The Carbon Monoxide Meter VZ7701 detects the presence of carbon monoxide (CO) and measures concentrations between 1-999 parts per million (PPM). The meter indicates the presence of carbon monoxide in two ways by a reading on the LCD in PPM and a beeper tone. The beeper function much like clicking of a Geiger counter: above 200 PPM, the beeper sounds continuously with the concentration of CO. From 25 PPM to 200 PPM the beeper sounds discontinuously with the concentration of CO. The backlight function helps to take measurements at night or in areas with low background light levels. The meter is very simple to operate.
Applications: residential and commercial building CO detectors, CO monitors for industrial applications, ventilation control for indoor parking garages, gas furnaces, room heaters, central heating furnaces, water heaters, ranges ovens, stores fireplaces...
