The HANNA® HI83414 Multiparameter Benchtop Meter is a high-precision laboratory instrument designed for the simultaneous measurement of turbidity, free chlorine, and total chlorine in drinking water, wastewater, and environmental samples. Utilizing an advanced optical system with tungsten lamp technology, ratio nephelometric detection, and narrow-band interference filters, the HI83414 delivers highly accurate and reproducible measurements while minimizing stray light and color interferences.
This instrument integrates turbidity and chlorine analysis in a single benchtop platform, making it ideal for water treatment plants, environmental laboratories, regulatory agencies, and research facilities requiring reliable water quality monitoring.
Measurement Parameters
| Parameter | Range | Resolution | Accuracy |
|---|---|---|---|
| Turbidity (Ratio Mode) | 0.00 to 4000 NTU | 0.01 to 1 NTU | ±2% of reading ±0.02 NTU |
| Turbidity (Non-Ratio Mode) | 0.00 to 40.0 NTU | 0.01 to 0.1 NTU | High linearity low-range |
| Free Chlorine | 0.00 to 5.00 mg/L | 0.01 mg/L | ±0.02 mg/L @ 1.00 mg/L |
| Total Chlorine | 0.00 to 5.00 mg/L | 0.01 mg/L | ±0.02 mg/L @ 1.00 mg/L |
Additional turbidity units supported:
- NTU (Nephelometric Turbidity Units)
- EBC (European Brewing Convention Units)
- Nephelos Units
Optical System and Measurement Technology
The HI83414 features a sophisticated optical design incorporating:
- Tungsten filament lamp (stable light source)
- 90° scattered light detector for nephelometric turbidity measurement
- 180° transmitted light detector for ratio turbidity correction
- 525 nm narrow-band interference filter for chlorine measurement
- Silicon photodetector for high sensitivity detection
- Special optical glass cuvettes (25 mm path length) for maximum repeatability
Ratio measurement technology compensates for color interference and lamp intensity variations, ensuring accurate turbidity readings across a wide measurement range.
