Gas Detection Calibration
NIST-traceable calibration and bump testing for gas detectors, gas monitors, gas sniffers, and gas analyzers. Protecting workers with accurate gas detection for workplace safety and regulatory compliance.
Why Gas Detection Calibration Matters
Gas detection calibration is critical for workplace safety in environments with toxic, combustible, or oxygen-deficient atmospheres. Accurate gas detection prevents accidents, saves lives, and ensures OSHA compliance. Regular calibration and bump testing verify that your gas detectors respond accurately to hazardous gases including H₂S, CO, CH₄, O₂, and other toxic or combustible gases. Without proper calibration, gas detectors can fail to alarm, creating life-threatening situations for workers.

Our Calibration Process
Multi-gas calibration and bump testing with NIST-traceable standards
Receiving & Inspection
Each gas detector is logged into our system with unique identification. Visual inspection documents condition, sensor types, battery status, and calibration history.
Bump Test
We perform a bump test (functional test) to verify the detector responds to known concentrations of target gases and that alarms activate properly.
Zero Calibration
Detectors are zeroed in fresh air or zero gas to establish the baseline reading. This ensures accurate measurement of gas concentrations.
Span Gas Calibration
Known concentrations of NIST-traceable calibration gases are applied to each sensor. The detector is adjusted to read accurately at the span gas concentration.
Verification & Testing
After calibration, we verify accuracy with additional test gases and confirm alarm setpoints activate at proper concentrations. Battery and sensor condition are documented.
Certification & Return
Complete calibration certificates include bump test results, as-found/as-left data, gas types and concentrations used, sensor life remaining, and traceability documentation.
