Air Monitoring Probe and Improved IAQ

Building on 20 years of customer feedback, the all-new range of DirectSense II smart probes are being introduced by GrayWolf. These air monitoring probes accommodate from two (2) up to eight (8) plug-and-play smart sensors into a single hand-held, desktop or wall-mounted housing. Choose from 25 different indoor air quality, green building, industrial hygiene and HVAC parameters including; TVOCs (PID), Carbon Dioxide (NDIR), Carbon Monoxide, Ozone, Nitrogen Dioxide, Ammonia, Sulfur Dioxide, Chlorine, Hydrogen Sulfide, %RH, °C/°F and many others.

The DirectSense II probes connect to GrayWolf’s AdvancedSense® meters which enable additional parameters such as Particulates, Differential Pressure, Air Velocity and Formaldehyde. They may also be connected to GrayWolf-supplied tablet PCs, and Windows PCs for real-time display, data logging and/or remote access. Connection is via cable and/or Bluetooth wireless (both come as standard). In addition to the broad offering of parameters, there are also different sensor ranges to choose from for some of those parameters to best fit specific applications.

The probes are housed in a rugged enclosure with rubberized grips for hand-held use and for added drop protection. Brass threading on the back accommodates belt clips (convenient for walk-thru surveys), and tripod mounting when long-term trend logging. A secure hatch allows user access to replace or swap the smart sensors. Calibration and additional sensor specific data is stored on a micro-board, which makes the smart sensors truly “plug-and-play”. Yet, there is no significant loss of limits-of-detection (crucial for IAQ applications) or reduction of other sensor performance due to any noise introduced by these convenient/efficient “smart” boards. In fact, CO2 and TVOC sensors achieve improved performance vs. GrayWolf’s original DirectSense probes.

The new probes have rechargeable Li-ion batteries and come with a charging stand that includes wall-mounting brackets for continuous monitoring applications. The probe may alternatively be powered from the connected platform (AdvancedSense, tablet or PC). A built-in fan eliminates sensor heating effects and improves sensor response time.

Data logging can be initiated from the probe using a convenient, tactile LOG button. Extensive, versatile features are also enabled when connecting to the various available platforms. These include built-in cameras/microphones/virtual keyboards (all for secure, efficient documentation of data files), on-board training/application videos, Wi-Fi remote data access and alerts, and much more.

The DirectSense II probes may be used for walk-thru surveys, long-term trending or continuous monitoring. Green building applications such as USGBC LEED EQc4 pre- occupancy, IWBI WELL air screening/monitoring and GBCI Arc “Human Experience” testing are comprehensively fulfilled. Many other IAQ, HVAC, IH, IVF, R&D and other applications are also well accommodated.
