color touch screen interface with bilingual display
These features allow laboratories and plant operators to maintain traceable turbidity records and ensure water clarity compliance with regulatory standards.
How accurate is a benchtop turbidity meter compared to portable turbidity meters?
Benchtop turbidity meters generally provide higher measurement stability and precision than portable devices because they use a more stable optical system and controlled measurement environment.
Instrava’s benchtop turbidity meter provides:
≤ ±2% full-scale accuracy
≤ ±2% repeatability
≤0.002A/20min optical stability
This level of performance makes it suitable for laboratory verification, process monitoring, and regulatory reporting.
What turbidity range is suitable for drinking water testing?
Most drinking water quality regulations require turbidity to remain below 1 NTU, and often below 0.5 NTU in treated water distribution systems.
A 0–400 NTU measuring range ensures the instrument can handle:
raw water monitoring
filtration performance verification
treated water turbidity validation
without needing multiple instruments for different ranges.
How does the optical interference system improve turbidity measurement reliability?
The cold light narrow-band interference optical system provides several engineering advantages:
reduced stray light interference
improved long-term optical stability
better signal-to-noise ratio
This ensures consistent turbidity readings even during continuous laboratory testing or frequent calibration cycles.
