General Noise Meter / Model Number M1552TP-1090K
The M1552TP-1090K is an integrative type general sound level meter that complies with the Measurement Act and is capable of measuring environmental noise, traffic noise, construction noise, and work noise.
■Measurement Performance ●It can simultaneously measure equivalent noise level (Leq), single event noise exposure level (LE), time-weighted noise level (Lx), maximum value (Lmax), and minimum value (Lmin). ●Each calculation result can be read and confirmed with button operations. ■Screen Display ●Displays a wide range of 90dB on a large, easy-to-read LCD. ●In addition to the digital display of instantaneous values, it can also display a bar graph, allowing for a more intuitive understanding of sound movement. ■Other Functions ●Standard features include DC output and AC output on the side of the main unit. ●DC and AC signals can be extracted simultaneously.
