CarboProbe LT (%O2) low temperature probe, working temperature from 50°F to 1100°F


For use in flues and boilers, below 1100°F (600°C) The CarboProbe LT is a low temperature heated probe, intended for use in flues and boilers where the temperature of the gases are below 1100°F (600°C). It incorporates a heater to maintain the sensor at its working temperature, even if the gas is at a much lower temperature.

Key features

  • Based on the ZRO2 zirconia oxygen sensor
  • Heater sealed in a stainless steel can, isolating it from corrosive flue gases
  • Porous stainless steel filter to minimise dust build-up on the sensor
  • Gas inlet for calibration gases Purge facility, to clean the filter in-situ
  • Modular construction for simple maintenance
  • Compact design (diameter of 50mm), allowing installation in small or large flues Integrated K thermocouple, enabling accurate temperature control of the heater


The LT probe requires a separate instrument panel providing power and temperature control for the heater, purge timing and purge gas.
