Advanced HACH LDO® Process Dissolved Oxygen Probe Breakthrough luminescent technology. Break-through luminescent technology for dissolved oxygen. The HACH LDO® Dissolved Oxygen Probe continuously monitors DO with this revolutionary method of detection. It’s virtually maintenance-free with no membranes to replace, no electrolyte solution to replenish, and no anode or cathode to clean or replace. No Calibration for 1 Year No drift, 99% Accurate LDO Technology No Membranes, Simple Installation and Maintenance Method of Detection Full Featured “Plug and Play” sc Digital Controllers No Calibration for 1 Year An internal standard calibrates the instrument with every reading. Factory calibration and membrane replacement are unnecessary. Periodic wiping of the sensor with a wet rag is all that is required for continuous measurement. No drift, 99% Accurate LDO Technology The sensor is unaffected by pH swings, hydrogen sulfide, wastewater chemicals, heavy metals, or organic build-up on the sensor. Warm-up time is unnecessary so the analyzer can start measuring within 30 seconds of when it’s turned on. No Membranes, Simple Installation and Maintenance The HACH LDO probe can be installed with a choice of pole or ball-float mounting kits. The probe has only one inexpensive replacement part—the sensor cap that is simple to replace. The sensor cap is warranted for one year. The probe is warranted for three years. Method of Detection The HACH LDO sensor is coated with a luminescent material. Blue light from an LED is transmitted to the sensor surface. The blue light excites the luminescent material. As the material relaxes it emits red light. The time for the red light to be emitted is measured. Between the flashes of blue light, a red LED is flashed on the sensor and used as an internal reference. Increased oxygen in the sample decreases the time it takes for the red light to be emitted. The time measurements correlate to the oxygen concentration. Full Featured “Plug and Play” sc Digital Controllers There’s no complicated wiring or set up procedures with the Hach sc100 controller. Just plug in any Hach digital sensor and it’s ready to use—it’s “plug and play.” One or two sensors—Use the sc100 Digital Controller to receive data from up to two Hach dig Specifications Accuracy: ± 0.1 ppm Below 1 ppm Accuracy 2: ± 0.2 ppm Above 1 ppm Accuracy 3: Measurement:± 0.2% of span Temperature:± 0.2 °C Cable Length: 10 m (33 ft) Calibration Method: Air Calibration: one point, 100% water saturated air; Sample Calibration: comparison to standard instrument, or comparison to Winkler Titration method Communication: Modbus Flow Rate: None required Hazardous Location Ratings: ETL listed (cETLus marked) to Canadian and US General Safety and Hazardous (Class l, Div. 2) Locations Interferences: No interferences from the following: H2S, pH, K+1, Na+1, Mg+2, Ca+2, NH4+1, Al+3, Pb+2, Cd+2, Zn+2, Cr (tot), Fe+2, Fe+3, Mn+2, Cu+2, Mi+2, Co+2, CN–1, NO3–1, SO4–2, S–2, PO4+3, Cl–1, Anion Active Tensides, Crude Oils, Cl2–1 Measurement Range 2: 0 to 20.0 mg/L Measurement Range 3: 0 to 200 % saturation Measuring range: to Operating Temperature Range: 0 to 50 °C Resolution: ± 0.07 ppm Below 10 ppm 1% saturation ± 0.1 % Below 10 ppm Response Time: at 20?C: To 95 % in less than 60 seconds Response Time - 20 °C: Hasta 90 % en menos de 40 segundos Hasta 95 % en menos de 60 segundos Sensor Immersion Depth: Pressure Limits at 107 m 1050 kPa (350 ft.), 1050 kPa (150 psi), maximum Sensor Thread: Inner thread Storage Conditions: -20 °C to 70 °C Transmission Distance: 1000 m (3280 ft.) maximum when used with a termination box Warranty: 3 years Weight: 3.09 lbs.
