دستگاه کلرسنج CL17 HACH
مشخصات دستگاه کلرسنج CL17 HACH
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.
