Hanna HI93414 Turbidity and Chlorine Portable Meter

HI 93414 adalah alat ukur multiparameter berakurasi tinggi untuk turbidity dan chlorine. Instrumen ini adalah kombinasi dari nephelometer dan fotometer untuk mengukur parameter yang paling penting dalam air minum: kekeruhan (turbidity) dan klorin. Instrumen ini disediakan lengkap dengan AMCO-AEPA-1 standar kekeruhan primer dan NIST standar klorin sekunder digunakan untuk kalibrasi dan verifikasi kinerja.
Hanna HI 93414 memenuhi dan melebihi persyaratan EPA Method 180.1 dan Metode Standar untuk Pemeriksaan Air dan Air Limbah 2130 B untuk pengukuran kekeruhan. Dan untuk pengukuran klorin disesuaikan Metode EPA 330,5 dan Metode Standar 4500-Cl G.
