NIST traceable calibration is an assurance program that certifies a laboratory’s equipment is calibrated.
NIST traceable gas meter calibration
NIST traceable gas meter calibration from CIH Equipment provides the technical certainty you need for high-stakes safety programs. We maintain an unbroken chain of calibrations that connects your portable or fixed gas monitors directly to the National Institute of Standards and Technology. This service protects your site from audit failures and inaccurate field readings that put lives at risk.
NIST traceable gas meter calibration is the core of a reliable industrial hygiene program. Our laboratory in Clearwater, Florida, serves industrial sites across the country.
CIH Equipment understands that a documented unbroken chain of data is the only way to prove compliance during a surprise inspection.

When you send your instruments to us, we don’t just check for a response. We verify measurement accuracy using a primary standard. This standard is part of the NIST traceability chain, meaning every measurement we make is linked back to the National Institute of Standards. This link is vital for legal and safety reasons.
Our process involves more than just a simple test. We use high-purity gas calibration mixtures to verify that your sensors respond correctly to specific concentrations. Whether you need multi-gas meter certification or single-gas sensor repair, we provide a clear paper trail. This documentation shows that your testing equipment was verified against a known, high-level Measurement Standard.
Bumped vs. Calibrated: Knowing the Difference
Many safety programs rely on a daily bump test. A bump test verifies the sensor reacts to gas, but it does not verify accuracy. NIST traceable gas meter calibration is a more rigorous process. We adjust the instrument so its readings match the known value of the calibration gas.
This level of service prevents the sensor drift that often happens in harsh industrial environments. If your monitors are exposed to high humidity or extreme dust, their accuracy will change over time.
Our technicians perform flow cleaning and check the internal flow meter to verify the device operates within the manufacturer’s tolerance.

CIH Equipment is an ISO 17025:2017 accredited laboratory. This accreditation means we follow strict rules for technical competence and quality management. We use a wide range of specialized tools, including mass flow controllers, to manage gas delivery during the calibration process.
Our accredited calibration service includes calculating the uncertainty for each measurement. This is a requirement for ISO 17025:2017 and is a key part of the NAPT traceable quality program. When you receive your traceable calibration certificate, you see the exact data needed to pass any regulatory review.

The “Paper Trail” is what saves you during an audit. Each i standard we use is documented. We provide certificates that list the unbroken chain of calibrations. This includes the serial numbers of our standards and the date they were last verified by the National Institute of Standards and Technology.
Our asset management system helps you stay ahead of schedule. We track your calibration dates so you never have an expired instrument in the field. This reduces equipment downtime and helps you manage your safety budget more effectively.

It means the calibration of the meter can be traced back to the National Institute of Standards through a documented unbroken chain of comparisons. Each step in the chain has a known level of uncertainty. This provides a high level of confidence in the measurement accuracy of your device.
Most manufacturers recommend a full gas calibration every six months. However, if your equipment is used in dirty or high-risk areas, you should consider more frequent service. Regular calibration helps identify sensor drift before it becomes a safety hazard.
No. A bump test is a quick check to see if the sensors and alarms work. A traceable calibration is a full adjustment of the instrument to a known standard. You need both to maintain a safe work environment and meet legal requirements.
Yes. We offer onsite service for facilities with a large number of instruments. This is common at refineries and large manufacturing plants where shipping equipment would cause too much delay. Our team brings the primary standard and gases directly to your location.
Your certificate includes the “as found” and “as left” data, the NIST traceability chain information, and a statement of compliance. It also lists the Measurement Standard used and any adjustments made to the device.
