Features

|
|
|
|
|
Total hardness, that is the presence of magnesium and calcium,
is due mainly to the runoff
|
|
|
water dissolving these salts as it
flows or filters through different strata. Hardness can also cause
|
|
|
scaling of pipes in cooling and heating
systems.
|
|
|
|
|
|
The
HI 93735 measures the total hardness in drinking, surface and wastewater.
|
|
|
|
|
|
This meter uses an exclusive positive-locking system to ensure
that the cuvette is in the same position
|
|
|
every time it is placed into the
measurement cell. It is designed to fit cuvettes with a larger neck
|
|
|
making it easier to add both sample and
reagents. The cuvettes are made from special optical
|
|
|
glass to obtain best results.
