Dissolved oxygen meters
The Orion Lab Star pH meters allow simultaneous reading of pH, mV and temperature and include an electrode condition icon to determine the status of your pH electrode.
Lab Star meters can be calibrated using automatic buffer recognition or manual entry within the same calibration and pH, ORP and temperature calibration logs include date and time stamps.
The large backlit display screen features stabilizing and ready indicators to identify when measurements are complete. The meters have a small footprint and have a durable membrane keypad to support rugged lab use and disinfection needs.
