High-Precision ISO 7027 Compliant Measurement
Utilizes infrared LED (860±30nm) and 90° nephelometric method (ISO 7027 & DIN EN 27027 compliant) for accurate and reliable turbidity testing in both lab and field environments.
-
Wide Measuring Range & High Accuracy
Covers 0–1000 NTU with automatic range selection (0.01–19.99, 20.0–99.9, 100–1000 NTU).
Delivers ≤±2% of reading + stray light accuracy and ≤±1% or 0.02 NTU repeatability.
-
Dual Measurement Modes
Choose between Normal Mode for quick single readings or Average Mode, which automatically performs 10 consecutive measurements to display an average—ideal for unstable or settling samples.
-
Intuitive TFT Color Display
Large full-color screen provides graphic and text operation guides, with distinct display colors for measurement and calibration, ensuring clear and user-friendly operation.
-
EPA-Certified Calibration Solutions
Includes five AMCO polymer calibration standards (0.0, 20, 100, 400, 800 NTU)—non-toxic, NIST-traceable, stable, and EPA-approved for drinking water turbidity analysis.
-
Durable IP67 Waterproof Design
Built for field use with rugged housing and IP67 sealing, resistant to dust, moisture, and harsh conditions.
-
Complete Portable Test Kit
Comes in a sturdy carrying case with:
TN400 meter, 6 high-borosilicate glass vials (Φ25×60 mm), 4×AA batteries, calibration standards, silicone oil, microfiber cloth, and accessories.
-
Certified Quality & Warranty
CE, RoHS & FCC certified, backed by 2-year limited warranty from Apera Instruments, USA.
