RKI Calibration Gas Cylinders Configuration:NO2 10 ppm / CO 50 ppm / O2 12% / CH4 2.5% in N2, 58AL at one or two pointsRKI calibration gas cylinders provide certified reference concentrations for bump testing and calibrating RKI portable and fixed gas detectors. Available in single gas and multi gas mixtures across steel and aluminum cylinders in several sizes, each cylinder is factory certified to a specific concentration and expiration date. The configurations listed here cover the most commonly ordered single gases (methane, hydrogen, propane, hexane, isobutane,
