  • Page 8: Overview

    <1. OVERVIEW> 1. OVERVIEW The applications of turbidimeters, which have been used for operation or control of fi ltration plants, are expanding into turbidity detection in chemical processes and in measurement of suspended solid particulates in various types of industrial wastewater. Model TB400G Scattered-light Turbidimeter is a process turbidimeter employing the principle of measuring surface-scattered light.

  • Page 9: System Confi Guration

    <1. OVERVIEW> 1.1 System Confi guration The TB400G scattered-light turbidimeter comprises a detector, converter and sampling system (which supplies process sample water, zero-calibration water (“zero water”), and cleaning water). This instrument is classifi ed into three types depending on the specifi cations for the sampling system.

  • Page 10: Tb400G-□-□-A3 (With Automatic Cleaning And Zero Calibration)

    <1. OVERVIEW> 1.1.4 TB400G-□-□-A3 (with automatic cleaning and zero calibration) This is a system which comprises the TB400G-□-□-A1 model with the automatic cleaning and automatic zero calibration functions added (see subsection 2.6.3). The sampling system of this system incorporates solenoid valves at the cleaning water tubing and zero calibration tubing and electric motor-operated valves under the header tank and at the measuring-water tubing.
