FAQs

Can I wear the ALTAIR Single-Gas on my PPE?

Absolutely. It comes with a rugged, stainless-steel suspension clip as standard. Small and lightweight at only 85g, it can be clipped to a lapel, pocket, or high-vis vest without being intrusive or weighing the worker down.

What makes the ALTAIR Single-Gas “maintenance-free”?

The unit is designed as a “disposable” monitor with a guaranteed two-year service life. It requires no sensor changes, battery charging, or calibration during its lifespan. Once activated, it stays on continuously, making it a hassle-free option for busy UK sites.

Which gas versions are most common for UK construction?

The unit comes in Oxygen, Carbon Monoxide, and Hydrogen Sulphide versions. CO units are common for workers near fuel-powered machinery, while O2 units are essential for detecting displacement in deep excavations to ensure atmospheric safety.

Is there a version that can be serviced rather than disposed of?

Yes. While the standard ALTAIR is maintenance-free, the ALTAIR Pro and ALTAIR 2X models are available for those preferring a maintainable fleet. These feature replaceable sensors and batteries, making them a better choice for long-term ownership.

How does the unit handle the wet and muddy conditions of a UK groundworks site?

The ALTAIR is exceptionally rugged, featuring an IP67 rating for dust and water ingress. It is encased in a thick, rubberized armor housing and is tested to survive a 3-metre drop onto concrete, ensuring durability during daily site life.

What kind of alarms does it have?

It features a “Triple Alarm” system to ensure it is noticed over heavy machinery noise: a piercing 95 dB audible alarm, super-bright flashing LEDs visible from 320 degrees, and a strong internal vibrating alarm.

How do I perform a “Bump Test” on this unit?

A single button press enters “Gas Test” mode. After applying a quick burst of test gas, the unit confirms the sensors and alarms are working. A checkmark icon then appears on the display for 24 hours to show compliance.

Does it record alarm events for safety audits?

Yes, the unit automatically records the last 25 alarm events. This data can be downloaded via an IR link to a PC, providing safety managers with a clear digital record if a gas incident occurs on-site.

How is the ALTAIR Single-Gas used to comply with UK safety law?

Under Confined Spaces Regulations 1997 and COSHH, employers must provide sufficient means for detecting hazardous atmospheres. For specific risks, like CO from generators, this unit provides a calibrated solution to meet HSE EH40 exposure limits.

Does PQS Survey Ltd offer hire, service, and repair for single-gas units?

Yes. We stock single-gas units for immediate hire nationwide. While the maintenance-free version is not repaired, we provide full service for the maintainable Pro and 2X ranges. All hire units include a fresh calibration certificate for UK compliance.
