Portable pH/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.
Power supply: 4 AA alkaline batteries.
IP67 splash-proof protection.
