Protmex PT6708 Sound Level Meter ABS Housing Fast/Slow A/C Weighting

Description

Product Overview

The Protmex PT6708 Sound Level Meter is engineered for precise acoustic measurement in a compact, handheld design. Constructed from high‑impact Acrylonitrile Butadiene Styrene (ABS), the device resists drops and daily wear while maintaining a lightweight profile of just 190 grams. Inside, a professional AD636 chip ensures low power consumption and rapid response, delivering readings within 0.5 seconds. The meter features both fast (0.125 s) and slow (1 s) response settings, allowing users to capture transient sounds or steady‑state noise levels with equal confidence. A/C weighting options let you choose between human‑ear simulation (A‑weighting) and raw sound pressure (C‑weighting), making the PT6708 versatile for a range of applications.

Usage

Designed for professionals and enthusiasts, the PT6708 excels in industrial workplaces, construction sites, schools, and home studios. Use the fast response mode to monitor sudden spikes such as machinery start‑up or alarm sounds, and switch to slow response for evaluating continuous background noise like HVAC systems or traffic. The A‑weighting mode aligns measurements with human hearing, perfect for occupational health assessments, while C‑weighting captures the true intensity of low‑frequency noise, useful for acoustic engineering and environmental studies. Its intuitive button layout and clear LCD display make on‑site measurements quick and hassle‑free.

FAQ

What is the difference between A‑weighting and C‑weighting?

A‑weighting adjusts the measurement to reflect the sensitivity of the human ear, emphasizing frequencies between 500 Hz and 6 kHz. C‑weighting records the actual sound pressure level without frequency bias, useful for low‑frequency noise assessment.

How long do the batteries last?

With the energy‑saving circuit, four AAA batteries typically provide up to 200 hours of continuous use, depending on measurement frequency and backlight usage.

Can the meter be used outdoors?

Yes, the PT6708 is rated for indoor and outdoor environments. Its robust ABS case protects against dust and light moisture, making it suitable for field measurements.

Is calibration required?

The device comes pre‑calibrated from the factory and meets IEC standards. For critical applications, periodic professional calibration is recommended.

What accessories are included?

Each package contains the sound level meter, a protective carrying case, a windscreen for outdoor use, four AAA batteries, and a quick‑start guide.
