🔬 Calibration & Certification
Do your instruments come with calibration certificates?
Yes, all our sound level meters and measurement equipment include verification certificates confirming compliance with relevant standards (IEC 61672, etc.). Optional: For customers requiring formal ISO/IEC 17025 accredited calibration certificates:
- Available for selected products
- Adds some lead time to delivery (typically 2-3 weeks)
- Additional cost applies
- Provides full traceability to national standards
- Required for some regulatory applications and legal proceedings
What is ISO/IEC 17025 calibration and do I need it?
ISO/IEC 17025 is the international standard for testing and calibration laboratories. Accredited calibration means: ✅ Traceability to national/international standards ✅ Documented measurement uncertainty ✅ Recognized by regulatory authorities worldwide ✅ Accepted for legal proceedings ✅ Required for many quality management systems (ISO 9001, etc.) You need ISO/IEC 17025 calibration if:
- Your industry requires certified traceability (aerospace, automotive, pharmaceuticals)
- You're taking measurements for legal proceedings
- Your quality system mandates accredited calibration
- Regulatory authorities require documented calibration
- You need to defend measurement accuracy in disputes
- Conducting routine workplace assessments
- Internal quality control measurements
- Equipment verification (manufacturer verification is sufficient)
- Budget-constrained projects where standard verification is adequate
How often do I need to calibrate my sound level meter?
Field Calibration (Acoustic Calibrator):
- Before each use (every measurement session)
- After each use (to verify stability)
- Takes <30 seconds
- Uses 94 dB or 114 dB calibrator
- Essential for measurement validity
- Annually (recommended)
- Every 2 years (maximum interval in most jurisdictions)
- When dropped or damaged
- If field calibration shows drift >0.5 dB
What happens if I drop my sound level meter?
Even if there's no visible damage:
1. Perform field calibration immediately to check for drift
2. If calibration fails or shows >0.5 dB drift: Unit requires laboratory inspection and calibration
3. Document the incident: Important for quality records
4. Send for laboratory calibration: Don't use until verified
Prevention: Use protective carrying cases and handle carefully. Most damage occurs during transport, not use.Do you provide calibrators separately?
Yes, acoustic calibrators are available separately. When ordering a sound level meter, you'll need a calibrator that:
- Matches the microphone diameter (typically ½" or 1")
- Provides 94 dB or 114 dB reference level
- Meets Class 1 or Class 2 standard (matching your meter)
Can you calibrate instruments from other manufacturers?
Yes, we offer ISO/IEC 17025 accredited calibration services for:
- Sound level meters (Class 1 and Class 2)
- Acoustic calibrators
- Microphones and preamplifiers
- Vibration meters
- Accelerometers

🔧 Maintenance & Troubleshooting
How do I maintain my sound level meter?
Regular Maintenance: After Each Use: ✅ Wipe with soft, dry cloth ✅ Remove batteries if storing for extended period ✅ Store in protective case ✅ Keep microphone windscreen clean Weekly (for frequent users): ✅ Clean display and housing with slightly damp cloth ✅ Inspect cables and connectors ✅ Check battery condition ✅ Verify windscreen is secure Monthly: ✅ Field calibrate and verify within specification ✅ Check for firmware updates (if applicable) ✅ Inspect for any damage or wear Annually: ✅ Laboratory calibration (required) ✅ Replace batteries even if still functional ✅ Replace windscreen if worn or damaged ✅ Clean internal microphone grill (by qualified technician only) What to Avoid:
❌ Exposure to extreme temperatures
❌ High humidity or moisture
❌ Dropping or impact
❌ Covering microphone with hand during measurements
❌ Using damaged or expired calibrators
My instrument isn't calibrating correctly. What should I do?
If field calibration fails or shows drift >0.5 dB:
Immediate Steps:1. Check calibrator: Try different batteries, verify calibrator function
2. Clean microphone: Ensure no dust or debris on diaphragm
3. Retry calibration: Sometimes environmental conditions affect results
4. Try different location: Away from noise sources, wind, vibration
If problem persists:- Do not use for measurements until resolved
- Document the issue: Calibration values, error messages
- Contact us: We can troubleshoot remotely
- Send for laboratory calibration: May require service or adjustment
- Expired or failing calibrator
- Damaged microphone
- Internal electronics drift (requires recalibration)
- Extreme temperature or humidity
- Recent drop or impact
What is the expected lifespan of these instruments?
With proper care and maintenance:
Sound Level Meters: 10-15+ years- Electronics are robust and long-lasting
- Microphone may need replacement after 5-10 years
- Batteries replaced as needed
- Display and housing may show wear but remain functional
- Diaphragm degrades over time
- Accelerated by humidity, contamination, impact
- Replacement available when needed
- Very robust design
- Crystal oscillator may drift over time
- Requires annual calibration to verify accuracy
