The HI93414 is a high accuracy Turbidity and Chlorine Portable Meter. This meter is a combination of a nephelometer and photometer to measure the most important parameters in drinking water: turbidity and chlorine. The meter is supplied complete with AMCO-AEPA-1 primary turbidity standards and NIST traceable secondary chlorine standards used for calibration and performance verification. The HI93414 meets and exceeds the requirements of EPA Method 180.1 and Standard Methods for the Examination of Water and Wastewater 2130 B for turbidity measurements.The chlorine measurements are are adapted EPA Method 330.5 and Standard Method 4500-Cl G.
