The Mil-Ram Sample Draw Gas Detection System can be used for areas that are too hot, too cold or inaccessible. The Sample Drawing Module can be used with any Mil-Ram “smarter Transmitter” to continuously extract sample from remote locations. Explosion-proof or NEMA 4x plastic enclosures available. Transmitters feature self-calibration, labor-free auto self-calibration adjusts span monthly based on life curve, auto calibration (auto gas calibration in 2 minutes), non-intrusive hands-free, off-site sensor calibration to replace sensors in the field without recalibration, and more.Mil-Ram Technology, Inc.,, (888) 464-5726.
