California industrial safety managers and environmental consultants rely on precision data to meet strict noise ordinances and Cal/OSHA requirements. Sound Level Meter Calibration in California ensures your hardware provides accurate readings during critical field surveys.
Whether you operate out of the Silicon Valley tech corridor or the heavy industrial zones of the Inland Empire, CIH Equipment delivers NIST-traceable results that withstand regulatory scrutiny.
Following the closure of Odin Metrology, CIH Equipment provides California with reliable, high-precision sound level meter calibration services.
We deliver the technical expertise and quality standards you previously expected from Odin, supported by our advanced acoustics lab and fast turnaround times.

Sound Level Meter Calibration is a technical necessity for teams monitoring workplace exposure or environmental impact. Equipment like a calibrated decibel meter or calibrated noise meter can experience drift over time due to humidity, temperature changes, or microphone diaphragm degradation.
Our lab specializes in verifying the accuracy of your sound level meters and noise dosimeters to ensure your data remains defensible.
We support a wide calibration scope that includes high-end instrumentation used in California’s aerospace, construction, and manufacturing sectors. Our technicians provide the exactness your project demands.

Maintaining compliance is about more than just a sticker on the side of your device. Every sound level calibrator processed through our facility undergoes rigorous testing against international standards such as ANSI S1.4 and IEC 61672.
We understand that an audit failure in a highly regulated state like California can stall a project for weeks.
CIH Equipment operates under the strict guidelines of ISO/IEC 17025:2017. This accreditation signifies that our lab meets international requirements for technical competence and produces valid results.
When you send in your sound meter calibration work, you receive documentation that proves your equipment stays within specified tolerance levels.
Rigorous Laboratory Testing Protocol
Our technicians do not just perform a basic function check. We test the physics behind the measurement. During the service for your sound level meters, we verify:
- Sound Pressure Level: We confirm the unit reads the correct decibel level at reference points, such as 114 dB at 1 kHz.
- Frequency Response: We verify how the microphone handles various tones across the spectrum.
- Linearity: We check that the meter tracks changes perfectly as volume increases from quiet to loud.
- Time Weighting: We confirm "Fast" and "Slow" response settings react at the correct speed.

Our calibration services extend to specialized hardware used by industrial hygienists across the West Coast. We provide Casella CEL-120/2 service and support for other leading brands to keep your fleet operational. Beyond acoustics, we handle flow meters and air sampling equipment, allowing you to centralize your equipment management.
California’s diverse industries, from the refineries in Richmond to the logistics hubs in San Bernardino, require fast turnarounds to minimize equipment downtime. Accurate sound meter calibration prevents the risk of over-protecting or under-protecting workers based on faulty decibel data.

Noise-induced hearing loss remains a top workers’ compensation concern. Using a calibrated decibel meter is the only way to confirm your engineering controls are working. If your calibrated noise meter is off by even 2 dB, you might miss a hazard or waste money on unnecessary mitigation.
- Avoid Regulatory Fines: Cal/OSHA and local agencies require documented proof of equipment accuracy.
- Reduce Liability: Defend your data in legal or insurance proceedings with ISO/IEC 17025:2017 accredited certificates.
- Maintain Data Integrity: Eliminate "drift" as a variable in your long-term environmental studies.

How often should I schedule sound level meter calibration in California?
Most standards and manufacturers recommend annual service. However, if you use the meter in harsh environments with high dust or humidity, such as agricultural sites in the Central Valley, you might need service every six months.
What is the difference between Class 1 and Class 2 meters?
Class 1 meters are precision-grade instruments used for laboratory or enforcement work with tighter tolerance limits. Class 2 meters are general-grade instruments used for basic noise surveys.
Do I need to send my field calibrator too?
Yes. You should calibrate your sound level calibrator (the device used for daily field checks) annually. If your field check device is inaccurate, your daily verifications are invalid.
Can you handle a wide calibration scope for different brands?
CIH Equipment services a broad range of brands. We specialize in acoustics and airflow, providing a one-stop solution for industrial hygiene professionals.
Is your lab accredited to ISO/IEC 17025:2017?
Yes. We maintain accreditation to ISO/IEC 17025:2017 to meet the highest quality standards for laboratory testing and calibration.
