Hitech Instruments GIR250 Benchtop and Portable Oxygen & Carbon Dioxide Gas Analyser

The Hitech Instruments GIR250 is a rugged, bench‑top and transportable gas analyser designed for simultaneous measurement of oxygen (O₂) and carbon dioxide (CO₂) in gas samples. It supports critical applications such as bioprocess monitoring, respiratory gas analysis, and gas mixture quality control in biotechnology and clinical diagnostics.

Key technical features include:

• Dual gas detection for O₂ and CO₂ within percentage ranges, suitable for fermentation and bioprocess environments
• User-programmable pass/fail alarm criteria for each gas to enhance operational safety and process control
• Analog outputs (4–20 mA) compatible with external data logging and automatic control systems, facilitating integration in biomanufacturing workflows
• Simple front-panel keypad calibration to minimize operator training and downtime
• Field-replaceable galvanic O₂ sensor cell for low-maintenance operation, reducing total cost of ownership
• Rugged, lab‑style transportable housing with 0.25″ (~6 mm) sample tubing connections, allowing both benchtop and mobile use

Operational parameters include a non-condensing sample environment at ambient temperatures from –5 to +40 °C, emphasizing suitability for laboratory and in-field monitoring. The analyser is particularly valuable in molecular diagnostics, synthetic biology, and bioprocessing applications where continuous and reliable O₂/CO₂ quantification is essential.

The GIR250 is not designed for trace ppm-level gas detection but excels in percent-range gas analysis crucial for live-cell imaging studies, fermentation control, and process gas inertisation in biotechnology research and clinical respiratory gas analysis.

This instrument aligns with the demands of researchers and professionals requiring precision oxygen and carbon dioxide monitoring integrated within biotechnological and clinical diagnostic laboratories.
