Formaldehyde, CH2O smart sensor The SEN-SMT-HCHO-L smart DirectSense II Formaldehyde sensor is ideal for the low (0 to 1000ppb) IAQ range, with an excellent L.O.D. (<10ppb). Unlike most EC HCHO sensors, this sensor exhibits negligible CO cross-sensitivity <10ppm CO (GrayWolf meters alert when >10ppm CO might influence readings whenever a CO sensor is also installed in the DSII probe). FORMALDEHYDE (HCHO) MEASUREMENT TO VERY LOW LEVELS OF DETECTION The FP-31G formaldehyde meter, for portable 15 or 30 minute test results, has a range from 10ppb (parts per billion) to 1000ppb, with actual limits of detection down to <5ppb (below the display value). Display your readings in ppm HCHO. These very low levels of detection are essential for Indoor Air Quality (IAQ) measurement of Formaldehyde, and are typically not achieved by alternative continuous measurement technology. Photoelectric Photometry An inserted test tablet employs the chemical reaction between formaldehyde and a chemical impregnated in the surface of the tablet. The discoloring that results from this reaction is measured via photoelectric photometry with accurate readings to <20ppb HCHO, without significant cross-sensitivity from typical background compounds, making it ideal for IAQ applications, as well as for low toxic exposure levels. APPLICATIONS Application at Schools/Colleges, Universities: Monitor/Log via Wi-Fi to the cloud with wall-mounted, desktop placed, even handheld probes. Versatile design for consistency over varied applications, taking advantage of the high-end sensor technology. Data-log for hours, days, weeks, months from GrayWolf probes set on shelves, desks, tripods or any convenient location. For portable applications, connect to 1 or multiple DirectSense II multi-sensor probes; via cable and/or via Bluetooth wireless. Application at Airports: Monitor/Log via Wi-Fi to the cloud with wall-mounted, desktop placed, even handheld probes. Versatile design for consistency over varied applications, taking advantage of the high-end sensor technology. |

FIFA WORLD CUP QATAR
During FIFA World cup in Qatar the Gray Wolf instrument kits on tripods for short or long-term trend monitoring at stadiums are pictured below. These have been used for both indoor and outdoor air measurements. Buildings of all types, including athlete housing facilities, and even land border screening areas, are also tested with these set-ups, as well as via hand-held walk-through testing and continuous monitoring connected to GrayWolfLiveTM cloud software. Parameters measured, as per FIFA, include CO2, VOCs, CO, O3, NO2, HCHO, Particulate, %RH, and Temperature.
