Tango Plus


OVERVIEW
TANGO PLUS FEATURES
Tango Plus - sound level meter for all measurements necessary in workplace and environmental protection The Tango Plus sound level meter according to IEC 61672 with 1/1 and 1/3 octave analyser for workplace and environmental protection applications. Due to its intelligent software concept and its measuring range of 110 dB without switching to another range, TangoPlus is still very easy to operate despite its high functionality.
 
It is possible to use the detachable microphone & preamplifier via extension cable. An outdoor protection kit is available on request. The measured values are shown on a TFT colour display and are readable even over larger distances in sunlight or in darkness. The clearly arranged keyboard has a perceptible keystroke. Tango Plus has, based on state-of-the-art circuit technology, a very low power consumption. Two batteries (1.2 ... 1.5 V, size AA) guarantee an operation time of 40 h and a storage time of 10 years (for lithium batteries). Therefore TangoPlus is practically always ready for use. The instrument has a real-time frequency analyser function for 1/1 or 1/3 octave values.
 
The Tango Plus sound level meter allows for simultaneous A and C-frequency weightings as well as Fast, Slow and Impulse time weightings. In addition to the momentary sound level values, the instument allows the maximum and minimum sound level values over a given period to be measured. Tango can also measure the LAeq, LCeq, LAtm5 and LAtm5-LAeq values. The instrument has a real-time frequency analyser function for 1/1 or 1/3 octave values.
 
All measurement values chosen in the Setup are computed simultaneously and one of these values is selected for display. After starting the integrating measurement, all values are saved automatically. With the help of the USB interface and the Tango-Utilities software, the measured values can be read from the memory, saved and converted to a standard office format. Additionally, the software allows a user-defined setup to be defined and transferred to the device (measured values, storage cycles, percentiles).
