Typical Instrument Applications
♦ Respiration measurement

♦ Fermentation monitoring

The GIR250 is designed to monitor percentage
levels of oxygen and carbon dioxide in a single, robust
unit.
Based on our galvanic (electrochemical ) cell measuring
principle for oxygen measurement, and the infra-red
principle for carbon dioxide, the GIR250 provides a
permanent display of both gases up to a resolution of
0.01%. The instrument can be pre-programmed with
pass/fail criteria for each of the gases, and results can be
transferred to external recording/logging devices using
the 4-20mA outputs.
The key design philosophy is to provide a simple to
use, reliable instrument providing accurate repeatable
results over the whole of its range. Calibration is very
simple using the front panel keypad and can be carried
out with little or no training.
Cost of ownership is very low, containing a nondepleting infra-red sensor and a user-serviceable
replacement galvanic cell.
