Portable Turbidity Meter

2020_portable_turbidity_meter.jpg (10064 octets) 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 minimizing fluctuations in readings attributed to large particles and enabling rapid, highly repeatable measurements.

Features

Field & lab
Supplied with a 9 volt alkaline battery and an AC power adapter - 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.
Microprocessor 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 arrow 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.
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 and 10.0 NTU AMCO⑩ standards, illustrated instruction manual, all in a sturdy carrying case.
