Product description

Portable turbidity meter using tungsten lamp and 90° scattering, EPA 180.1 compliant for water quality analysis.

The Apera TN500 Portable White Light Turbidity Meter is designed for precise turbidity measurement in drinking, ground, surface, and saline waters, as well as domestic and industrial wastewater. Utilizing a tungsten filament lamp with a 90° light scattering detection method, the device complies with the U.S. EPA 180.1 standard, ensuring accurate and reliable data critical for environmental monitoring and molecular diagnostics workflows focused on water quality.

Key technical features include:

  • EPA 180.1 method compliance for regulatory-standard turbidity measurement
  • White light tungsten filament lamp providing stable illumination for precise scattering analysis
  • Intuitive operation system ensuring efficient field use by water quality professionals and bioprocessing specialists
  • Long-term instrument reliability ideal for continuous environmental and clinical diagnostics monitoring
  • Simple calibration and GLP-compliant data management facilitating traceable and reproducible measurements
  • Integrated data logger supporting detailed analysis in biomanufacturing and synthetic biology applications involving aqueous solutions

The TN500 is widely adopted in environmental biotechnology, molecular diagnostics, and biomedical engineering research domains for assessing water clarity and turbidity — essential parameters in bioprocessing and gene editing workflows requiring strict water quality control. This portable turbidity meter offers a robust solution for both onsite and laboratory water quality analysis, supporting critical regulatory compliance and advanced synthetic biology applications.

Why Questpair exists

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.

We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.

We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
