FAQ
Q1: What testing scenarios is this calibrator mainly applied to?
A: The sound level meter calibrator is used by acoustics professionals, occupational health and safety officers, environmental monitors and testing laboratories to verify and calibrate sound level meters, microphones and noise measurement instruments before and after measurements. It supports field calibration of sound level meters for environmental noise monitoring, occupational noise exposure assessment, industrial noise measurement and acoustics research. The calibrator produces a precise, stable reference sound pressure level at a known frequency, allowing users to verify that their measurement instrument is reading correctly and adjust if necessary. It is essential for any noise measurement program, as field calibration before and after each measurement session is required by standards such as IEC 61672 and occupational noise regulations to ensure measurement accuracy, data traceability and regulatory compliance for environmental and occupational noise assessments.
Q2: What standards does the calibrator comply with?
A: The calibrator complies with IEC 60942 for sound calibrators (Class 1 or Class 2), and relevant GB/T standards for acoustic calibration equipment. Calibration should be traceable to national standards through periodic laboratory calibration. The output sound pressure level and frequency should be verified by an accredited laboratory annually.
Q3: What is the warranty period for the whole machine and key components?
A: The whole calibrator is covered by a 12-month warranty. The electronics, transducer and housing are covered, while batteries and seals are consumables. Damage from dropping, moisture exposure or unauthorized repair is excluded. Extended service contracts are available.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation is simple: insert the microphone, activate the calibrator and verify the reading on the sound level meter. No professional training is required beyond basic familiarity with sound measurement equipment. We provide an operation manual and remote guidance. Proper microphone adapter selection and seal are important for accurate calibration.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: The calibrator itself should be calibrated by an accredited laboratory annually or per regulatory requirements to maintain traceability. Battery replacement when output level drops. Output level can be checked periodically against a reference. Routine inspection of the microphone adapter seal is recommended.
Q7: Are supporting consumables universal?
A: Batteries and microphone adapters are available from multiple suppliers, though adapter size should match the microphone diameter. Long-term consumable cost is very low.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes output sound pressure level, frequency, calibration class and adapter sizes. Additional adapters and accessories can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: No installation is required. The package includes the calibrator, adapters and instruction manual. On-site service is not included for this type of portable calibration equipment.
Q10: What types of instruments are compatible with this equipment?
A: The calibrator works with sound level meters and measurement microphones that fit the adapter size within the calibrator frequency and level range. Different microphone diameters require appropriate adapters. Users should ensure a proper seal between the microphone and calibrator, allow the calibrator to stabilize before reading, perform calibration at the measurement location temperature, and record calibration results before and after each measurement session for data traceability and regulatory compliance. The calibrator should be periodically sent to an accredited laboratory for calibration to maintain traceability.
