Product Description
VOC GAS SENSOR Model C‑21 General：
The model C‑21 is a solid‑state gas monitor capable of sensing a variety of gases and vapors. The ones it is generally sensitive to are called VOCS (volatile organic compounds),and the most common application of the C‑21 is for solvent vapors. Common examples are paint thinners, dry cleaning fluids, cleaning solvents, and gasoline vapors. The instrument does not respond to carbon dioxide or radon, and has only a weak response to carbon monoxide. The C‑21 is self‑contained except for its AC adapter power module.The instrument also has an audio alarm and has outputs to external alarms, data loggers,calibration equipment, etc.
