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, Tango^Plus 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 Tango^Plus 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).

Typical application of Tango ^Plus:

• Traffic and industrial noise measurements
• Neighborhood and recreation noise monitoring
• Workplace noise measurements
• Monitoring / logging of traffic noise
• Occupational noise measurements
• Frequency analysis in 1/1 or 1/3octaves in real-time.

Modern technology combines utmost accuracy with simplest operation

The accuracy of the measurement may be considerably improved by calibrating the sound level meter before each measurement. This calibration also remains intact after switching off the device. Because of its reasonable price, easy operation and small dimensions, Tango^Plus is the ideal instrument for all users whose measurement tasks require a Class 1 measuring device according to the IEC 61672 standard.

A comprehensive memory management scheme allows different storage cycles to be selected for the various measurement values. In order to prevent incorrect settings from being selected by inexperienced users, the Setup function can be disabled via the interface (Easy Operator Mode).

Type approval by the PTB (legal calibratability in Germany) has been applied for.

Frequency analyser in 1/1 and 1/3 octaves

The Tango ^Plus sound level meter includes a real-time frequency analyser function with 1/1 and 1/3 octaves according to IEC 61260 class 1 as standard.

Workplace protection applications

For labor protection applications, in addition to the Cweighted values, the exceedance times for three freely-selectable LCPeak thresholds can be measured. This non-standard measurement values allows the degree of noise exposure at a workplace to be captured much better than a measurement of the peak value alone.

Environmental protection applications

Tango ^Plus allows three freely-selectable statistical values to be measured and saved. These L_AFN% percentiles express what A-weighted level was exceeded in N% of the measurement time.

Highest ease of use via integrated software package TANGO-Utilities for Window

The Tango^Plus sound level meter may also be operated via USB interface. In this case the PC powers the device through the interface (the scope of delivery also includes a USB adapter for mains power supply). The included Tango-Utilities software allows the operation and configuration of the instrument via PC as well as the data transfer between the two devices.

A separate window is displayed on the PC which allows easy setting of the parameters and rapid transfer of the stored measurement values. A unique feature of Tango is that several measurement values can be stored with individual sample times. The file names and sizes of the saved measurement values are displayed for transfer or deletion. The USB interface also enables the user to integrate Tango^Plus easily into a PC-based measuring system.

Tango-Utilities (included in the delivery)
Combined with a USB interface the Tango-Utilities software provides the ability to retrieve and store the measurement data stored on the instrument and convert them to an Office standard format. Furthermore you are able to create an individual set-up for Tango and transfer it to the instrument (measurement values, storage cycles, percentiles).

AUDITOR_light
The combination of the Tango sound level meter and the AUDITOR_light post-processing software forms a powerful Solution for the measurement, evaluation and documentation of time-varying environmental noise. The post-processing allows effective calculation of the rating level according to TA-Lärm and international standards and directives. With the full version of AUDITOR you are able to process the measured values of any SINUS Messtechnik GmbH sound level meter or analyzer, including Tango.
