2020 Portable Turbidity Meter
The 2020 sets a new standard for
laboratory accuracy in an extremely
compact, portable instrument for
turbidity measurement.
A 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.

adapter (Order Code 1773) - the 2020 is an ideal choice for regulatory
monitoring, process water testing, and environmental water analysis in the
field or laboratory.
EPA Compliant - This nephelometric turbidity instrument meets or
exceeds EPA design specifications for NPDWR and NPDES turbidity
monitoring programs as specified by USEPA method 180.1. There is also
an EPA compliance reading mode which rounds the reading to meet EPA
reporting requirements.
Micro Processor Based - RANGE: 0 to 1100 NTUs. The microprocessor
enables auto-ranging over the full range of 0 to 1100 nephelometric
turbidity units (NTUs) and provides direct digital readout with a resolution
of 0.01 for the lowest range with an accuracy of ±2%.
Easy to Operate & Calibrate - The simple calibration procedure involves
activating the t or s keys until the reading matches the standard. The
microprocessor adjusts the factory programmed calibration curve
accordingly. Two primary turbidity standards are provided.
European CE Mark - The 2020 has been independently tested and has
earned the European CE Mark of compliance for electromagnetic
compatibility and safety.
RS-232 Interface - An RS-232 port is provided to interface with a
datalogger or computer. Optional cable available, Order Code 1772.
A Great Value - Attractively priced, the 2020 Portable Turbidity Meter
comes with AC adapter, four optically selected sample vials with screw
caps, standardization package consisting of 1.0 NTU (Order Code 1476)
and 10.0 NTU (Order Code 1477) AMCOTM standards, and an illustrated
instruction manual, all in a sturdy carrying case.
