What are the benefits of using an LDO® (Luminescent Dissolved Oxygen) over a Polarographic Dissolved Oxygen (PDO) probe?
LDO® versus Polarographic Dissolved Oxygen probes.
LDO® probes have a 3 year warranty compared to the 1 year warranty the PDO probes have.
LDO® probes can be stored dry, unlike the PDO probes which need to be stored in a storage solution.
LDO® probes do not have electrolyte filling solutions or membranes that need to be replaced regularly. They only have a sensor cap that needs to be replaced just once per year.
LDO® probes do not need to be polarized for several hours before use. They can be used right away.
LDO® probes are available in rugged style which has a 5 meter (or longer) cable that is much sturdier than the PDO probes and can be used in full submersion applications.
LDO® probes have a built in barometer to measure pressure compared to the PDO probes which require this to be estimated and entered manually.
