To help detect dangerous levels of VOCs indoors or outdoors, Casella CEL has introduced its new VOCpro™ battery-powered, portable VOC monitor. Using sensitive Photo-Ionization Detection (PID) technology the VOCpro rapidly detects hundreds of different types of VOCs in an extensive range of 0.1 ppm (particles per million) to 20,000 with the optional dilution probe. A 10.6eV lamp is standard, with an optional 11.7eV version available for ionizing chlorinated compounds. The UV lamp is easy to maintain and clean. A 10.6 eV lamp comes standard on the VOCpro for ionizing chlorinated compounds. Customers can also specify an optional 11.3 eV lamp.
