Function and Applications
The Cobra4 Sensor-Unit pH and 2 x temperature NiCr-Ni is a
measuring recorder for pH, potential and temperature measurements,
which is controlled by micro-controller.
Benefits
- It can be fitted with two NiCr-Ni thermoelements (Type K) and a
pH probe or redox measuring chain
-
- Measure up to two temperatures and one pH or potential value
simultaneously.
- Discover new experimental possibilities especially in
thermodynamics
- Values of the calibration are saved in the sensor - no
need for new calibration.
- 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 or the Cobra4 USB-Link using a secure and
reliable plug-in/lockable connection.
