Oxygen – O2

Find here the essential information on dioxygen (O2) or oxygen: characteristics, effects on health, detection devices & systems – O2 monitor or rather oxygen depletion sensor – and respiratory protective equipment (self-contained breathing apparatus and supplied air respirator).

O2 monitor portable gas detector and sensors with oxygen respiratory protection

Oxygen properties

Dioxygen (O2) – which is most commonly known as oxygen – is a gas naturally present in the atmosphere at around 20%. It is essential to almost any form of life on Earth. This highly reactive gas can easily produce compounds (particularly oxides) from elements except for noble gases like helium or neon.

Oxygen effects on health

Oxygen (O2) is a colorless, odorless and tasteless gas that composes breathing air at 10.9%. In contrast to the great majority of gases, the lower the oxygen (O2) concentration is, the higher are the risks for health. In the medicine field, O2 is inhaled primarily in case of asphyxia, intoxication to carbon monoxide, or to treat acute pulmonary edema… This gas is not measured in ppm but in % volume.

Effects of oxygen levels: why use a portable O2 monitor

Effects of oxygen levels (O2) on health

Oxygen gas O2 monitor

As oxygen is colorless and odorless, this gas cannot be detected without proper equipment. Only an O2 monitor (oxygen depletion sensor) can accurately measure concentrations of oxygen in the air. Thus it is recommended to use an oxygen detection device in % volume.

Additional information

The GASBADGE PRO toxic gas detector is a classic single-gas detector. Its long-duration battery operates for about 2,600 hours and can be replaced when used. As for any other classic single-gas detectors, it is highly recommended to calibrate the GASBADGE PRO twice a year to ensure proper operation.

The GASBADGE PRO toxic gas monitor is a classic single-gas detector with interchangeable sensors and features a large range of electrochemical sensors. This technology is designed to detect toxic gases: Cl2 (chlorine), ClO2 (chlorine dioxide), CO (carbon monoxide), HCN (hydrogen cyanide), H2 (hydrogen), H2S (hydrogen sulfide), NH3 (ammonia), NO2 (nitrogen dioxide), O2 (oxygen), PH3 (phosphine) and SO2 (sulfur dioxide).

The GASBADGE PRO has 3 alarms: a powerful 95 dB audible alarm to alert even in noisy environments, a red LED visual alarm for view alert signals even in the darkest places like confined spaces and a vibrating alarm.

These alarms will be triggered by 4 events: if the lower or the upper limit values are reached, if concentrations get over the occupational exposure limit or if the average value threshold is exceeded. Abnormal gas concentrations and other data can also be saved and downloaded from the device.

Compact and lightweight, the GASBADGE PRO toxic gas detector is made with a strong polycarbonate housing with a robust and waterproof over-mold in compliance with IP67 protection. The GASBADGE PRO is ATEX approved as well for explosive atmosphere under current EU standards.

Additional information

The Ventis-MX4 is a portable multigas detector. Contrary to single-gas detectors, it can detect up to 4 gases. Thanks to its rechargeable Li-ion battery, it can continuously operate during around 12 hours at 20°C ambient temperature. This battery can be replaced by an optional extended battery for up to 20 hours of autonomy without pump.

The Ventis-MX4 portable gas detector can detect up to 4 gases amongst explosive gases, oxygen (O2), carbon monoxide (CO), hydrogen sulfide (H2S), sulfur dioxide (SO2) and nitrogen dioxide (NO2). A specific location is dedicated to the explo sensor (catalytic sensor) and the oxygen sensor (electrochemical sensor). A 4 gas unit will basically include oxygen and explo sensors.

The Ventis-MX4 features 3 different alarms. The first one is a powerful 95 dB at 30 cm audible alarm to alert in noisy environmets. A high visibility red LED visual alarm and an ultra- vibrating alarm are added to improve safety. Two alarm levels are configures: low and high alarms – which are basically calibrated under occupational safety at work data.

The Ventis-MX4 portable gas detector also features the same physical properties – dimension and weight – than a single-gas detector. It can be wore close to the breathing tracts thanks to its crocodile clip without disturbing the user. This multigas detector shock-resistant and waterproof thanks to its high visibility polycarbonate-made overmold.

As this device can detect explosive gases, it meets current EU ATEX standards (explosive atmosphere). A sampling pump – VSP for Ventis-MX4 – is available to draw remote samples (up to 30 meters) before interventions – e.g. in confined space.
