What gases can this analyser measure?

This model is designed to measure oxygen (O₂) and carbon dioxide (CO₂) simultaneously. Buyers should confirm the specific gas ranges with the seller.

Is this unit suitable for continuous monitoring?

While designed for reliability, the GIR250 is typically used as a bench-top or transportable analyser for batch sampling or intermittent monitoring. For continuous, long-term process monitoring, buyers should discuss specific application requirements with the seller.

What kind of sample preparation is required?

The analyser requires a non-condensing sample environment. It is crucial to ensure the sample gas is free from particulates and moisture to prevent damage and ensure accurate readings.

How is the unit calibrated?

Calibration is typically performed via the front panel keypad, designed for ease of use. Specific calibration gas requirements should be confirmed with the seller.

Can this analyser be integrated with other control systems?

Units of this type commonly feature analogue outputs, such as 4-20 mA, which allow for integration with external data logging or process control systems. Buyers should verify the available outputs on this specific unit.

What spare parts are typically needed for maintenance?

The O₂ galvanic cell is a user-replaceable consumable item that will require periodic replacement. Other maintenance items may include filters or tubing, depending on usage and sample quality.

This listing is for the Hitech Instruments GIR250 Gas Analyser The unit is in full working condition and is ready for immediate use The GIR250 is a bench‑top / transportable analyser designed to measure oxygen (O₂) and carbon dioxide (CO₂) simultaneously in gas samples. It is made by Hitech Instruments (now part of the MTL / Eaton group). Its design emphasizes ease of use, reliability, and low maintenance cost. Other supporting features: The instrument can be programmed with pass/fail criteria for each gas (alarms). It provides analog outputs, typically 4–20 mA, for external logging or control systems. Calibration is designed to be simple (via the front panel keypad) to reduce training burden. The O₂ galvanic cell is user-replaceable (i.e. maintenance can be performed in the field). Mechanical, Electrical & Operational Details The GIR250 is housed in a rugged, transportable case (lab-style) so it can be used as a benchtop or mobile analyser. Sample inlet and outlet connections use 0.25″ (~6 mm) tubing. The sample system should avoid condensation and contaminants; non‑condensing sample environment is required. Operating ambient temperature: –5 to +40 °C (for non‑condensing conditions) Power / interface: standard for bench‑top analysers (the catalogue doesn’t always detail it, but likely mains or DC supply, suitable for lab use) Typical Applications & Suitability Because it can measure both O₂ and CO₂ in a single unit, the GIR250 is used in applications such as: Respiration / breathing gas analysis / Douglas bag analysis (i.e. in physiological or experimental gas mixture measurement) Fermentation / bioprocess monitoring (where O₂ and CO₂ both matter) Gas mixture / inertisation / process gas quality (checking gas purity, calibrating mixtures) It is not primarily intended for measuring very low trace levels (ppm-level) of O₂ or CO₂ unless its ranges are suitably adapted or specified. The design is more for percent-range analysis

This model is designed to measure oxygen (O₂) and carbon dioxide (CO₂) simultaneously. Buyers should confirm the specific gas ranges with the seller.

Gas analyzers and detectors are regarded as essential precision instruments in pharmaceutical and biotech laboratories. Buyers typically prioritise calibration records and maintenance history when purchasing used equipment. These instruments are valued for their accuracy, repeatability, and reliability in critical analytical processes. Key considerations include ensuring proper documentation of service intervals, verifying sensor functionality, and confirming compatibility with existing laboratory systems. Well-maintained units often perform comparably to new equipment at considerably lower cost, making them attractive for budget-conscious facilities requiring validated analytical capability.
