WHAT WE DO
Trescal’s fully accredited acoustic calibration laboratories ensure that your audiometric, acoustic and vibration equipment performs how it was meant to. From a handheld screening device to a fully featured clinical instrument, we provide ISO/IEC 17025 accredited and traceable calibration from our laboratories or on your site.
Single Source Solutionfor high frequency, low frequency, temperature and shock accelerometer sensor calibrations.
Certified qualitythanks to our ISO 17025 accredited calibration laboratories.
Minimal downtime with our onsite services and fast turnaround time.
Single customer portalto track equipment, request repair and obtain reports.
Traceable calibrations to the international system of units (SI).
Complete certificates show the types of devices (Piezoresistive PR, Piezoelectric PE), output voltages and device masses.
Early detectionof measurement drift, corrective actions and thus improve your performance.
EQUIPMENT TYPES & CALIBRATION SCOPE
Trescal calibrates sound over all parameters such as sound level meter, intensity, power and quality as well as RT60 reverberation time and octave band analysis. We calibrate a wide range of acoustic devices, including:
- Sound level meters
- Measurement microphones
- Acoustic calibrators, pistonphones and multi-tone calibrators
- Noise dosimeters
- Outdoor and surface microphones
- Sound intensity probes
- Free-field calibration: 125 Hz…20 kHz (sound pressure level 75 dB to 94 dB)
- Pressure calibration (in an electroacoustic coupler): 31.5 Hz to 16 kHz (64 dB to 114 dB)
- Pressure calibration (two-point with pistonphone and calibrator): 250 Hz (94 dB, 114 dB or 124 dB) and 1 kHz (94 dB or 114 dB)
- Pressure chamber, low frequency (only factory calibration possible): 0.1 Hz to 31.5 Hz (124 dB)
- Full electrical calibration
