Hach LDO® Dissolved Oxygen Sensor
Since 2002, Hach has established itself as the premier provider of luminescent dissolved oxygen (LDO) technology. Only Hydrolab multiparameter sondes feature Hach LDO technology – designed, manufactured, and supported by Hach in Loveland, Colorado. Now in its second generation, the Hach LDO sensor for Hydrolab sondes is better than ever.
- Hach LDO technology with significant advantage over Clark cell DO sensors
- No membranes, so concerns about air bubbles, 24-hour membrane relaxation, and the art of maintenance are a thing of the past
- Calibrations with low drift, means that deployments will last longer, reducing frequency of trips to the field for maintenance
- Does not consume oxygen so passive fouling will not affect DO readings
