รายละเอียดสินค้า :
• HD 2020 sound level calibrator
• portable, battery operated sound source
• suitable for sound level meters (portable and laboratory)
• class 1 according to IEC60942:2003 with LCD display.
• ISO 9001 calibration report included.
• 1000Hz frequency allows calibrating sound level meters with any weighting

• 1000Hz frequency allows calibrating sound level meters with any weighting
รายละเอียดสินค้า :
• The 1000 Hz frequency allows calibrating sound level meters with any frequency weighting (LIN, A, B, ...), without applying any correction factor.
• The generated sound pressure level is indipendent of atmospheric pressure: you don’t need to adjust the value according to static pressure over a wide range of values.
• The calibrator can be conveniently used both in laboratory and in the field. The 114 dB sound level allows performing calibrations even in high background noise environments.
• Its simplicity of use allows even unskilled staff to use it.
