Portable Analyzer
Focused Photonics Inc. (FPI) enables field-ready water assessment with its Portable Analyzer series, providing handheld, multi-parameter detection of turbidity, pH, COD, ammonia, and ions in rivers, lakes, and effluents. The SIA and portable series utilize light scattering, UV absorbance, and ISE technologies for compliance with ISO 7027, GB 3838-2002, and EPA Method 180.1.
Field Audit: Principles of Portable Detection
Portable analyzers quantify water parameters through miniaturized optics and electrochemistry for instant, on-site validation. FPI’s tools employ Nephelometric light scattering at 90° for turbidity (0-1000 NTU, ±1 NTU), UV absorbance at 254 nm for COD (0-500 mg/L, ±0.1 mg/L), and ISE for ions/pH (0-14, ±0.01), per ISO 7027.
