1. OVERVIEW
The applications of turbidimeters, which have been used for operation or control of filtration
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. This instrument has the following features.
• High performance, high reliability
• Self-diagnostic functions (such as detection of a disconnected lamp, automatic converter
checking functions, and upper and lower limit alarms).
• Choice of functionality (such as automatic cleaning, range-free function, automatic zero
calibration, etc).
• Easy maintenance through small, light-weight, and accessible design.
• No window surfaces to become contaminated.
• Bubble rejection signal processing.

automatic zero calibration)
3rd Edition : May. 31, 2010-00

<1. OVERVIEW> 1-2
IM 12E04A02-02E
1.1 System Configuration
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 classified into three types depending on the specifications for the
sampling system. However, if specified in advance, the detector and converter may be delivered
separately.
Here, four types of the instrument, including the delivery of detector and converter separately,
will be described. Details on the detector and converter are described in Section 1.2, “Operating
Principle”.
1.1.1 TB400G-□-□-NN (without sampling system)
The detector and converter are available separately and can be assembled into any sampling
system.
The flowrate condition for sample is 1.5 to 2 l/min. If the flowrate exceeds this range, satisfy the
flowrate condition by providing a head tank (constant-level chamber) or the like.
For measurements of low turbidity (less than 200 mg/l), prepare a sampling system which can
supply the zero-calibration water (tap water filtered with a zero-turbidity filter).
1.1.2 TB400G-□-□-A1 (with sampling system, without
automatic cleaning or automatic zero calibration)
This is a system which combines the detector and converter with a sampling system to manually
supply process sample, zero-calibration water, and cleaning water (see subsection 2.6.1).
The measuring water flows into a header tank (constant-level chamber), serving also as a bubble
separation tank, after passing the ball valve located after the tap water inlet port.
Debubbled sample in this tank flow into the measuring cell in the detector at a constant flowrate,
and drains through the drain outlet after overflowing at the measuring cell.
The cleaning water passes the ball valve located after the tap water inlet port and flows into
the measuring cell in the detector from the cell side. The cleaning water then starts swirling
and removes dirt on the measuring cell wall. The dirt, together with the opening the ball valve
mounted under the header tank.
During zero check, the zero-calibration water is filtered by passing through a zeroturbidity filter
from the tap water inlet. This zero-calibration water flows into the measuring cell in the detector
via the head tank through a tube separate from that for the sample and drains through the drain
outlet.
1.1.3 TB400G-□-□-A2 (with automatic cleaning and without
automatic zero calibration)
This is a system which comprises the TB400G-□-□-A1 model with the automatic cleaning
function added (see subsection 2.6.2).
The sampling system of this system incorporates a solenoid valve at the cleaning water tube and
an electric motor-operated valve under the header tank. These provisions automatically clean the
measuring cell under the detector in a sequence preset in the converter.

<1. OVERVIEW> 1-3
IM 12E04A02-02E
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. These provisions automatically clean the measuring cell in the detector
and perform zero calibration in a sequence preset in the converter.
1.2 Operating Principle
The operating principle of the scattered-light turbidimeter employs a method of measuring the
amount of the light scattering that takes place close to the surface of the water sample. The
measuring system comprises a detector and a converter. This section describes the meter
configuration and operating principle.
The detector is comprises a measuring cell and a detecting section. Sample that flows into the
measuring cell from the bottom of the cell overflows at the top of the cell.
Meanwhile, a tungsten lamp closed inside the detector emits light onto the surface of the sample
through a system of lenses. This light is separated into scattered, reflected, and transmitted
light on the water’s surface. The transmitted light and reflected light are absorbed in a dark area
equivalent to a black body.
This scattered-light intensity (L) is proportional to the turbidity as shown here:
L = K • Q • S
Where K: a constant relative to turbidity,
S: turbidity,
Q: amount of light from the lamp.
The scattered light is detected by a turbidity element (a silicon photodiode). It is focused onto
the element with a lens inside the detecting section. This gives the scattered light signal to the
converter.
In addition, a reference element is incorporated in the detecting section to hold the amount a light
(Q) from the lamp constant, and it also provides a light-detection signal to the converter.
The measuring circuit of the converter is sealed in a housing of aluminum alloy together with the
operating panel and a terminal block for external wiring. This measuring circuit amplifies and
calculates the input from the turbidity element in the detector and outputs a signal (1 to 5 V DC or
4 to 20 mA DC) corresponding to the measuring range.
The converter also calculates the reference element input from the detector to control the lamp
voltage so that the amount of light from the lamp is constant.

2.2 Characteristics
Linearity (when using kaolin standard):
Upper range limit of 1000 mg/l (degrees) or less: ±2% of full scale
Upper range limit of 2000 mg/l (degrees) or less: ±5% of full scale
When the lower range value is a value other than 0 mg/l (degree),
the full scale should be interpreted as the upper range limit.
Linearity (when using polystyrene latex standard):
Upper range limit of 100 mg/l or less: ±2% of full scale
Upper range limit of 2000 mg/l or less: ±5% of full scale
Repeatability:
Standard solution: 2% of full scale
Calibration plate: 1% of full scale
Effect of Power Supply Voltage: Within ±1% of full scale/±10% of rated voltage
Effect of Ambient Temperature: ±1% of full scale/10 °C (calibration plate)
Response Time: Within 2 minutes (90% response, with sampling system, at a flow rate of 3
l/min)
Warm-up Time: Approx. 30 minutes

Calibration using polystyrene latex *7
*1 Provide a defoaming tank (head tank) so that the flow rate of the water sample reaches the specified flow (1.5 to 2 l/min).
*2 Optional specifications for selecting “without sampling system (code: -NN)”
*3 Optional specifications for selecting “with sampling system (code: -A1, -A2, or -A3)”
*4 For applications where the measuring range is low (200 mg/l or less) and air bubbles are likely to occur, add the “L” option (spike
detection function). This option is not available for higher measuring range.
*5 A pH meter or non-reagent type free available chlorine analyzer should be purchased separately when the relevant option code
is specified. You can select only one optional specification in the /PHN or / PHU option or the /FC option on the one turbidimeter.
*6 Option code /ARS cannot be selected when /PHN or /PHU or /FC option is specified.
*7 Polystyrene latex of 2 degrees is used as standard. Polystyrene latex with a size of up to 100 degrees may be handled as
Tokuchu. Kaolin is used as turbidity standard for calibration unless the /PSL option is specified.
