Portable Sound Level Meters HD 8701

The sound level meter HD 8701 is a portable instrument, easy and quick to use,
suitable for measuring industrial and civil noise levels. The noise levels can be read easily in dB(A) on the large liquid crystal display which also shows all the information concerning the mode of operation of the instrument. One second after switching on and with a resolution of 0.1 dB, the digital reading gives the continuously updated value of the RMS sound pressure level, with a type A frequency weighting. The single range from 30 to 130 dB further simplifies the use of the instrument, as the user does not have to change scale.

Portable Sound Level Meters HD 2010

HD 2010 is an integrating portable sound level meter performing either spectral
or statistical analysis. The 80 dB wide dynamic range, optionally upgradable to
110 dB, and the simultaneous measurement with different time and frequency
weightings, allow speeding up and symplifying surveys. Using an HD2010 you can analyse a sound sample programming 3 measuring parameters with the most complete freedom of choice of temporal or frequency weightings. If an undesired sound event produces an over-load indication, or simply alter the result of an integration, its contribution can be excluded using the Back-Erase function.

Portable Sound Level Meters HD 2110

HD 2110 is an integrating portable sound level meter performing either spectral
or statistical analysis. The 110 dB wide dynamic range and the simultaneous
measurement with different time and frequency weightings, allow fast and easy
surveys, even in the most diffi cult situations. Using an HD2110 you can analyse a sound sample programming 5 measuring parameters with the most complete freedom of choice of temporal or frequency weightings, either wide, octave or third octave bandwidth.

Portable Sound Level Meters HD 9101 - HD 9102

The HD9101 and HD9102 sound level generator is a battery-fed portable sound
source, suitable for calibrating sound level meters (portable and laboratory
models) and acoustic measuring stations. It’s possible to calibrate directly 1” microphones and, by means of a proper adapter (model 9101040), also 1/2” microphones; the mechanical dimensions are in accordance with standards
IEC 61094-4 (“Measurement Microphones, Part 1: Specifi cations for Laboratory
Standard Microphones”) and IEC 61094-4 (“Measurement Microphones. Part 4: Specifications for working Standard Microphones).
