THT MEDOR : Odor measurement (THT)

THT MEDOR : Odor measurement (THT) Online analysis & control of gas odorisation

Description :

THT Medor is an online Gas Chromatograph dedicated to the analysis of THT present in different gases.
Two versions of the instrument exist : 

  • THT Medor ppm (measuring at ppm levels)
  • THT Medor ppb (measuring at ppb levels)

Principle :

  • Internal pressure & temperature monitoring
  • Sample loop injection is made by automatic valve
  • THT Medor uses a sulphur specific electrochemical cell for the detection of THT

Features :

  • Online, continuous sampling
  • No interference from other compounds
  • Low maintenance instrument – detector life may be up to 10 years
  • Automatic Validation of results by Internal Permeation Tube
  • Modifiable threshold alarms – High / Low alarm for odorising processes

VISTACHROM ® software : 
 Chromatotec developed software system enables :

  • Remote monitoring injection control
  • Full traceability with on board archiving of results
  • QC Set up and control of threshold alarms
  • Export of data MODBUS / MGS1 / 4-20mA / 0-10V
