Submersible Temperature Sensor TSUB21

  • Submersible Pt100 temperature sensor
  • Used in combination with optical meters for temperature compensation of optical sensors 
  • Teflon coated sensor tip and cable
  • Applicable in corrosive media like sea water
  • Applicable in approved organic solvents
  • 2.1 mm tip diameter

This temperature sensor is operated at the temperature port of optical meters. It allows an automatic temperature compensation for optical sensors in samples with varying temperatures. The complete sensor tip including its cabling is coated with Teflon specified for long-term submersion in aggressive media (e.g. sea water, approved organic solvents). The cable is very flexible (only 1.5mm in diameter) allowing its application in complex geometries.
