Frequently Asked Questions

What is GASCO calibration gas used for?

GASCO calibration gas is used to calibrate portable gas detectors across all OEM brands. It verifies sensor accuracy by exposing the detector to a known concentration of carbon monoxide (140 ppm) in air, ensuring reliable readings for workplace safety compliance.

What are the specifications of GASCO 105ES-50-140?

The GASCO 105ES-50-140 calibration gas cylinder contains carbon monoxide at 140 ppm in an air background, with +/-5% accuracy and 105 L capacity. It is designed for use with all OEM gas detectors and comes as a non-refillable cylinder.

Where to buy GASCO calibration gas worldwide?
