Toxic Multi-Gas Meters, Monitors

For handheld & long-term Toxic Gas measurement and logging

For 25+ years GrayWolf has offered advanced, highly versatile portable, semi-permanent, and continuous monitoring multi-gas toxic gas instrumentation for parameters such as Ozone (O3), Ammonia (NH3), Chlorine (Cl2), Hydrogen Sulfide (H2S), SO2, NO2, HCl, HCN, H2, CO2, ClO2 meters, monitors, and more. Click here to see the full sensor table. Our new DirectSense® XM probe-dataloggers can store months of data onboard or be connected to our purpose-built AdvancedSense® meters, to tablet PCs, to WolfPack® area monitors, to Android or iOS devices, or to our cloud GrayWolfLive™ application via Wi-Fi, combining the latest available electrochemical, PID and NDIR gas sensor technology with the advanced capability of mobile computing. GrayWolf’s toxic gas monitors harness the power of our range of high feature platforms to significantly improve your toxic gas test and reporting capability.

DirectSense XM TOX Probe-Datalogger

  • Select from one up to 6 gas sensors, plus temperature and %RH, in a single probe-datalogger, from a choice of 23 different gasses plus TVOCs
  • Connect multiple probes (2, 3, even 4) simultaneously to a single meter/monitor (virtually an unlimited number to the cloud)
  • In addition, options for Particulate, Airflow, Differential Pressure, and Barometric Pressure dependent on the meter(s) that are connected
  • DirectSense XM 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
  • Connect to a rugged GrayWolf manufactured meter/monitor, to a rugged GrayWolf supplied Windows Tablet/Android device, or to your own iOS, Android, or Windows phones/tablets/laptops/PCs
  • Log portable spot measurements, or trend log (unattended) over hours/days/weeks/months
  • Store enhanced survey information via the choice of platforms interfaced; data, text, audio, photo, video notes and more…
  • Auto-attach calibration details and more to data files
  • On-board sensor tips; government & industry guidelines, cross-sensitivity info and more…
  • WolfSense®PC Windows data transfer and feature-rich reporting software is included
  • Optional Advanced Report Generator software makes detailed report production ultra-efficient
  • Our optional GrayWolfLive® cloud platform enables remote access to live and logged Toxic Gas data, from one or multiple GrayWolf probes, on your smartphone or on just about any internet connected device. View data as live readings, tables, gauges, and/or graphs. Send alerts via e-mail, or text if hi/low setpoints are exceeded. Click here for more info.
  • The DirectSense XM comes with a charging cradle (that doubles as a stand), wall-mount bracket, and brass threading (for attaching a tripod or belt clip)
  • Extremely easy-to-use
AdvancedSense XM - Advanced Environmental Instrumentation for Toxic gas applications.
Up to six (6) gas sensors plus %RH and °C/°F (8 total) in a single probe. Multiple probes may be connected to AdvancedSense XM meters, up to 32 parameters total
Connect via Bluetooth LE wireless direct to Apple iOS and Android smartphones, iPads, and tablets with free apps (requires a radio card shipping July 2021 forward). Single probes via Bluetooth LE or multi-probes via Wi-Fi.

Toxic gas sensors are available for measuring Ozone (O3), Ammonia (NH3), Sulfur Dioxide (SO2), Nitrogen Dioxide (NO2), Nitric Oxide (NO), Carbon Monoxide (CO), Hydrogen Sulfide (H2S), Hydrogen Cyanide (HCN), Hydrogen Chloride (HCl), Oxygen (O2), Chlorine (Cl2), Arsine (AsH3), Diborane (B2H6), Phosphine (PH3), Phosgene (COCl2), Silane (SiH4), Chlorine Dioxide (ClO2), Fluorine (F2), Hydrogen (H2), Hydrogen Fluoride (HF), Carbon Dioxide (CO2), Ethylene Oxide (EtO), and low-range Formaldehyde (HCHO).

Up to 6 smart gas sensors, in addition to a smart relative humidity and temperature sensor, can be configured into a single DirectSense XM-8 probe. Or choose the more economical DSXM-5, or DSXM-3 probe-logger versions when a lower number of available sensor slots is sufficient.

GrayWolf multi-gas, toxic gas monitors, meters, detectors and instruments efficiently log your data and enable enhanced documentation for your surveys by means of a broad choice of reliable smart sensors, advanced software, and the power of mobile computing.

Optional GrayWolfLive™ software allows remote access to instrument data & notes via smartphones, iPads, Droids, PCs, etc.

Windows Tablet PCs may alternatively be connected, via cable or Bluetooth wireless to single or multiple probes

Optional PCC20 Hard Shell Security Case for unattended, long-term trending
