Our prices are better than OEM’s and distributors for Crowcon Replacement Calibration Gas Standard and here’s why:

Integrity Gases, Inc. is the premier manufacturer of Crowcon replacement calibration gas standards in portable cylinders. OEM Gas Detector Manufacturers are resellers. We actually make calibration gases.


Integrity Calibration Gas Standards meet or exceed the most demanding industry specifications for Crowcon replacement calibration gases.

  1. Ideal Crowcon Replacement Calibration Gas Standards have a longer shelf life. That’s what the Ideal Cylinder patent pending process is all about. Which means you can keep a smaller inventory and save money, too.
  2. We know what you need. We are expert in both the manufacture of Crowcon replacement calibration gas standards and in the repair and maintenance of your gas detectors.
  3. Every Crowcon replacement calibration gas cylinder is individually manufactured. Standards don’t come in batches. That’s why we make them one at a time instead of bulk transfers like resellers.

Buy Direct. Get the best price.

And remember- Crowcon gas detectors and gas monitors are only as good as the Crowcon replacement calibration gas used to calibrate them.  But an incorrectly calibrated Crowcon gas detector or gas monitor isn’t worth much at all.

That’s why we offer these videos on how to calibrate your various gas detectors and gas monitors with our calibration gas.  They’re prepared by James Moore of Ideal Gases, LLC.

And anyone involved in the calibration of gas detectors should be sure to read Bulletin SHIB 05-04-2004 from the Department of Labor titled Verification Of Calibration for Direct-Reading Portable Gas Monitors.
