    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.

    Air and gas measuring devices for air quality and safety

    Air and gas measuring devices detect gases, vapours and airborne pollutants and are used to assess indoor air, industrial processes and occupational safety. This category includes portable gas detectors, indoor air quality meters and stationary sensors for CO2, CO, O2, VOC, combustible gases and other components.

    Measurement principles and sensor types

    Electrochemical, NDIR infrared, catalytic and PID sensors cover a wide range of toxic and combustible gases. Particle and fine dust sensors measure PM2.5/PM10, while multifunctional devices additionally record temperature, humidity and differential pressure to characterize ambient conditions.

    Portable air and gas measuring instruments

    Portable multi-gas detectors are ideal for occupational safety, maintenance and service. Visual and audible alarms warn if preset thresholds are exceeded, and data logging functions document exposure over time. Indoor air quality meters support the evaluation of CO2 levels, VOC load and comfort parameters in offices, schools and public buildings.

    Stationary gas detection and air quality systems

    Stationary sensors and controllers continuously monitor critical areas such as car parks, refrigeration systems, storage rooms and laboratories. Analogue 4–20 mA or digital interfaces connect the sensors to ventilation systems, building automation and safety systems.

    Typical applications

    Applications range from building services and chemical industry to biogas plants, wastewater treatment and environmental monitoring. Air and gas measuring devices contribute significantly to compliance with limit values and to the optimization of ventilation concepts.

    Selection criteria

    Key criteria are the target gases, measuring ranges, alarm levels, sensor lifetime and environmental conditions. For portable instruments, battery life, robustness and ease of use are crucial, while stationary systems require suitable maintenance and calibration concepts and flexible interfaces.
