Chromatotec has engineered and manufactured the new Medor Exd designed to operate in hazardous area environment zone 1 without any purging system

Description :

The MEDOR Exd is an automatic and isothermal gas chromatograph dedicated to sulfur compounds analysis (H2S, mercaptans and sulphides) in different matrices.
Two versions exist :

• the MEDOR Exd ppm which measures at ppm levels
• the MEDOR Exd ppb which measures at ppb levels.

Principle :

• Hazardous area Ex d enclosure 
• Internal temperature and pressure monitoring
• Loop injection by automatic valve
• Detection is made by a gas-liquid reaction
• Sulfur specific detector – no interferencees
• The detector life is in excess of 10 years

Features :

• ASTM D7493-08 : Standard Test Method for Online Measurement of Sulfur Compounds in Natural Gas and gaseous Fuels
• Fully automatic, continuous online analyzer in an Ex enclosure
• Integrated industrial computer
• Storage of date & time stamped chromatograms

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
