potable turbidity meter, EPA, 230V

Portable multiparameter turbidity meter, EPA, 230 V is a USEPA-compliant mobile instrument for high-precision turbidity and free/total chlorine measurement, developed especially for low-range applications such as drinking water. The optical system combines a tungsten lamp, three detectors (scattered light, transmitted light and colorimetric) and a narrow-band interference filter at 525 nm to ensure stability, minimise stray light and colour interference, compensate lamp fluctuations and reduce calibration needs. Turbidity ranges are 0,00 to 9,99; 10,0 to 99,9 and 100 to 1000 NTU with resolutions of 0,01; 0,1 and 1 NTU; free and total chlorine each cover 0,00 to 5,00 mg/l (resolution 0,01 mg/l to 3,50 mg/l; 0,10 above). Turbidity accuracy is ±2% of reading plus 0,02 NTU; chlorine accuracy is ±0,02 mg/l at 1,00 mg/l. Nephelometric ratio measurement follows USEPA Method 180.1 and Standard Method 2130 B; chlorine uses USEPA 330.5 and Standard Method 4500-Cl G. Exclusive CAL CHECK™ supports chlorine verification and calibration. Tag identification, GLP features, 200-reading memory and RS232/USB PC interface are included. Supplied in a carrying case with five capped cuvettes, turbidity and chlorine standard kits, silicone oil, cleaning cloth, five i-Buttons with holder, batteries and AC adapter, this meter from manufacturer Hanna Instruments measures 224 x 87 x 775 mm and weighs 512 g.
