Calibration and support

INFRA S10/S11 measures air pressure directly for extremely reliable accuracy. All filtering and signal processing is performed digitally within the sensor. This allows you to keep your data logger working in the field while the sensor is sent for annual recalibration. Sigicom has calibration laboratories in Stockholm (Sweden), London (UK), Caen (France), Colorado (USA), and  Ottawa (CA). Read more about our calibration services under Support.


Environmental monitoring is a crucial part of our society and is performed within many construction and infrastructure projects. Air blast monitoring is important to ensure safety for surrounding structures and buildings. Making sure that nearby buildings are protected, and residents are comfortable, is a best practice in the industry.
