Description
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
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.”
