Gas probe is immersed in the gas duct and is supposed to extract the gas sample and to measure its temperature. Probes differ in length, diameter, range of work temperature, material and thermocouple type. Probes can be easily connected to probe holders and to heated hoses. Following types of gas probes are delivered:

  1. Regular inox (stainless steel) gas probes
  2. Strengthened inox gas probes
  3. Gas probe with in situ filter
  4. Ultrahigh temperature ceramic gas probes

Way to use

Mounting the probe pipe to the probe holder
  1. Insert the tip of the probe pipe into the holder’s hole and push it until it stops.
  2. Mind the thermocouple’s pins to slide gently in their positions and do not bend!
  3. Tighten up the probe pipe’s sleeve.


Fixing the gas probe to the duct’s wall with a fixing cone

Attention: while installing the probe on the stack always use protective gloves!

Loosen the wing screw on the fixing cone and move it towards the probe holder.

  1. Immerse the probe pipe on the desired depth via the hole in the duct’s wall. Use the probe pipe of an appropriate length, so the segment outside the stack is as short as possible.
  2. Move the fixing cone towards the duct’s wall and tighten it until it fits securely in the wall. It is advised to use a wrench.
  3. Secure the probe pipe on the cone by securing the wing screw.
