PT6708 Digital Sound Level Meter 30-130 dB - Fast/Slow Response

Our review of the PT6708 digital sound level meter finds it best suited for technicians, audio hobbyists, and facility managers who need a compact, accurate decibel reader for routine checks and troubleshooting. The single biggest reason to buy is its combination of a high-quality AD636 chip and condenser microphone, which delivers quick readings (response within 0.5s) across a 30 to 130 dB range with +/-1.5 dB accuracy; that responsiveness makes brief spot checks and changes in environment easy to capture without elaborate setup.

Key Features

• Fast response: The meter reports changes in sound within 0.5s so users can see transient noise spikes quickly.
• Wide measurement range: Covers 30 to 130 dB so it is useful for quiet indoor environments up to loud machinery or traffic noise.
• Fast/Slow selectable: Choose a 0.125s fast or 1s slow time constant for readings tailored to either fluctuating or steady sound fields.
• A/C weighting options: A-weighting simulates human hearing for ambient checks while C-weighting captures actual sound pressure for machinery analysis.
• Useful functions: MAX, data hold, under/over indication, and dB/SONE selection make recording and comparing levels straightforward.
• Energy-saving design: Composite housing with anti-slip build and auto backlight-off extends battery life for field use.

Who It's For

The PT6708 is aimed at technicians, product engineers, school or facility maintenance staff, and audio hobbyists who need a portable, reliable meter for noise surveys, basic product QC, or on-the-fly checks of speakers and machinery. Its quick response and selectable weighting make it flexible for work and life environments like workshops, classrooms, and road noise assessments.

Those who need formal, certificated reporting or continuous logged datasets should look elsewhere or pair this meter with separate logging tools, since the device does not generate full reports or store extended logged sessions by itself.

Pros & Cons

Pros

• Accurate measurements with an AD636 chip and condenser microphone for reliable spot checks.
• Fast and slow response modes plus A/C weighting provide measurement versatility across tasks.
• Compact, anti-slip housing and auto backlight-off that help with handheld or nighttime use while conserving batteries.
• Includes practical functions like MAX and data hold for quick comparisons.

Cons

• Cannot create or export formal reports directly from the device, so follow-up documentation requires manual transfer.
• No built-in long-term logging or advanced connectivity for automated datasets.

Frequently Asked Questions

Does the PT6708 record data long term?
The meter offers MAX and data hold but does not provide long-term internal logging or report generation; export must be manual or done via separate equipment.

Which weighting should I use for ambient noise?
Use A-weighting for ambient noise because it approximates human hearing; use C-weighting when measuring actual sound pressure of machines.

Are batteries included and is there power saving?
Yes, batteries are included and the device has an auto backlight-off feature to conserve power during field use.
