What kind of samples can this analyser handle?

This type of analyser is designed for gas samples. It is crucial that the sample system avoids condensation and contaminants to ensure accurate readings and proper operation.

Is this unit suitable for continuous monitoring?

Units of this class can be used for both spot checks and continuous monitoring, especially when integrated with external logging or control systems via analogue outputs.

What is the typical power requirement for a unit like this?

Benchtop gas analysers commonly operate on standard mains power or a suitable DC supply, typical for laboratory equipment. Buyers should confirm the exact power specifications with the seller.

Can this analyser be used in hazardous environments?

The GIR250, as a standard benchtop unit, is not typically certified for use in hazardous (ATEX) environments. Buyers requiring such certification should look for intrinsically safe or explosion-proof models.

How easy is it to calibrate this gas analyser?

The design of this model emphasises ease of use, including simple calibration via the front panel keypad, which helps to reduce training requirements.

What is the expected lifespan of the O₂ sensor?

The lifespan of an O₂ galvanic cell varies depending on usage and gas concentration, but it is designed to be user-replaceable, allowing for straightforward field maintenance.

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 type of analyser is designed for gas samples. It is crucial that the sample system avoids condensation and contaminants to ensure accurate readings and proper operation.

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.
