Function and Applications
The Cobra4 Sensor-Unit pH, BNC connection is a measuring
recorder for pH measurements, which is controlled by
micro-controller.
Benefits
- It can be fitted with a pH probe, in order to measure pH
values.
- Values of the calibration are saved in the sensor - no
need for new calibration after changing the basic unit.
- The sensor is not restricted to the measurement of pH values:
Connect the redox electrode 46267-10 to measure redox
potentials.
- The unit can be connected to the Cobra4 Wireless-Link, the
Cobra4 Mobile-Link, the Cobra4 Junior-Link or the Cobra4
USB-Link using a secure and reliable plug-in / lockable
connection.
