Our accreditation allows us to perform flow and gas concentration calibrations both off-site and on-site calibrations.
Calibration of ambient air analysers that measure the concentration of pollutant gases in ambient air:
· SO2 analysers
· NO analyzers
· NO2 analyzers
· CO analysers
· O3 analyzers
· SH2 analyzers
· Benzene analysers
Gas flow rate
Calibration of flow meters and flow controllers used in ambient air quality monitoring:
· Direct measuring flowmeters
· Mass flow controllers
· Particulate matter samplers
· Flowmeters with electrical output
· Breathing flowmeters
Off-site ENAC Calibration
Our Off-site ENAC accredited laboratory allows accurate and complete calibrations to be performed in a specialised environment and controlled conditions. This provides greater stability in instrument measurements, tending to require less frequent calibration.
On-site ENAC Calibration with mobile laboratory
Thanks to our mobile calibration laboratory, Envira is able to carry out on-site calibrations that take into account the specific conditions of the environment in which the instrument is used, in order to adjust or verify its accuracy. It also makes it possible to correct deviations caused by environmental factors or wear and tear over time more quickly and without interrupting production processes for more than a short period of time.
Maximum measurement accuracy with precise and reliable data.
Compliance with standards and regulations, guaranteeing quality, safety and environmental standards.
Traceability and traceability to recognised national and international standards.
Correct maintenance and upkeep of instrumentation.
Optimization of processes and resources by obtaining accurate information.
Safety and prevention of risks associated with measurement deviations.
Dispute support and product warranty.
International recognition that facilitates access to new markets.
We have more than 17 years of demonstrable experience and technical expertise in the management of most of the analyzers of the air quality networks in Spain.
The accreditation granted by ENAC in accordance with the EN 17025 standard confirms the competence of our laboratory and staff, who are subjected to strict quality controls to guarantee the traceability and reliability of the results of our calibrations.
We specialize in gas proficiency testing programs to form part of air quality networks and laboratories.
