For 20 years GrayWolf has offered advanced, highly versatile portable and semi-permanent multi-gas toxic gas, such as Ozone (O3), Ammonia (NH3), Chlorine (Cl2), H2S, SO2, NO2, HCl, HCN, H2, CO2, ClO2 meters, monitors, and more. Our all-new DirectSense® II and classical DirectSense I multi-gas probes, when connected to our purpose-built AdvancedSense® meters, to tablet PCs, to WolfPack® area monitors, or to the cloud via WiFi combine the latest available electrochemical, PID and NDIR gas sensor technology with the advanced capability of mobile computing. GrayWolf toxic gas monitors harness the power of our rugged, embedded computer meters and economical mobile PCs to significantly improve your toxic gas test and reporting capability

SO2 NO2 NO CO NH3 H2S
CO2 HCN HCl H2 O2 O3 EtO Cl2 SiH4 F2

AsH3 B2H4 PH3 ClO2 COCl2 HF Sensors

Select from one up to 6 gas sensors, plus temperature and %RH, in a single probe, from a choice of 25 different gasses.
In addition, options for Formaldehyde, Airflow, Differential Pressure, Particulate, and more interconnecting sensors/meters.
DirectSense II probe smart sensors are plug-and-play, change them out yourself for the application at-hand, when you want to add measurement parameters in the future, or just to send individual sensors in for updated “Factory” calibrations.
Plug in multiple probes (2, 3, even 4) simultaneously into a single meter.
