Industrial Scientific Ventis MX4 Calibration Gas — 4-Gas Mix & Bump Test Gas
Calibration gas and bump-test gas for the Industrial Scientific Ventis MX4 portable gas detector. Trigas USA cylinders are a direct drop-in replacement for Industrial Scientific calibration gas — same gas, same concentration, same cylinder and C-10 fitting — at 15–30% below Industrial Scientific pricing. Every cylinder is NIST-traceable with an ISO 17025 Certificate of Analysis and ships in 48 hours from our Florida facility.
The Industrial Scientific Ventis MX4 is typically calibrated with a 4-gas confined-space mix (CO, H2S, combustible/LEL, O2). Recommended Trigas USA cylinders below; pick the size that matches your regulator and cal frequency.
