Why the Aspida?

The Aspida is a robust, high specification personal carbon dioxide (CO) and/or oxygen (O) monitor which can be worn on a belt or even wall mounted as a backup to a primary safety system. Offering audio/visual alarms, data logging and a man down alarm for lone workers, it is an ideal solution to protect staff such as doctors, nurses and lab tech’s from the dangers of a leak of carbon dioxide (CO) or oxygen (O).

How it works

The Aspida  will alert users to any oxygen (O) levels above 23.5% with an audible and visual alarm, enabling them to take quick action to make the area safe.

The unit can be wall mounted at normal working head height in the gas storage room, or where enriched oxygen (O) is piped. The unit comes with one repeater as standard which is located at the entrance to the room.

What can it prevent?

The Aspida is ideal for safeguarding against carbon dioxide (CO) enrichment and oxygen (O) enrichment and deficiency. It has a high resolution display which gives clear readings in all light conditions and is packed into a durable, water resistant enclosure.

Up to date with Regulations

Standards such as EH40 in Europe mandate that employees are not exposed to potentially dangerous levels of carbon dioxide (CO) as it is a highly toxic gas in relatively small quantities. The Aspida is an affordable, easy to operate carbon dioxide (CO) monitor and is ideal for ensuring personal safety in the areas where gas is piped or stored. The same standards also require that consideration is given to asphyxiant dangers where inert gases such as nitrogen (N), argon (Ar) or helium (He) are used, a portable, personal monitor, like the Aspida, may be appropriate following a risk assessment.

Saving lives and rapid crisis response is at the heart of what we do. We design our systems in a way which enables you to focus on the job at hand, delivering the best possible care for your patients.

Users of the Analox Aspida will never need to worry about maintenance schedules again. The Aspida uses intelligent software which lets you know what requires maintenance and when - ensuring optimum performance of your unit. The software also allows 2 employees to share the unit, ideal for 24/7 split shift patterns. It is also the first gas alarm to incorporate a man down/panic alarm. The man down alarm will sound a loud (110 db) audible alarm in the event of an employee collapsing. Alternatively, an employee can trigger the alarm manually in a panic situation.


The Analox Aspida is a portable, personal, gas detection instrument capable of detecting potentially dangerous ambient levels of oxygen and carbon dioxide for protection of people working in confined spaces. The instrument gives clear audible, visible and vibration warning of potentially dangerous gas levels. A high resolution Organic Light-Emitting Diode (OLED) display shows clear, live gas level readings in all light conditions.

The Analox Aspida is available in three sensor configurations:
a) Carbon dioxide – single sensor
b) Oxygen – single sensor
c) Carbon dioxide and oxygen - dual sensor
