Testo Industrial Services presents itself as a full-service provider for metrological services. In the process, it is our quality requirement to consistently adapt our service portfolio to our customers’ needs.
In 2017, Testo Industrial Services invested in expertise for acoustic calibrations by purchasing a free field and pressure chamber.
Highly qualified employees now calibrate instruments such as free field and pressure microphones, sound level meters, calibrators and pistonphones in our acoustics laboratory.
In the Testo Industrial Services’ free field chamber, we can calibrate acoustic measuring devices such as measuring microphones or sound level meters. Free field calibration is possible from 125 Hz to 20 kHz in third-octave or octave increments. In this process, the experts from the Testo Industrial Services acoustic laboratory work with the free field calibration system CS18FF. Calibration in the free field chamber has been specially designed for calibration of free field microphones and sound level meters in accordance with DIN EN 61094-8 and DIN EN 61672.
Scope of the calibration
Pressure microphones can be calibrated in the acoustic laboratory’s pressure chamber. In this case, Testo Industrial Services has the possibility of calibrating in a frequency range of 31.5 Hz to 16 kHz in third-octave or octave increments. We use the pressure calibration system CS18 SPL for this purpose. Calibration in the pressure chamber is suitable for calibrating pressure microphones in accordance with DIN EN 61094-5.
