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.
The multi-detector optical configuration assures long term stability and minimizes stray light and color interferences. All readings are determined by the process of signal averaging over a 5 second period. This minimizes fluctuations in readings attributed to large particles and results in rapid, highly repeatable measurements. Ideally suited for both low-level drinking water applications as well as monitoring high turbidity in the field.

2020e version meets USEPA design criteria as specified by USEPA method 180.1.

Kits are supplied with 0, 1, and 10 NTU standard, sample bottle, four sample tubes, hard shelled carrying case, and an extra battery. AC power adapter is optional.

turbidity tube
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.

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.

turbidity kit
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.

#R-7519: Turbidity Refill Reagent, 50 ml $11.50
imhoff cone
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.
