Enhanced, Market Leading CO2 Sensor Specifications

GrayWolf’s custom manufactured Carbon Dioxide sensor, together with our new smart sensor electronics, improved software linearization/compensation and upgraded factory calibration methods have enabled GrayWolf to further improve our excellent CO2 accuracy specification. +/- 35ppm (with no additional %rdg offset) over the IAQ range (350ppm-2000ppm). This is particularly important for IAQ and ventilation (ACH calculation via CO2 tracer gas) applications. Yet, the same sensor also has the versatility to be utilized reliably for 8-hour TWA toxic CO2 exposures, with excellent specs to 10,000ppm and a usable range to 20,000ppm. Contact us for details.   

Free VentCalExtended until Year-End

In response to COVID-19, Air Changes per Hour (ACH) is proving to be a key parameter to test and adjust ventilation systems, as needed, to assure dilution air recommendations in school rooms, offices, retail spaces, residences, airports, bathrooms; just about any indoor space where occupants are subject to Coronavirus exposure. A free copy of our VentCal software, which helps calculate and report on ACH, is available with any GrayWolf kit purchased by December 31st, 2020 that includes a CO2 sensor.
