Cobra4 Sensor-Unit pH, BNC connector

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.
