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.

Features:

Field & Lab Use - Supplied with a 9 volt alkaline battery and an AC power 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.
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.
RS-232 Interface - An RS-232 port is provided to interface with a datalogger or computer. Optional cable available, Order Code 1772.
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.
