DirectSense® II smart probes from GrayWolf Sensing Solutions are user configurable IAQ and toxic gas probes. They accommodate from two to eight plug-and-play smart sensors into a single hand-held, desktop, or wall-mounted housing. Users can 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 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 parameters, there are also different sensor ranges to choose from for some of those parameters to best fit specific applications.
The air monitoring 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 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 “smart” boards.
The IAQ and toxic gas 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 tactile LOG button. Additional features are also enabled when connecting to the various available platforms. These include built-in cameras/microphones/virtual keyboards (all for secure documentation of data files), on-board training/application videos, and Wi-Fi remote data access and alerts.
The DirectSense II IAQ and toxic gas 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 fulfilled. Many other IAQ, HVAC, IH, IVF, R&D, and other applications are also accommodated.
