The Triplett FM260 Formaldehyde and TVOC Meter can simultaneously display real-time measurements of HCHO/CH2O (Formaldehyde) and TVOC (Total Volatile Organic Compounds) concentrations in the air. Potential sources for TVOCs include paints, finishes, adhesives, cigarette smoke, pesticides, personal care products, car exhaust, new furnishings, wall coverings, household cleansers, and cooking fuels. Chemicals include: Acetone, Ethylene Glycol, Formaldehyde, Xylene, 1,3‐butadiene, Tetrachloroethene, Hydrogen Sulfide, Ammonia, Toluene, Benzene, Methylene Chloride, Perchloroethylene, and MTBE. The meter features Fuel Cell Formaldehyde Sensor Technology for high accuracy measurement, a backlit dual LCD, two selectable units of measure (ppm, mg/m³), audible and visual high/low alarms for HCHO. Auto power off conserves battery life. Includes rechargeable 7.4V Li-Po battery and AC charger/adapter..
