Onsite Calibration

Fixed Gas Detection Systems Calibration

Most of the sensors used in fixed toxic gas detection systems are electrochemical in nature.  That means that they are lined with a special coating that causes a change in voltage when exposed to it’s target gas.  As the sensors age these changes in voltages begin to drift and the sensor may begin to read gas concentrations incorrectly.  For these reasons, manufacturers suggest frequent calibration and testing of the sensors and detectors.  

We offer monthly and quarterly routine calibration services. Routine calibration means that your sensors will perform as designed and that you will have proof that your health and safety devices are actually protecting your employees.  All Hawk Equipment Services calibrations come with a signed calibration certificate and calibration sticker.  We only use NIST traceable span gases, so you can be assured that your system is calibrated as per the manufacturer’s specifications.
