Extech TB400 Portable Turbidity Meter

What is the Extech TB400 Portable Turbidity Meter?

The Extech TB400 Portable Turbidity Meter is designed for UK technicians and facilities teams who need fast, reliable measurement of water clarity and turbidity directly on site. It measures turbidity up to 1000 NTU with 0.01 NTU resolution, making it suitable for municipal water checks, building water systems and environmental investigations where water quality needs to be assessed quickly.

Its portable, battery-powered design allows measurements to be taken at the point of use, removing the need to transport samples back to a laboratory. Microprocessor-based circuitry ensures consistent, repeatable results, while the meter meets ISO 7027 requirements for turbidity measurement.

 

How does the TB400 support field testing and inspections?

The TB400 requires only a 10 mL sample, allowing quick testing with minimal preparation. Two-point calibration, fast response time and a clear backlit display make it easy to use during routine inspections or investigations. Supplied calibration standards and accessories mean technicians can begin testing straight out of the case.
