There is virtually no maintenance with Hach’s breakthrough luminescent technology. There are no membranes to replace, no electrolyte solution to replenish, and no anode or cathode to clean.
Customisable service indicators trigger a service message so that a cleaning cycle is never missed.
A cutting-edge, 3D calibration procedure at the factory makes oxygen measurement with the Hach LDO probe more accurate than ever before. A robust new design gives the Hach LDO enhanced durability and reduced size for easier handling.
