.      Add two drops of 15cc hardness indicator reagent and shake, it will turn red if it has lime.
3.      Now add drops of the titration reagent (25cc transparent bottle) and shake the meter with each added drop.
4.      Count the drops introduced until the color turns from red to blue.
5.      The number of drops used indicates the hardness in French degrees; one drop corresponds to a French degree.

Included in the kit:

- 1 hardness testing bottle of 25 cc.

- 1 bottle of 15 cc hardness indicator.

- 1 20cc test tube

Hard water has some drawbacks, such as increased use of soap, scale in the hot water pipe, boilers... white marks on glass, window panes. It is ideal for checking the correct operation of your water softener.
For domestic use, a normal hardness is below 12ºTH.


Between 2 and 5° TH: very low hardness.
Between 5 and 10° TH: low hardness
Between 10 and 15° dH hard water
Between 15 and 25° dH very hard water
More than 25° TH: extremely hard water

This chart allows you to easily know the hardness of your water in a matter of seconds.
0 to 80°F or TH: Measurement range. 1 drop = 1 F = 1 TH.
Accuracy: ±0.5°TH.
