How does the Multipath 90° BLAC® technology improve turbidity measurement accuracy?
The Multipath 90° BLAC® technology utilizes a sophisticated arrangement of dual detectors to eliminate stray light and provide ratio readings. This ensures high accuracy across the entire measuring range (0.01 to 4,000 NTU), even in samples with varying particle sizes and shapes. The technology maintains a consistent 90° angle of detection, delivering reliable results under all conditions.
Can the TB 350 be calibrated with Formazin standards, and how frequently should calibration be performed?
Yes, the TB 350 can be calibrated using Formazin standards, complying with ISO 7027 requirements. Calibration frequency depends on usage and the criticality of the measurements. For routine monitoring, a monthly calibration is recommended. However, for high-precision applications, weekly calibration or verification with standards is advisable.
What measures are in place to prevent interference from ambient light during field measurements?
How does the TB 350 handle samples with high turbidity levels, and is there a risk of sensor saturation?
The TB 350’s wide measuring range up to 4,000 NTU ensures that it can accurately measure high turbidity levels without sensor saturation. The device employs a ratio mode to adjust for varying turbidity levels, preventing saturation and maintaining accuracy. However, for extremely high turbidity samples, dilution may be necessary to ensure optimal sensor performance.
What are the data management capabilities of the TB 350, and how can data be integrated into existing monitoring systems?
The TB 350 features a robust data logging system that can store up to 250 measurements, along with calibration and verification data. Data can be transferred to a computer via USB in .csv format, facilitating integration into existing water quality monitoring systems. The device’s data management capabilities enable seamless tracking, analysis, and reporting of turbidity measurements.
Is the TB 350 suitable for continuous monitoring applications, and what are the best practices for maintaining sensor accuracy over extended periods?
