Safety Information
The module is used to measure oxygen in liquids and gases using an SE 740
series optical sensor. It measures the partial pressure of oxygen, air pressure,
and temperature simultaneously. It is also able to calculate and display the oxy-
gen saturation and concentration as well as volume concentration in gases.
The LDO 3400-170 / LDO 4400-170 module is not intended for operation in
locations subject to explosion hazards.
