Turbidity Checker (High Range) TC Series

 Turbidity Checker (High Range) TC Series
  • TC-3000[Checker][Parts No. 05049]

Make turbidity check easier and more compact. And realize significant cost savings.


● Built-in wiping cleaning system certainly keeps lenses clean.
   Check and clean the window surface once every month.

● "Easy to clean" scratch-proof sapphire glass applies to the optical windows.
   The optical windows are made of hard-to-scratch sapphire glass. It enables you to scrub the windows surface without problems.

● Compact size can fit into any installation site.
   The compact design makes it possible to install any places.

 Compact size

● Continuous measurements can be achieved by installing only one checker.
   Built-in analog output function covering 4 to 20 mA is incorporated, which makes it possible to transmit data to various equipment according to your applications.


The TC-3000 can be installed at various sites throughout the factory.

1.Monitoring acquisition of water for factory use

By monitoring the turbidity of the water when it arrives, we can prevent trouble in the event that there is a sudden shift in turbidity down the line.

Water intake
2.Turbidity monitoring at each stage in the manufacturing process

This facilitates easy pinpointing of where the problem started in the event that an abnormality occurs in wastewater treatment.
By monitoring the primary treatment facility, we can achieve more stable operation of the final treatment facility.

3. Turbidity monitoring at the cooling tower

It is possible to control the operation of the water filtration equipment and adjust the blow water volume according to the turbidity monitoring concentration after applying a cleaning agent.

4.Rainwater pit

This allows valve control to deliver only high-concentration initial rainwater to the treatment facility and run water into the river at the point treatment is no longer needed.

5.Monitoring drainage outside the manufacturing process

We can achieve total management of a factory’s wastewater by monitoring not only the water used in the manufacturing process but also that used in the purification tank, etc.

6.Coagulant control

By firmly establishing the correct concentration of wastewater, we can insert the appropriate amount of cleaning agent, allowing us to achieve a stable water quality.

7.Sludge interface check

By attaching a sensor to the settling tank, the sludge interface can be monitored.
Setting sensors up in two or three different stages creates a more accurate picture of the interface.

Setting tank
8.Monitoring of sludge overflow

We can perform functions like monitoring overflow of sludge, halting the drainage of water, and returning it to the raw treatment water.

9.Monitoring of water outflow

This allows for final monitoring of the treated water as flows out into the river.

10.Remote monitoring of turbidity in rivers

By combining our sensors with NiGK Corporation’s solar-panel-mounted “aqua e monitor,” we can remotely observe even places such as rivers, where an electric power supply can’t be secured.
