HACH ONLINE, CL17 Free Chlorine Analyzer
CL17 menggunakan kimia colorimetri DPD untuk memantau konsentrasi residu dan total klorin secara terus menerus. CL17 merupakan solusi sederhana, dapat diandalkan dan ekonomis serta pilihan yang lebih disukai untuk instrument “high-maintenance” yang membutuhkan frekuensi kalibrasi tinggi. Metode analisa CL17 “robust” dan tidak terpengaruh oleh perubahan konsentrasi klorin, pH sampel, suhu, arus atau tekanan sehinga menghasilkan akurasi dan reabilitas yang tinggi. Pemeliharaan rutin bulanan untuk CL17 biasanya dapat dilakukan dalam 15 menit, termasuk penggantian reagent dan pembersihan sel colorimetri. Tidak membutuhkan waktu khusus. Dalam penggunaan normal CL17 akan beroperasi tanpa pengawasan selama 30 hari. EPA Compliant CL17 ini kompatibel dengan US EPA peraturan CFR 140.74 dan kedua metode 4500-CL G dan metode 334.0 dapat digunakan untuk pengukuran residu dan total klorin dalam air minum.
