❓ Frequently Asked Questions (FAQ)
Q1: What does the Extech TB400 measure?
A. The Extech TB400 is a turbidity meter used for turbidity measurement, helping users determine how clear or cloudy a liquid is.
Q2: What is turbidity?
A. Turbidity refers to the level of particles suspended in a liquid. Higher turbidity means the liquid appears more cloudy.
Q3: Does the TB400 require calibration?
A. Yes, it uses calibration standards to ensure accurate turbidity measurement.
Q4: What does NTU mean?
NTU (Nephelometric Turbidity Units) is a standard unit used to measure turbidity, meaning how cloudy or murky a liquid is - usually water.NTU is based on how much light is scattered by particles in the water.
The more particles present (like dirt, algae, or sediment), the higher the NTU value.
Simple way to think about it
- 0.0 - 0.5 NTU → clear water
- 1–5 NTU → slightly cloudy
- 100+ NTU → very murky, lots of suspended material
Final Thoughts
