Designed for use in boiler rooms and car
parks, the new MX 15 controller provides
the most cost effective solution for the
monitoring toxic or flammable gases and
vapors in ambient air.
Easy to install and operate, the MX 15
control unit combined with the OLC(T) 10
detectors provide a low cost solution for
light industrial applications.
