Portable Water Quality Analyzer ADPWA-501 measures residual chlorine over a broad range of 0.05 to 10 mg/L. It is reliable for sensitive applications and delivers high accuracy with minimal deviations. This unit uses spectrophotometric method to accurately detect chlorine at a wavelength of 520 nm. Equipped with an LED diode, it maintains consistent light intensity and reduces measurement errors. Our Water Quality Analyzer is highly versatile and effectively analyses environmental, wastewater and industrial samples efficiently.
