HiSense Gas Analysis

Unlike conventional exhaust gas analysis, the HiSense analysis systems from HiTec Zang also offer the biological variables OTR, CTR and RQ. The devices are suited for R&D and laboratory applications and for production and quality assurance.

Measuring equipment

Sensors are used for oxygen analysis which are distinguished by their low interference, low-noise readings and high long-term stability.

NDIR photometers with a minimum of zero and increase errors are used for the CO2 measurement. Through a new form of special measuring method even the precise measurement of very low activity both for small differences and for small measured gas flows are possible.


  • 2 to 5 measuring channels for up to 4 fermenters with a common gas feed or 2 fermenters with separate gas feeds
  • High-resolution measurement (HiSense-c)
  • Humidity correction / gas drying (HiSense-c)
  • "Genuine" OUR, CER and RQ measurement (HiSense-c)
  • Low interference
  • Overpressure possible
  • Wear-free sensors
  • Compact
  • Additional functions can be integrated
  • Optionally freely programmable
  • Many possibilities for couplings
  • Data export

Gmix Gas Mixture Stations

The Gmix precision gas mixture station was especially developed for applications which demand an extremely high degree of accuracy and reproducibility of the gas mixture.

The gas mixture station may be supplied in various configurations. The gas mixture of up to four gases can be individually adjusted for each output.

All gas inputs may be allocated as desired with the gases air, nitrogen, oxygen and carbon dioxide and are calibrated for these gases at the factory. Up to 10 gases can be calibrated per input. Other gases are possible on request. The units can be preselected to mln/min, ln/min and ln/h.

The Gmix gas mixture station is available both as an OmniFerm® and RAMOS® extension and as an independent system.


  • Best possible accuracy and reproducibility
  • Especially even dosing
  • Compact construction
  • Automatic monitoring and protective function
  • Self-explanatory user interface
