GrayWolf’s portable, semi-permanent, and continuous VOC meters, monitors, instruments 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 air quality and commercial, institutional, and residential indoor air quality (IAQ) applications. GrayWolf offers 4 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 sensors. Our DirectSense II-5 probe also includes the sensors for %RH, °C/°F, and 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 (exceptionally accurate carbon dioxide CO2) and/or up to 5 electrochemical specific gas sensors (8 total). 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. 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 %RH and °C/°F are also included; add up to 5 specific gas sensors, in addition to the PID, in one probe Choose from 25 different electrochemical gas sensors, such as carbon monoxide (CO), ozone (O3), ammonia (NH3), Cl2, H2S, NO2, NO, SO2, ClO2, HCN and more
