Continuous Gas Analyzers
Continuous gas analyzers based on thermal conductivity (TC) detectors are our specialty. These types of instruments are variable and can easily be adapted for your needs.
The high precision analyzers are small dimensioned, so it is possible to mount them on individual sample points in a facility.
AGIMAS analyzers do not need additional gases or other consumables for measurements of any gases even including infrared inactive gases.

• Multi Gas Mode allows sequential indication of up to 15 binary mixtures
• Isolated 4-20mA output, expandable; free set of start and end within 100 Vol.% range
• Classic 2-point calibration or simple one-gas calibration
• Free set of display indication (ppm or Vol.%) at a resolution up to 1ppm
• Cross sensitivity compensation by feed in of external signal and internal calculation
• Fast response with a T90-time of less than 1 sec (depending on flow rate)
• Pressure proof (20bar) and vacuum leak tight stainless steel (LF316i) gas duct
• Three isolated relays for indication of alarms and instrument status
