Sniffer4D Mapper - The Data Visualization and Analytical Software
Sniffer4D is able to sense up to 9 gases and particle concentrations at one time. Users can flexibly choose or alter their sensor configurations that suit their applications and budgets.
Ambient Air Monitoring
PM2.5 | PM10 | SO2 | CO | NO2 | O3 | TVOC | Odor (OU)
Oil & Gas Plant Leak Detection TVOC | CH4 | H2S | SO2
HAZMAT TVOC | CH4 | CO | CO2 | Cl2 | O2 | NO2 | H2S
TVOC | SO2 | CO | NO2 | O3 | PM1.0 | PM2.5 | PM10 | CxHy / CH4 /LEL | H2S | HCl | TSP/PM100 | NH3 | CO2 | HCN | H2 | PH3 | Cl2 | O2 | NO | Odor (OU) | High-Resolution CH4*
* Externally-mounted modules that do not occupy the internal space.
Sense Up to 9 Gases at a Time
Advanced Real-time Visualization
Sniffer4D Mapper software visualizes and analyzes data from one or more Sniffer4Ds in real-time. Three types of visualization (2D grid/2D isoline/3D point cloud map) provide intuitive & insightful information for decision makers.
From data collection to result delivery
One-click Result Delivery
After a mission, simply click a button to generate a mission report containing key results, or a CSV datasheet containing all the raw data. Reporting your work has never been easier.
Compare long-term datasets from Sniffer4D and a local reference monitoring station (placed at the same location) to determine the calibration parameters.
Inject calibrating gases with known concentrations to determine the calibration parameters.
Use local AQI information to roughly determine the calibration parameters.
Every Sniffer4D is factory calibrated before shipped out. We recommend re-calibrating the device every 12 months. There are generally 3 ways to calibrate Sniffer4D.
Sniffer4D provides superior data quality and offers up to part-per-billion (ppb) detection resolution for specific modules.
Even gases in ppb-level concentration can be sensed and analyzed with accuracy.
Achieved through: Proprietary ultra-low-noise signal processing circuits; State-of-the-art sensing components;
Proprietary environmental and individual difference compensation algorithms; Rigorous quality control process.

Limited Detection Range
Traditional detection methods have difficulties in achieving large-scale detection due to complex emission sources in the city.
Traditional detection methods much depend on handheld devices, unable to finish large-area detection missions with efficiency.
Hard to locate emission sources with effective deployment in HAZMAT scenarios.
Low Quality Data
Limited gas information for a thorough data analysis.
