Amprobe Sound Level Meter 35 dB to 130 dB LCD Display IEC 651 Type 2 ANSI S1.4 Type 2 SM-10

Amprobe SM-10 Sound Level Meter is a professional handheld instrument for measuring environmental and workplace noise levels, offering a range from 35 dB minimum up to 130 dB maximum with high precision. It utilizes IEC 651 Type 2 and ANSI S1.4 Type 2 accuracy standards, suitable for safety, health, and quality control professionals needing reliable sound pressure readings.

Featuring a user-friendly LCD display with 0.1 dB resolution, the meter supports selectable frequency weighting filters (A and C) to adapt to different acoustic scenarios. The device covers a frequency range from 31.5 Hz to 8 kHz, providing comprehensive acoustic measurement capability.

The SM-10 runs on a standard 9V alkaline battery with approximately 50 hours of operation, making it ideal for extended field work. It supports FAST (125 ms) and SLOW (1 s) responses to capture transient and averaged noise levels accurately. The meter operates effectively within ambient temperatures of 5°C to 40°C with relative humidity under 80% RH.

This sound level meter is suitable for applications such as workplace noise surveys for safety engineers, hearing protection assessment by industrial hygiene teams, quality control of machinery noise, acoustic material testing requiring C weighting, and occupational sound limit compliance monitoring.

The device features a low battery indicator on the LCD for timely battery replacement and recommends an annual recalibration cycle to maintain accuracy. It comes supplied with a soft carrying case, windscreen, user manual, and a 9V battery to support field use.

IEC 651 Type 2 and ANSI S1.4 Type 2 accuracy for standardized noise measurements. Range of 35 dB to 130 dB sound pressure level measurement. Frequency weighting filters (A and C) for versatile acoustic evaluation. 0.1 dB resolution on a four-digit LCD display.
