They consist of light source including laser, for measuring turbidity levels accurately. Their photodetector captures scattered light, converting it into measurable electrical signals for analysis. They feature sample chamber where water samples are placed for turbidity testing. Our Turbidity Meter evaluates water clarity in wastewater treatment, aquaculture, storm water management, recreational water testing.








Labtron Portable Turbidity Meter is designed for accurate turbidity analysis across a broad range, making it suitable for drinking water facilities, and food processing applications. It effectively analyzes both low and high turbidity samples with a measuring range of 0 to 100 NTU and 100 to 400 NTU. Its application is valuable for ensuring regulatory compliance and maintaining product quality. This versatility makes it an essential tool for both research and operational settings.
Our Portable Turbidity Meter ensures precise accuracy across its full measuring range with a 5-point calibration system. It employs ISO 7027-standard formazine solution, minimizing measurement deviations in various environmental conditions. The infrared-emitting diode ensures stable readings unaffected by sample color. This device combined with high throughput stability remains reliable in both lab and field use.
The Portable Turbidity Meter's compact, lightweight design of 1.5 kg and a protective carrying case make it highly portable for fieldwork. It operates on standard AA batteries or AC power, providing flexibility in power-limited environments. The LCD display with a touch keypad and intuitive menu options simplifies navigation and data entry. Our meter's quick operation allows technicians to perform fast and efficient testing.
Labtron's Portable Turbidity Meter offers built-in memory that allows users to store up to 20 sets of readings, supporting comparisons and data logging for trend analysis. It also features non-linear data processing and transfer, which refines accuracy in irregular or variable turbidity samples. This capability supports data integrity in GLP-compliant environments. Users can rely on it for routine or audit-based reporting.
The Portable Turbidity Meter uses a 90° scattered light method with a silicon photodiode and an 850 nm infrared light source, offering dependable turbidity measurements. This method is highly sensitive to particulate matter and less affected by sample coloration. It ensures consistent results even with small sample volume of 5 to 10 ml. Our meter's design promotes repeatability and reduces user error during readings.
