Dissolved Oxygen Analyser OD7685
The instrument can be configured for a polarographic or galvanic oxygen cell with direct connection or via micro transmitter mod. 080610.2. It is designed for manual and automatic temperature compensation using a thermoresistance integrated in the cell. The instrument also provides temperature measurement. Instrument manufactured in robust aluminium enclosures DIN 43700, with front panels in polycarbonate. Their reliability and precision, along with their functionality, make them easy to use in all applications.
