Contact Hach
No Calibration Required
The Hach LDO probe uses luminescent dissolved oxygen technology. Traditional DO probes require DO sensor calibration, which increase maintenance requirements.
No Membranes to Replace
There is virtually no maintenance with Hach's breakthrough luminescent technology, as there are no membranes to replace, no electrolyte solution to replenish, and no anode or cathode to clean.
No Missed Cleaning Cycles
The Hach LDO probe is equipped with Prognosys, a predictive diagnostic system, that allows you to be proactive in your maintenance by alerting you to upcoming instrument issues. Know with confidence whether changes in your dissolved oxygen level measurements are due to changes in your instrument or your water. To make sure routine cleaning cycles are never missed, the probe offers operators customizable diagnostic alert indicators, ensuring the probe can operate at its maximum performance level.
Customizable service indicators trigger a service message so that a cleaning cycle is never missed.
No Drift
Cutting-edge 3D calibration procedure is conducted prior to shipping, the DO probe will not drift and is more accurate than ever before.
No Complications
Our newest DO probe has a robust design with a smaller footprint allows for easier handling with enhanced durability.
