Gas Detector Calibration Services

Gaseous environments are ubiquitous in industry and confined spaces, necessitating gas detector calibration services and repairs. Confined work spaces are found in chemical plants, underground mines, power generation, oil refineries, and agricultural plants and much throughout industry and commerce.  The air may be contaminated with carbon monoxide, methane, hydrogen sulfide, explosive gases, oxygen deprivation, arsine, phosphine, hydrogen cyanide, and an entire host of other bad players. 

OSHA regulates the workspace and confined spaces.  It is imperative that when these space are evaluated, that the gas detectors are up to snuff.  They need to provide accurate measurement data, be sensitive, be specific, be durable, and be loud.  The alarm must be loud enough to alert entrants and supervisors.  Gas detectors and measurement systems can mean the difference between life and death.

At CIH Equipment, we take great care to ensure that your gas monitor has the proper stated air flow, has good working sensors, that the batteries are healthy, and that the entire unit is up to original specifications. Not only must a bump check be done just prior to entry into a confined space, the unit must be able to survive the trip.  Aging sensors, a crippled pump, or short life batteries can leave you in the lurch and stop the project or worse.

Why calibrate your gas detector?

  • Full gas detector calibration services and repairs go a step farther than a functional bump test and ensures maximum accuracy of the instrument if performed successfully. Using a known comparison of test gas, the gas detector reading is compared to the actual concentration of the gas and then adjustments are made to the readings if they do not match. 
  • If a sensor fails calibration, it should be replaced and the instrument must be re-calibrated.
  • Recently, OSHA published a bulletin specifically addressing the need for regular calibration of direct reading gas detectors. Although it is not a standard or regulation, the bulletin is a clear recommendation to follow guidelines put forth in the position statement released by the International Safety Equipment Association (ISEA) on instrument calibration for gas detectors used in confined spaces.

Gas Detectors

A gas meter is a specialized flow meter, used to measure the volume of fuel gases such as natural gas and liquefied petroleum gas. Gas meters are used at residential, commercial, and industrial buildings that consume fuel gas supplied by a gas utility.

Gas Detector Calibration

An annual NIST-traceable calibration by CIH ISO accredited facility provides assurance that your device is working properly and your readings are defendable. Our calibrations are recognized as primary gas flow standards for highly-accurate flow measurement.
