Digital Intelligent pH/mV/EC/TDS Meter |
|
Type : 50300 |
|
Description 
The 50300 is a multi-purpose and economical portable meter with RS-232 output. A range of probes for measurement of pH, conductivity, temperature, Dissolved Oxygen and Total Dissolved Solids are available. Each probe has built-in signal conditioning so scaling or calibrating of the instrument is not required and the correct units of measurement are automatically displayed.
