Hach IntelliCal LDO101 Rugged LDO Probe LDO10105

Hach rugged IntelliCAL Luminescent Dissolved Oxygen (LDO) probes use patented luminescent DO technology that does not need to change or replace membranes, no electrolyte solution to replenish, and reduces calibration frequency. Just replace the sensor cap about once a year. This LDO probe (comes with 5m cable length) is designed for use with Hach HDd series meters.
