PORTABLE TURBIDITY METER:
The newly redesigned 2020e combines an advanced microprocessor with a patent-pending optical chamber resulting
in higher accuracy and a wider range.
• Patent pending optical design features focusing optics for low level precision and accuracy. • MSP430 Microcontroller used is the most advanced controller on the market for hand held applications. • Advanced calibration algorithms. • Tube positioning ring limits vial variability. • Easy menu driven operation and large LCD display. • 4000 point data log, stored results can be viewed directly on instrument or downloaded to a computer via RS232 cable. • LaMotte 2020e Turbidity Meter Owners Manual • Turbidity Meter Troubleshooting Guide • AMCO Turbidity Standards, ISO 7027 Certificate of Compliance

TURBIDITY TUBE:
Accurately measures water clarity. Features a clear polycarbonate tube with numeric centimeter scale on the side and a 4.5 cm
standard secchi disc design in the bottom of tube. Secchi disc is screwed to a rubber stopper, which can be removed for easy cleaning.
Drain hose with finger crimp allows sample to be drawn off until secchi pattern is visible. 60 cm in length.

SECCHI DISKS:
Used to determine turbidity or degree of visibility in natural waters. The 20 cm (8") diameter discs
come with 3/4 lb lead weights. Calibrated line is 20 meters in length.

BRAIDED LINE & WEIGHT:
This 20 meter, braided, stretch-resistant line has a brass spring clip for easy attachment to samplers,
secchi disks, plankton nets or sounding leads. The line wraps conveniently around an ethafoam block,
which prevents accidental loss.

TURBIDITY STANDARDS:
Hach StablCal Stabilized Formazin Primary Standards:
These are true formazin dilutions developed for use in any turbidimeter. Shelf life is
guaranteed for two years from date of manufacture. Requires no special preparation,
no dilution and no special glassware or handling. Available in 100 ml or 500 ml bottles.
Sets are also available which include a range of NTU values. NTU values available range
from <0.1 to 7500 NTU. Please inquire for pricing and availability on values not listed.

LaMOTTE TURBIDITY TEST KIT:
This visual comparison test kit is designed for use in shallow waters where secchi
disc depth reading is not feasible. Readings are made by using a standard turbidity
reagent to match the turbidity of a water sample. Measurements are expressed in Jackson
Turbidity Units (JTU). Reads from 0-200 JTU in 5 JTU steps.

IMHOFF CONE:
Fully graduated cone made of styrene-acrylonitrile. It features a low density
plug which makes it easy to withdraw sediment. Markings are incremented as
follows: 0 to 1 ml by 0.1 ml, 1 to 10 ml by 0.5 ml, 10 to 40 ml by 1.0 ml, 40 to 100 ml
by 2 ml, and markings at 250, 500, and 1000 ml.
