LABORATORY TESTS AND CONCLUSIONS
The following are extracts from Independent European Laboratory
Reports where tests were carried out on the CALCLEAR water conditioning
units to European (EU) standards.
Test 1: Hardness test
dH = Degree German Hardness 1dH = 1.25 English Hardness (Clark).
1dH =10mg CaCo3 = 1.25(Clark.)
Unit installed on water supply for 7 day water hardness test. Before
installation hardness of water 7.25( dH. Thirty minutes after installation
reading was 5.75( dH. Other results as follows:

Conclusions:
The hardness of water was reduced from 7.25( dH
to 4.25( dH over a test period. The CALCLEAR unit reduced water hardness
by 41% under test conditions.
Test 2: Turbidity
Shows the amount of Calcium (and /or Magnesium) salts affected by
the unit and "neutralised' i.e made incapable of forming scale.

The boiling vessel used in the trial contained a hard deposit of some
1.3mm calcium salts, accrued over 5 years use of the laboratory water
supply. The CALCLEAR unit reduced depth of limescale from1.3mm to 0.2mm
over a 2 month period. The unit installed and used as per manufacturers
instructions performed well over the test period. It can be said to
perform its main function of removing and preventing limescale in a very
effective way, particularly in light of the test conditions which were
very rigorous. Other effects of the treatment are as claimed, i.e enhanced
effectiveness of soaps and detergents, eventual extension of the working
life of heating elements etc. There is no detectable alteration of the
drinking quality of the water, either hot or cold.
The CALCLEAR Water Conditioner unit reduced limescale deposit on the
test vessel by 84% over a 60 day period under laboratory conditions.
It is important to note that in most cases where the system has been
trialled, the particle count in the water has shown an increase in the
first few days. This is because the particles have been broken down to
under 4 micron size and the descaling process has begun to take limescale
deposits back into solution. Although there are more of these particles
they are incapable of reforming scale and will be flushed away and being
ionised they will help to further descale the entire water system.
