1. OVERVIEW
Surface Scattering Light Turbidity Detector, composed of Turbidity Detector TB830D and Liquid
Analyzer FLXA402T, is a next-generation analyzer, developed based on years of experience,
combining the reliable measurement principle with our latest digital sensor technology realizing
high e󰀩ciency in facility operations. The product has successfully extended its life by employing
LED as the light source.
1.1 Measurement system and structure
TB830D is used with FLXA402T Liquid Analyzer for Turbidity and Chlorine. TB830D also can be
used with a sampling system to control the pressure or ow rate of samples.
lTB830D Surface Scattering Light Turbidity Detector
TB830D measures turbidity. The Detection unit consists of the following three parts.
● Flow cell: A sample ows through it. A light beam is emitted from the light source
onto the sample solution.
● Detection unit: An optical system incorporating a Light source, Receiver, and lenses.
Desiccant equipped helps the dryness inside.
● Smart unit: Memory of parameters, the control unit
l FLXA402T Liquid Analyzer for Turbidity and Chlorine (converter)
Displays/Outputs measurement or status of connected detectors or controls detectors.
Refer to IM 12A01G01-03EN for the setup of the display, input/output, or communication.
l Sampling System
The Head tank enables the pressure of a sample and the ow rate to stabilize. The Head tank
also reduces the e󰀨ect of air bubbles.
For Automatic cleaning/Automatic zero calibration, a Relay box and/or solenoid valve is mounted.

*1: “-AJ” is no standard.
*2: Install the head tank so that the ow rate of the detector is the specied ow rate (1.5 to 2 L/min). Customers have to
arrange a head tank.
*3: 1 μm zero turbidity lter is supplied with the product.
*4: Cleaning, zero calibration, span calibration are enabled manually.
*5: This is selectable only when Sampling system “-NN” or “-A5” is specied.
*6: This is not selectable when Sampling system “-A1”, “-A2”, “-A3” is specied. 1 m cable is supplied with the product. Select
