Oxygen and carbon dioxide analyser (Bench Top) - GIR250 - 1

GIR250 dual range analyser for oxygen and carbon dioxide What it gives you ♦ Dual measurement of oxygen and carbon dioxide in one instrument Compact, robust unit Transportable laboratory style case Simple, easy to read display Intuitive user interface Easy calibration process Pump and flowmeter for sample control Comprehensive set of programmable alarm relays and analogue outputs Real time results Fast sensor response Typical Instrument Applications ♦ Respiration measurement 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. ♦ Douglas bag analysis Ease of use and reliability—a good combination.
