Short answer: A dedicated sound meter may be easier to manage as a shared workshop instrument, but a product page alone does not prove that it is more accurate than a free phone app. Electroniclevel lists the CENTER-32 English-version meter at £165.99, with IEC 61672-1 Class 2 wording in the title and a preliminary-reading use case. The page does not publish accuracy, range, settings, calibration, logging or a comparison with apps. Choose based on the record and decision required: a rough comparison, a worker-exposure assessment, a property complaint or a formal report each needs different evidence.
Key takeaways
- A dedicated meter is not automatically proven more accurate than an app.
- The CENTER-32 listing supports preliminary readings but omits comparison and calibration evidence.
- Define the required record before spending money on an instrument.
Compare the job, not the gadget
A phone app may help someone notice a change, while a dedicated instrument may be easier to assign, store and use consistently. Neither option answers the buying question until the user defines whether the result is only a preliminary comparison or must support a formal workplace or property decision.
| Use case | Evidence question |
|---|---|
| Rough before-and-after check | Can the same person repeat the same observation? |
| Shared workshop record | Can identity, settings and context be documented? |
| Worker exposure | Is a representative competent assessment required? |
| Formal complaint or report | What method and supporting documents will be accepted? |
Run a fair preliminary comparison
HSE says workplace noise information should represent the work and its variation. That principle applies when comparing tools: keep the source, position, task and timing as similar as practical, and write down what changed.
- Choose one machine, location and operating condition.
- Record date, time, duration, position and surrounding activity.
- Repeat the observation with the app and the dedicated meter without changing the task.
- Label the results as preliminary and avoid claiming an accuracy winner without evidence.
What the CENTER-32 offer does not prove
The current page does not publish accuracy, range, weighting, time response, calibration, logging, microphone details or an app comparison. The manufacturer does not specify those fields in the supplied material. The Class 2 wording is in the title, but no separate supporting document is displayed.
Know when an app comparison must stop
HSE's noise-risk guidance says assessment is more than taking measurements and should lead to controls where needed. If the decision concerns worker exposure or a formal report, do not use a simple app-versus-meter test as the final answer. Seek the competent method and evidence required for that purpose.
