دستگاه کلرسنج CL17 HACH
مشخصات دستگاه
Accuracy:± ۵ % or ±۰٫۰۳ mg/L as CL₂, whichever is greater
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
Alarm: Two alarms selectable for sample concentration alarm, analyzer system warning, or analyzer system shut-down alarm. Each is equipped with an SPDT relay with contacts rated for 5A resistive load at 230 V AC.
Communication Capabilities: 4-20mA Output
Cycle Time: 2.5 min
Dimensions (H x W x D):454 mm x 314 mm x 179 mm
Display: LCD, 3-1/2 inch digit measurement readout and six-character alphanumeric scrolling text line
Drain: 1/2-inch ID flexible hose, hose barb
Enclosure Construction: ABS plastic, two clear polycarbonate windows, IP62-rated with the gasketed door latched.
Enclosure Rating: IP62
Includes: CL17 Chlorine Analyser with 1 Month Supply of Free Chlorine Reagents, Maintenance kit, Installation Kit, and Manual. (The power cord is ordered separately.)
Inlet: 1/4-inch OD polyethylene tube, quick-disconnect fitting
Inlet Pressure: 1 to 5 psi (0.07 to 0.34 bar), 1.5 psi (1.03 bar) is optimum
Interferences: Other oxidizing agents such as bromide, chlorine dioxide, permanganate and ozone will cause a positive interference. Hexavalent chromium will cause a positive interference: 1 mg/L Cr6+ = approximately 0.02 mg/L as Cl₂. Hardness must not exceed 1,000 mg/L as CaCO₃.
Light Source: Class 1 LED (light emitting diode) with a peak wavelength of 520 nm; 50,000 hours estimated minimum life
Lower Limit of Detection (LOD): 0.03 mg/L (ppm)
Mounting: Wall mount

Operating Temperature Range: 5 – 40 °C max.
Parameter: Chlorine, Free & Total
Power Requirements (Amps): 2.5 A
Power Requirements (Hz): 50/60 Hz
Pressure Range: Inlet Pressure to Sample Conditioning: 1.5 – 75 psi (0.1 – 5.2 bar)
Range: 0 – 5 mg/L Cl₂
Recorder Outputs: One 0/4-20 mA with an output span programmable over any portion of the 0 to 5 mg/L range. Recommended load impedance 3.6 to 500 ohms, 130 V isolation from earth ground.
Repeatability: 0.01 mg/L or 3.0 % , whichever is greater
Sample Flow Rate: 200 – 500 mL per minute minimum
