Integrating basic sound level meter PTB model registration 21.21 / 12.04 OVERVIEW The Tango sound level meter is a compact, PTB-approved, basic Class 1 sound level meter for occupational and environmental safety applications. With an intelligent software design and a measuring range of 110dB, which does not require range switching, Tango is very easy to operate despite its many functions. Tango enables even inexperienced users to measure and evaluate sound levels without errors immediately. Tango's permanently polarized, removable 1/2" microphone is automatically calibrated with a standard acoustic calibrator. A backlit, high-contrast display indicates the measured values and offers good readability in sunshine or darkness, even over larger distances. The keypad is arranged clearly and offers perceptible keystrokes. State-of-the-art circuit technology provides Tango with an ultra-low current consumption. The two batteries (1.2 ... 1.5V, AA type) safeguard operating times of up to 120h and storage over 10 years (with Lithium batteries). This makes Tango virtually always ready to use. The Tango sound level meter simultaneously works with the frequency weightings A and C and the time weightings Fast (125ms) and Slow (1s). Apart from the instantaneous sound levels LAF and LAS as well as the maximum levels LAFmax, LASmax and LCpeak in one time domain Tango also measures LAeq, LAE, LAtm5 and LAtm5-LAeq integrated over a given period. Additionally exceedance periods for three user-selectable LCPeak thresholds may be determined. The set-up enables the user to define which of these values shall be determined or stored.
