Main features of Hengsheng HS6022F sound level meter calibrator

The HS6022F model is a calibrator for multi frequency point sound pressure levels at frequencies of 250Hz, 500Hz, 1000Hz, and 2000Hz. Built in temperature and atmospheric pressure sensors can measure environmental temperature and atmospheric pressure in real time, and automatically correct the effects of temperature and atmospheric pressure to ensure the accuracy of the calibrator is at level 1.

2. The performance meets the requirements of level 1 of GB/T15173-2010 and IEC60942-2003 standards. Calibration of digital sound level meters and other acoustic measuring instruments suitable for 1-inch, 1/2-inch, and 1/4-inch microphones.

3. Adopting a 122 × 32 dot matrix LCD display with LED backlight to display frequency, sound pressure level, real-time temperature, and atmospheric pressure.
