PRELIMINARY EXAMINATION

LP 2000 is a bench microprocessor-based meter used to determine
the turbidity of water and wastewater. The meter covers the 0 to
1000 FTU* range with 0.01 resolution from 0.00 to 50.00 FTU* and
in single digits from 50 to 1000 FTU*. It also auto-ranges between
the two scales.

Note: LP 2000 has been designed according to the ISO 7027

International Standard. The turbidity measurement unit
is FTU (Formazine Turbidity Unit), which is identical to
NTU (Nephelometric Turbidity Unit).

The meter is housed in a rugged and lightweight case, with an easy-
to-read LCD.
The meter is simple to use: all operations can be carried out with only
four keys and troubleshooting functions can be performed with error
codes on the display. An exclusive positive-locking system guarantees
that the cuvette is firmly placed in the cell. The keypad is water-
resistant and can be wiped clean.
Calibration at 10 FTU* can be easily performed using the supplied
standard. In addition, LP 2000 is the first bench turbidity meter
that allows the storage and retrieval of the last calibration date.
10 FTU* was chosen as the calibration point because its value best
fits the water turbidity measurements in a wide range of applications,
from drinking water to wastewater treatment.
