Critical Industrial Applications & Engineering Strengths

Why Total Suspended Solids (TSS) Monitoring Matters

TSS measures particulate matter suspended in water, affecting light penetration, aquatic habitats, and filter efficiency. Key application sectors include:

Municipal Wastewater Treatment: Controlling return activated sludge (RAS) and secondary clarifier effluent
Industrial Process Effluent: Paper, mining, food processing, and textile wastewater discharge compliance
Surface & Coastal Water Survey: Monitoring silt, sediment runoff, and dredging operations
Drinking Water Plant Intake: Pre-screening raw surface water sediment spikes before coagulation

Qiwei Manufacturing & OEM Advantages

Empowering global water equipment distributors, system integrators, and instrument brands:

Infrared Optical Design: 860 nm infrared light source eliminates color interference in complex industrial samples
Fast Non-Destructive Testing: Delivers instant readings, drastically speeding up field decision-making compared to gravimetric methods
OEM & ODM Customization: Custom probe lengths, housing colors, logo branding, and localized UI software
Internal Links: Combine with our Iron Testers, Spectrophotometers, Nickel Testers, and Sulfuric Acid Meters for complete water analysis.

Frequently Asked Questions (TSS Meter Sourcing Guide)

Q1: What is the difference between Turbidity (NTU) and Total Suspended Solids (TSS mg/L)?

Turbidity measures light clarity/scattering caused by particles (in NTU/FTU), whereas TSS measures the actual weight concentration of suspended solids (in mg/L or ppm). Qiwei TSS meters support custom correlation curves to directly convert optical readings into TSS mass values.

Q2: How does sample color affect TSS optical readings?

Qiwei TSS analyzers utilize an 860 nm near-infrared light source. Because water sample colors absorb visible light but not near-infrared wavelengths, sample color interference is virtually eliminated.

Q3: Do you support OEM custom branding and wholesale distributor pricing?

Yes, as a factory-direct manufacturer, we provide complete OEM/ODM custom branding, customized UI interfaces, and tiered volume discounts for global laboratory suppliers and engineering contractors.
