Sensor Electronics' Ketone Kops offers protection from dangerous concentrations of VOC solvents, such as methyl amyl ketone, methyl ethyl ketone and the like, by measuring their concentrations in the air. The tool continually monitors gas levels in the protected area, flashing an alarm the instant concentrations reach a danger point. Comes with a dedicated transmitter to show actual gas levels on a digital readout panel. Color-coded LED's glow green/amber/red to reflect changing gas concentrations. At red the transmitter can turn on alarm lights and sirens, even fans to flood the area with outside air.
