World Cup Qatar

The FIFA World Cup is about to open and fans, players and staff will have had many venues tested and/or have on-going monitoring with GrayWolf’s top-end IAQ instruments. GrayWolf 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. Check out this brief FIFA article on air pollution control for the tournament: https://publications.fifa.com/en/sustainability-report/environmental-pillar/air-quality/air-pollution-control-during-tournament-time/

NEW: Smart IAQ Range Formaldehyde Sensor for DirectSense® II Probes

10ppb – 1.0 ppm range


Real-time, fast response Formaldehyde readings with this smart, plug & play sensor. Inserts into DirectSense II probes* along with temperature and %RH, plus up to 5 additional smart sensors in one DSII probe. (Note: a CO sensor is recommended so that CO levels exceeding 10ppm will trigger a warning of potential influence on HCHO readings).

*Requires probes manufactured June 2021 or later

FP-31G Compact Formaldehyde Meter

GrayWolf brands this portable HCHO meter, also with exceptional low limits of detection (LODs).
Toxic Gas Brochure

The FP-31G meter may be used from 10ppb to 1.0ppm and is ideal for IAQ applications (30-minute test) or low toxic exposures (15-minute test).

While this low-range formaldehyde detection meter does not continuously monitor or directly output to GrayWolf platforms, readings can be manually entered into WolfSense® log files, at the time that they are taken, supplemental to a host of other GrayWolf continuous IAQ or toxic exposure parameters. GrayWolf has years of experience offering this meter, with proven performance, allowing us to now add our name (and the extra support that goes with that) to the product.
