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
