HT155 is mobile integrating sound level meters Type (Class 1) which can be used to monitor the equivalent level of nose (Leq), measure Peak values, check soundproofing levels, acoustic pollution, etc.

 

Ii is also indicated for certification according to the Leg. Decrees currently in force as regards environmental noise measurements and in working environments. These devices have a wide measuring range (from 25 to 140dB) and multiple functions such as statistic analysis, 24H analysis, integration of Leq over time, which are indispensable elements when measuring.

 

These models also allows carrying out detailed analyses of spectrum components of noise using integrated octave-band filters and 1/3 octave-band filters (only HT157) and they are provided with an internal memory to save data and with a USB interface for transferring data to the PC through dedicated software in a Windows environment with possibility of numerical, graphic and statistic display. Sound level meters ape provided with a practical and resistant case with a mobile calibrator for preliminary checks before each measurement is carried out.
