4. Heated sampling system 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
By  using  a  heated sampling system (option)  is possible to measure 
water-soluble substances (NO

2

 and SO

2

) without washout. A built-in 

hot  gas  filter  protects  the  instrument  especially  for  long-term 
measurements from fouling. The maximum exhaust gas temperature 
when using the heated sampling system is 500 ° C. 

Please note: 
 
- Do not bend the tube 
- Heated tube has to be cooled out after the 
  measurement 
- Heated tube may not be folded too tight 
  (use the whole under case)  
- Do not put the heated tube in water 
- Clean or replace PTFE filter regularly
