GrayWolf's IAQ kits harness leading edge sensor technology with the power and performance of mobile computing.  Efficiently display, document, access educational information (on-site) and report on IAQ parameters.

AdvancedSense Platform:

  • display measurements in realtime
  • access sensor tips, IAQ documents and guidelines on-screen
  • store snapshot readings, trend log over hours/days/weeks
  • attach photos, word field forms, time stamped event notes, calibration history and other info to data file


  • highly accurate, extremely fast response sensors
  • perfect for both quick walk-through surveys and for long term IAQ trending
  • track VOC's over time
  • rapidly bloodhound VOC sources or determine optimum locations and
  • time to take air samples for VOC specification via lab analysis
  • powerful screening tool
  • VOC, CO2, CO, %RH, Temperature, (Toxic)

One specific gas sensor slot (additional to CO) is available on the IQ-610, choose from:

  • Ozone (available in rental pack)
  • Ammonia
  • Chlorine
  • Hydrogen Sulfide
  • Nitrogen Dioxide
  • Nitric Oxide
  • Sulfur Dioxide
  • Oxygen
  • Ethylene Oxide
  • HCN, HIL, H2, SiH4, AsH3, PH3, ClO2, COCl2, HF or F2
  • Optimize the balance between ventilation energy efficiency and occupant performance (and health)
  • Easily establish baseline data and respond immediately to complaints
  • Test conditions before and after building modifications
  • Screen for additional testing requirements
  • Bloodhound pollutant sources

DirectSense probes can also plug directly into a Windows 10/8/7/XP via USB port and GrayWolf's WolfSense LAP software.


Carbon Dioxide (NDIR) Range: 0 to 10,000 ppm
  Accuracy ± 3% rdg ± 50 ppm
Carbon Monoxide>:  (electrochemical) Range:  0 to 500 ppm
  Accuracy: ±2ppm <50ppm, ±3%rdg >50ppm
VOCs: (PID) Range: 5 to 20,000 ppb
  (user selectable units: ppb, ppm, μg/m3, mg/m3)
  Resolution 1 ppb, L.O.D. <5 ppb
  10.6 eV PIDs do not respond to VOCs with ionization potentials >10.6,such as ethane, methane or formaldehyde. However, they do respond to the vast majority of VOCs. Standard calibration is to Isobutylene. Users may calibrate to alternative VOCs
Relative Humidity: (capacitive) Range: 0 to 100 %RH
  Accuracy: ±2%RH <80%RH (±3%RH>80%RH)
Temperature: (Pt100) Range: -10° to 160°F (-25° to +70°C)
  Accuracy: ±0.3°C
Response Time: All sensors exhibit 90% response <1 minute
Probe Dimensions: 5cm diameter x 30cm length
Probe Weight: with batteries 0.7kg
Power: 2 x D cells, typical probe battery life 60+hours
Operating Range:  
PID (VOC) sensors: 0 to 90%RH, -15 to 60°C
Probe and other sensors: 0 to 98%RH (non-condensing), -15 to 60°C
PC software requirements: Windows 10/8/7/Vista/XP
