The 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.

TB500-CAL Online Turbidity Analyzer Primary Calibration Kit for TB502 & 504 (PN# DN0300)
TB500-IFR Online Turbidity Analyzer Inline Flow Regulator (PN# DN0390)
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.
TB500-ALR Online Turbidity Analyzer Flow Alarm (PN# DN0380)
This option indicates a “Low Flow” condition by switching both relays to the fail state and setting the 4-20 mA signal to 2 mA. There is also a screen indication of the low flow condition and a modbus register is set.
