- In the course of our LEV surveys we use analogue TA2 anemometers, digital pressure meters, dust lamps and smoke testers.
- A digital particle sampler is used for return air sampling where necessary.
- All our meters are calibrated annually and are checked between calibrations by comparing their readings to the latest calibrated meter. In this way a meter that has become less accurate, is soon identified and is recalibrated.
- Pitot tubes and digital pressure meters are used where highly accurate airflow measurements are required. For example when calibrating production plant and for test equipment.
