The TRB-2020 combines laboratory
accuracy and reliability in an extremely
compact, portable instrument for
turbidity measurement over the wide
range of 0 to 4000 NTUs.
A multi-detector optical configuration
assures long term stability and
minimizes stray light and color
interference. All readings are
determined by the process of
signal-averaging over a 5-second
period minimizing fluctuations in
readings attributable to large particles
and enabling rapid, highly repeatable
Supplied with a 9 volt alkaline battery, the
TRB-2020 is an ideal choice for
regulatory monitoring, process water
testing, and environmental water
analysis in the field or laboratory.
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 readings to meet EPA reporting
0 to 4000 NTUs. The microprocessor
enables auto-ranging over the full range
of 0 to 4000 nephelometric turbidity
units (NTUs) and provides direct digital
readout with a resolution of 0.01 for the
lowest range and an accuracy of ±2%.
The simple calibration procedure
involves activating the UP or DOWN
arrow keys until the reading matches the
standard. The microprocessor adjusts
the factory-programmed calibration
curve accordingly. Two primary turbidity
standards are provided.
An RS-232 port is provided to interface
with a datalogger or computer.
Attractively priced, the TRB-2020
portable turbidity meter comes
with 0, 1, and 10 NTU standards,
sample bottles, 4 sample vials,
extra battery, and illustrated instruction
manual, all in a sturdy carrying case.
