Portable Turbidity Meter – ISO 7027 Compliant Field & Process Analyzer
The Instrava Portable Turbidity Meter is a high-performance field and process analyzer engineered for precise turbidity measurement across drinking water, beverage production, aquaculture, and industrial applications.
Designed in accordance with ISO 7027, the instrument utilizes an 850 nm infrared LED light source and silicon photodiode detector to ensure stable, low-interference measurement performance. With 2 to 5 point calibration, selectable turbidity units (NTU, FNU, EBC, ASBC), and expanded memory storage, the meter provides reliable and traceable results for both compliance verification and process control.
Built for professional users, it supports both single measurement mode (auto-lock stable reading) and continuous measurement mode, enabling fast inspections and comparative sample analysis.
