EPA-approved Free or Total Chlorine Analysis

Hach’s CL17 Chlorine Analyzer is compliant with US EPA Regulation 40 CFR 140.74, and both Method 4500-CL G and Method 334.0 can be used for measurement of residual chlorine in drinking water.

Accurate, Reliable Results

The Hach CL17 is the industry standard for online chlorine monitoring. It comes factory-calibrated and does not require recalibration unless specified by your regulatory agency. The CL17 analysis method is not affected by changes in chlorine concentration, sample pH, temperature, flow, or pressure, resulting in better accuracy than other online chlorine testing methods.

Simple, predictable maintenance

The CL17 can operate unattended for up to 30 days. Monthly preventative maintenance can be performed in 15 minutes or less and requires no special tools.

What's in the box?

CL17 Chlorine Analyser, Maintenance kit, Installation Kit, and Manual. (The power cord is ordered separately.)


Accessories: Installation Kit
Maintenance Kit
Accuracy: ± 5 % or ±0.03 mg/L (ppm) as CL₂, whichever is greater. *For permanganate accuracy, please refer to permanganate application notes
Air purge: 0.1 cfm (0.17 m³/h) instrument quality air at max. 20 psig (ca. 1.4 bar) with 1/4-inch OD tube, quick disconnect fitting
