Wireless thermocouple sensor

The CMA wireless thermocouple sensor is designed to measure high and low temperatures in a wide range from -200 to +1200 °C. It uses a Type K thermocouple, making it suitable for experiments such as flame temperature measurements and ignition point detection.
The thermocouple sensor is equipped with an OLED color display which shows sensor information and the measured values. This makes the sensor suitable to use as an independent measuring instrument.

The thermocouple sensor can be used wirelessly via Bluetooth or wired via USB with the Coach 7 or Coach 7 lite programs/apps on computers (Windows and Mac), Chromebooks and mobile devices (Android and iOS).

Technical specifications:

• Measuring range: -200 .. 1200 °C

• Warrantee: 36 months
• OLED display: 0.96” 128 x 64px
• Maximal sampling rate: 4 Hz
• Battery life: 8h when full (rechargeable)
• Connection: Bluetooth 5, Low Energy (Mac, Android, iOS) Bluetooth 2.1, Classic (Windows) or USB-C 2.0

All specifications of the sensor are described it its Product manual.

Suggested physics and chemistry experiments:

• Low temperature experiments (< 0?°C)
  • Compare freezing points of pure water and saltwater solutions
  • Record the temperature profile of water, ethanol, or oil as they are cooled below 0?°C
• Moderate temperature measurements (0 to 150?°C)
  • Measuring freezing and boiling points
  • Specific heat experiments
  • Measurement of breath temperature
• High temperature measurements ( > 150?°C)
  • Measure temperature at different regions in a Bunsen burner or candle flame (inner cone, outer cone, tip)
  • Measure ignition temperature of materials paper, wood shavings or cooking oil
  • Heat one end of a metal rod with a flame and record the temperature gradient along the rod
  • Experimentally determine the melting point of copper, bismuth, or other solids
