TN500 Portable White Light Turbidity Meter with GLP Data Logger, EPA 180.1 Compliant

Features:

1. EPA 180.1 Compliant for Reliable Water Analysis: Uses a tungsten filament lamp and 90° scattering method, fully compliant with U.S. EPA 180.1 for accurate turbidity measurement in tap water, drinking water, wastewater, and environmental applications.

2. Optimized for Low-Range Accuracy (<10 NTU): The premium-quality tungsten lamp ensures superior sensitivity in low-turbidity samples; the lamp is user-replaceable for long-term reliability and cost efficiency.

3. Multi-Reading Mode: Automatically captures multiple consecutive measurements, then calculates and displays average, minimum, and maximum values with a brief report — providing the true turbidity of your sample, not just one random reading.

4. Safe, Stable EPA-Approved Calibration Standards: Includes AMCO high-molecular polymer standards (0, 20, 100, 400, 800 NTU) — EPA-approved, NIST-traceable, non-toxic, and guaranteed stable for one year without settling or precipitation.

5. Zero-Point Calibration with Error Reminder: Built-in zero turbidity calibration and error alert functions ensure consistent accuracy, especially critical for low-turbidity measurements.

6. Intuitive Multi-Language Color Display: Large TFT color screen with on-screen operation guides supports English, Spanish, and Chinese, making setup and testing effortless.

7. Extended Battery Life with USB Power: Rechargeable 3.7V lithium battery provides up to 20 hours of continuous testing, over 5× longer lifespan than standard meters. Recharge easily via USB charger or PC.

8. GLP Data Storage & Connectivity: Stores 200 sets of readings with real-time clock, calibration history, and USB data export to PC via the included PC-Link software for GLP data management.

9. Built for Field and Lab Environments: IP67 water-resistant housing, rugged construction, and smart auto power-off design make the TN500 perfect for demanding fieldwork and laboratory use.
