GrayWolf’s portable and semi-permanent VOC meters, monitors are highly versatile, for low parts-per-billion ranges up to high PPM toxic VOC exposure ranges. Volatile Organic Compounds (VOCs) emanate from a broad range of sources in industrial and general indoor air quality (IAQ) applications. GrayWolf offers five different plug-and-play Photo Ionization Detector (PID) sensors to choose from; with ranges optimized for your specific application. The DirectSense II-3 probe includes your choice of any of those PIDs, along with relative humidity and temperature. Our DirectSense II-5 probe also includes the sensors for %RH, °C/°F, accommodates your choice of PID plus up to 2 specific gas sensors (electrochemical or NDIR). The DirectSense II-8 probe offers a PID, %RH, °C/°F, and the choice of NDIR carbon dioxide and/or up to 5 electrochemical specific gas sensors (8 total). Our original DirectSense I Classical probes, while not plug-and-play, are also available in various configurations. Coupled with the power of our versatile meters and monitors, end-users can efficiently log and annotate readings, while easily accessing on-board information about specific volatiles and potential sources. Optional GrayWolfLive™ software allows remote access to instrument data & notes via smartphones, IPads, Droids, PCs, etc. Meter pouches and probe belt clips allow hands-free operation. Choice of low ppb, low ppm, mid-range ppm, wide/high-range ppm and high %RH VOC optimized PID sensors Excellent sensitivity, very low limits of detection (down to <5 ppb); crucial for IAQ/green building applications
