The MH-75 from TURBO FOG Division of Kingscote Chemicals is a self-contained smoke tester for easily identifying leaks, infiltration and cross connections in municipal collection lines. The smoke-testing system uses leak-proof liquid aerosol smoke cartridges to create dense white smoke. No additional smoke bombs or garden sprayers are required. Made of 11-gauge powder-coated steel, the blower is capable of generating over 7,500 cfm to accurately test more pipe in less time. Briggs & Stratton and Honda engine models are available. 800/394-0678; www.turbo-fog.com.
