Benchtop Dissolved Oxygen / RDO meter, suitable for all types of samples
It has a backlit LCD display that simultaneously shows the readings of:
Dissolved oxygen in percent saturation or concentration and temperature, plus date, time, sample and user identification and calibration report.
Simple operation through guided on-screen menus with key indicators for the user.
Automatic recognition of Polarographic probe and optical/luminescent RDO.
Software in Spanish.
AUTO-READ function.
Stable reading indicator.
Stores up to 1000 readings, associated with date and time, in its non-volatile memory.
Easy download of data to PC via USB port or RS232 port with the analysis software.
Possibility of incorporating a rod stirrer (code 096019, sold separately).
It works with a 220V mains adapter, but can also be powered with batteries (4 alkaline AA type).
IP54 splash-proof protection.
