Portable 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, probe status, user ID, sample ID and calibration points.                       
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.                   
Stores up to 5000 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. 
It works with batteries (4 alkaline AA type), although it can also be powered with a 220V mains adapter. 
IP67 splash-proof protection.
