Function and Applications

The Cobra4 Sensor-Unit 2 x Temperature NiCr-Ni is a temperature probe, which is controlled by a micro-controller.


  • It can be fitted with two NiCr-Ni thermoelements (type K), in order to measure up to two temperatures simultaneously or to measure a temperature difference
  • The Cobra4 Sensor-Unit 2 x Temperature NiCr-Ni can be connected to the Cobra4 Wireless-Link, the Cobra4 Mobile-Link, the Cobra4 USB-Link or the Cobra4 Junior-Link using a secure and reliable plug-in / lockable connection.

Equipment and technical data

  • Temperature measuring range: -200..+1200 °C
  • Resolution: 0.1 K
  • Measuring accuracy: equal to the accuracy of the gauges used
  • Data flow rate: 5 Hz
  • Dimensions: approx. 62 mm x 63 mm
  • Weight: 85 g


For the measurement of temperature the following accessories are needed:

Thermocouple NiCr-Ni -40...+500° C single type, 13615-02
or Thermocouple NiCr-Ni -50...+1100° C microsheath, 13615-01
or Immersion probe NiCr-Ni -50...+1000° C stainless steel, 13615-03
or Immersion probe NiCr-Ni -50...+300° C Teflon, 13615-05
or Surface probe NiCr-Ni up to +1000° C stainless steel, 13615-04
