Description
Overview
GAOTek Filter tube gas hygrometer is one of the most advanced handheld VOC (Volatile Organic Compound) monitors available for f (parts per billion) detection. VOCs include a variety of chemicals such as for ppb benzene, alcohols, fuels, paint thinner industrial solvents and many others, which can have short and long-term adverse health effects. Measuring these compounds is essential for worker protection in industries like oil & gas, fire & hazmat, pharmaceuticals, paints & adhesives, and many others. In addition, VOC monitoring is useful chemical process control detecting leaks and other releases to the environment, and in measuring indoor air quality. The NEO offers several models from the most sensitive 1 ppb to a high range up to 15,000 ppm for different applications, and a filter tube version (NEO BENZ) for benzene specific or butadiene specific measurements. In addition to the standard continuous read-out, a Leak Detection and Repair (LDAR) mode is included. Novel designs of the Photo ionization Detector (PID) and Ultraviolet (UV) lamp provide outstanding sensitivity, stability and reproducibility. Includes real time data monitoring using Power Suite software via cable to a PC or via Bluetooth to an Android phone or tablet.
