Sound pressure meter

The SKF TMSP 1 is a high quality, hand-held instrument for measuring the sound level in decibels. The environmental noise is picked up by the electret condenser microphone and then processed by the handset. The surrounding noise can be monitored both quantitatively and qualitatively.

The SKF Sound pressure meter is supplied in a carrying case complete with windshield, calibration screwdriver, jack for external outputs and an alkaline battery.

User friendly and easy to operate, no special training required

dBA and dBC scale weightings for both general sound level and low frequency noise measurements suits most applications

Fast and Slow time weighting selection to enable either normal measurements or measurement of average level of fluctuating noise

Four different measurement scales to suit almost all eventualities

Wide operating temperature suitable for diverse industrial environments

User selectable backlight for use in environments with poor lighting

Four digit LCD panel with both digital and bar graph display

Max and min function for peak measurements

Alarm functions (Under/Over) to indicate when the noise level is too low or too high

Tripod mounting facility for use when the instrument must remain in the same position for a prolonged period

Conforms to IEC651 type2, ANSI S1.4 type 2 for sound level meters
