Hydrolab

LDO

Since 2002, Hach has established itself as the premier provider of luminescent dissolved oxygen (LDO) technology, and only Hydrolab Series 5 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.

FEATURES

Features:

  • No membranes Calibrations that last Superior accuracy Compact housing allow complete integration into any sonde – DS5X, DS5, or even MS5 No glue, exposed fasteners, metal, seams, or moving parts

Benefits:

  • 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
