PRELIMINARY EXAMINATION

GENERAL DESCRIPTION

LP2000-11

 is housed in a rugged and lightweight case, with an

easy-to-read LCD.
The meter is simply to use. All operations can be carried out with only
five keys and troubleshooting functions can be performed with
displayed error code guides. A positive-locking system guarantees that
the cuvet is firmly placed in the cell. The keypad is water-resistant
and can be wiped with a moist cloth for quick cleanups.

Two or three points calibration (0, 10, 500 FTU*) can be easily
performed using available standards.

Remove the instrument from the packing material and examine it to make
sure that no damage has occurred during shipping. If there is any
damage, notify your Dealer.

LP2000-11

 

is  supplied with:

Glass cuvet with cap

• AMCO-EPA-1 turbidity calibration solutions (

HI 93703-0

 @0 FTU

and 

HI 93703-10

 @10 FTU), 30 mL each

12 Vdc power adapter and instruction manual

Note:

 Save all packing material until you are sure that the instrument

functions correctly. Any defective item must be returned in its
original packaging with the supplied accessories.

LP2000-11

 turbidity meter is a bench top, microprocessor-based instrument

used to determine the turbidity of water and wastewater. The meter covers
a 0-1000 FTU range in two scales: 0.00 to 50.00 FTU and 50 to 1000
FTU. The autoranging feature sets the appropriate range for the
measurement.
The serial interface is supported connecting any available serial port on
your PC and a 5-pin socket on the meter.

Note:

LP2000-11

 has been designed according to the ISO 7027

International Standard, consequently the turbidity
measurement units are expressed in FTU (Formazine Turbidity
Unit). FTU is identical to the other internationally recognized
unit NTU (Nephelometric Turbidity Unit).
