ST-106 : Class 1 Integrated Sound Level Meter Comply with IEC-61672-2002 Class 1
ST-106, Integrating sound level meter, is a highly accurate instrument that measures numerous variables at the user’s discretion. It take simultaneous readings for A/C/Z and for F/S/I, thereby helping to locate noise sources whilst measuring ambient noise levels.
Despite the enormous range of adjustable settings, the ST-106 Class1 Integrating Sound Level Meter is surprisingly easy to use because its large dynamic range (>110dB) means that the measurement range need not be set before use. Furthermore, the backlit LCD display is clear and simple to read. The ST-106 can display information in both number and graph form in real time and also possesses a real time clock and calendar for further practicality.
