Air & Gas Measuring Instruments for Air Quality & Gas Monitoring – CO₂ Monitors, Gas Detectors & Sensors

We offer various air and gas measuring instruments such as CO₂ monitors, air quality meters, portable gas detectors, radon monitors, VOC detectors as well as stationary sensors for CO₂, CO, O₂ and other gases. In addition, you will find instruments for air sampling, flow measurement and weather & climate monitoring.

Depending on the instrument, they can measure CO₂, CO, O₂, ozone, VOCs, radon and other gases and airborne pollutants. Many devices also record temperature and humidity to provide a comprehensive assessment of indoor air quality. The exact measuring parameters are listed in each product description.

Air quality meters are mainly used to assess indoor air, e.g. CO₂ level, temperature, humidity and sometimes particulate matter or VOCs, often including trend graphs and threshold warnings. Gas detectors are primarily safety-related devices that give clear alarms when limit values are exceeded (e.g. CO, oxygen deficiency, flammable gases) and can be integrated into safety systems.

For which applications are PSE Priggen’s air and gas instruments suitable?
Our instruments are used in offices, schools, public buildings, industrial plants, laboratories, production areas as well as in building biology and environmental applications. Typical tasks include monitoring indoor air quality, controlling CO₂ levels, detecting hazardous substances and supporting occupational health and safety measures.

Yes, we supply portable handheld instruments for mobile measurements and spot checks, as well as stationary sensors and monitors for continuous monitoring of rooms or processes. Some models feature data logging capabilities, PC or network interfaces and alarm/relay outputs to control ventilation or warning systems.

Regular calibration or function checks are recommended for reliable readings, especially for safety-related gas detectors. The recommended intervals depend on the device type, application and manufacturer’s specifications. The technical data and manuals provide information on calibration – we will be happy to help you choose suitable instruments and calibration services.

Key criteria include the gases/parameters to be measured, measuring range, accuracy, response time, operating environment (indoor, industrial, possibly hazardous area), mounting type (portable or stationary) and required interfaces and alarm functions. If you briefly describe your measurement task, we will recommend suitable instruments and accessories.

Yes, we are happy to assist you in selecting suitable instruments and sensors for your application – from simple CO₂ room monitoring to combined solutions with several sensors. If desired, we take into account room size, number of occupants, ventilation concept and safety requirements and recommend a technically sound and cost-effective solution.
