Comparison with other KH measurements
Our investigations have shown that different measuring methods (droplet tests or measuring
instruments from various manufacturers) hardly yield any consistent results.
In most cases, several successive measurements with the same equipment show more or
less deviant results. It is therefore difficult to judge which result is the "right one".
Here, the KH Director shows another strength: The results are calculated exactly according to
scientific principles and are typically reproducible down to 0.1 ° dKH.

Conclusion
Every measurement is subject to tolerances, yet the KH Director delivers a high degree of
precision when used carefully.
For effective measurement and control (if used) we recommend the following:
1.
Make sure the measurement achieves reasonable accuracy with reasonable effort.
2.
Adjust the control in a way, that the desired optimum KH range is maintained.
3.
Do not choose this area too narrow (recommendation: range approx. 1.5° dKH, for
example 7° dKH to 8.5° dKH).

Maintenance
The
KH Director®
is largely maintenance-free. It is recommended to clean the device from
dust and other contaminants.
Tubes, pumps and motors are wearing parts, the service life depends on the frequency
of use, the flow rates and the ambient conditions
.
In the event of malfunction (for example, inadequate fluid delivery, loss of suction, leakage,
increased operating noise) or mechanical failure, these must be replaced.
Due to the maintenance-friendly design, all wear parts can be easily replaced by yourself, all
wearing parts are available as accessories.

Warranty/Liability
You have a 2-year warranty beginning from invoice date. This applies to material and
manufacturing defects.
