The 114 dB sound level allows performing calibrations even in high background noise environments.<\/li>\n<li>Its simplicity of use allows the use even by unskilled personnel.<\/li>\n<li>The presence of the LCD helps you through the steps of setting the calibrator, signal the end of the span and allows you to check the status of the battery.<\/li>\n<\/ul>\n<p>ISO 17025 calibration certificate according to IEC 60942 included.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Class 1 sound level calibrator according to IEC 60942:2003.
