HT Instruments HT157 Sound Level Meter
Integrating professional Class 1 sound level meter with spectrum octave band analysis
HT157 is a compact, strong and reliable Class 1 sound level meter for detection and recording of equivalent noise level, Leq, Peak value measurements, control of sound level, acoustic pollution, etc. suitable to certify environmental noise level in working areas according to national regulations in force. Thanks to a powerful microprocessor and wide measuring range from 25 to 140 dB it is possible to effect simultaneously multiple functions (statistical analysis, 24 hours, Integral Leq analysis). This model permits to perform detailed noise spectrum analysis with internal octave band and 1/3 octave band digital filters and is provided with an internal memory for saving recording results. The transfer of data to PC is carried out through USB interface by using Windows software to display numerical, graphic and statistic data. The instrument is supplied with hard carrying case a portable Class 1 calibrator for preliminary checks before starting any measurement.
