Buying Guide: Key Considerations For Selecting A TSS Analyser
What range do you need? Most models cover 0–2000 NTU, which suits routine lab work and many industrial applications. If you anticipate very high turbidity readings, confirm the upper limit and calibration options.
Which units are essential? Look for devices that support NTU, FNU, EBC, and ASBC. Multiple units simplify cross-lab comparisons and meet diverse reporting standards.
How important is calibration? Formazin-based calibration is common. Ensure the instrument offers 2–7 point calibrations and provides calibration standards and straightforward reset procedures.
Connectivity and data handling matter. USB interfaces enable easy data export to lab software, spreadsheets, or LIMS. Check compatibility with your existing systems.
Accuracy and precision. While exact figures depend on method and standards, prioritize devices that specify calibration procedures, resolution (0.01 or 0.01 NTU), and repeatability information in the product details.
Dedicated TSS mode. Some models include a Total Suspended Solids mode for direct calculation from turbidity data. This can simplify workflows in QC environments.
Frequently Asked Questions
- What is a total suspended solids analyser? A TSS analyser measures the amount of suspended particles in a liquid by analyzing turbidity and applying a calibration that converts turbidity readings to solids concentration.
- Why are multiple turbidity units important? Different laboratories and industries use NTU, FNU, EBC, or ASBC. Having multiple units allows consistent reporting and cross-site comparisons.
- Do these devices require calibration standards? Yes. Most include Formazin standards for 2–7 point calibrations to ensure accuracy across the measurement range.
- Is USB connectivity necessary? USB enables easy data transfer to computers or lab software, making long-term data management simpler.
- What should I consider when choosing a TSS analyser? Consider range, units, calibration options, data connectivity, size, and whether you need a kit or standalone unit for your workflow.
- What are common limitations? Calibration material handling, unit-specific accuracy, and device footprint can affect usability in smaller labs or field settings.
