Online Turbidity Analyzers Product Description
The Global Water TB500 series online turbidimeters are
specifically designed for the continuous measurement of
turbidity in filtered water, raw water, final wastewater
effluent and many industrial applications. Two models
of the TB500 online turbidity analyzers are available:
The TB502 is a great value, providing reliable and
economical online turbidity monitoring with a range of 0
to 1,000 NTUs. The TB504 online turbidimeters feature
an EPA accepted ultrasonic cleaning system that keeps
the optical chamber clean in raw and finished water
applications. The TB504 online turbidimeters also
feature a versatile range of 0 to 1,000 NTUs with an
accuracy that is the same or better than many smaller
range instruments.
Online Turbidity Analyzer Light Source
We offer the TB500 series online tubidimeters in two
different versions to meet the needs of different
measuring standards. White light is recommended for use
in online turbidimeters reporting results under US EPA
(US standard) jurisdiction. The online turbidity
analyzer's WL (White Light) versions use a new krypton
filled white light technology with lamp life expectancy
up to 7 years. The online turbidity analyzer's IR
versions feature a long life infrared light source,
which is recommended for use in online turbidimeters
reporting results under ISO 7027 (European standard)
jurisdiction. Infrared light is also recommended for
waste water final effluent and industrial applications
where color is present in the sample stream.
Online Turbidity Analyzer Calibration
Online turbidimeter calibration with primary standards
is completed using sealed cuvettes, similar to
laboratory procedures. This dry method of online
turbidimeter calibration is fast, clean and reusable.
On-screen menu items guide you through the online
turbidity analyzer's calibration procedure quickly and
easily. The online turbidimeters have reusable primary
standards which are contained in sealed glass cuvettes.
Simply place the cuvette into the online turbidity
analyzer's measuring chamber and verify the reading—just
like a laboratory turbidity meter.
Online Turbidity Analyzer Advanced Design
The TB500 online turbidimeter’s new optical design
allows consistent readings with laboratory and portable
turbidimeters. The online turbidity analyzer's optical
chamber has been designed to eliminate air in the sample
while simultaneously creating a vortex cleaning action
throughout the chamber. The online turbidity analyzer's
low-volume sample chamber (30-mL) reduces calibration
costs and provides quick response times. The online
turbidity analyzerhas a compact, one-piece, NEMA 4X
enclosure is suitable for outdoor installation (within
temperature limitations) and allows for simple mounting
and minimal use of space. The TB500 online
turbidimeter’s intuitive user interface features
security code settings to prevent unauthorized tampering
with the programming. A built-in diagnostic menu on the
online turbidimeter assists in troubleshooting.
Online Turbidity Analyzer Outputs
The TB500 online turbidimeter includes an isolated 4-20
mA current output that may be used for chart or data
recording, remote monitoring, PLCs or SCADA systems.
Two user settable alarm relays on the online turbidity
analyzer may be connected to an autodialer or local
alarm to notify you before dangerously high turbidity
levels occur. Also included is an RS485 digital output
that may be interfaced with a Modbus system to link
multiple units or to integrate the TB500 online
turbidimeter into your existing network.
Each TB500 online turbidimeter is shipped fully
calibrated and includes desiccant, inline pressure
regulator, universal 100-250 volt power supply and an
operator's manual. The TB502 online turbidity analyzer
models also include a spare measuring cuvette with light
shield.

TB500-IFR Online Turbidity Analyzer Inline Flow
Regulator
The inline flow regulator limits the flow, in
high-pressure systems, to safe flow limits of less
than 1 liter/minute. Recommended for pressurized
lines. |
