3DATX Corporation is a Buffalo, NY based company that manufactures next generation emissions measurement technologies for the transportation and power generation markets. We manufacture a range of accurate, low-cost, and ultra light-weight portable emissions measurement systems (PEMS) that make field testing, industry and academic research, and regulatory compliance screening practical on a mass scale. A significant advantage of the 3DATX iPEMS (integrated Portable Emissions Measurement System) design is the Modular Sensor Cartridge design. The 3DATX parSYNC is the only Particulate Measurement unit in the industry with commercially available field calibration capabilities (e.g. CA/GE System). Our unique miniaturized multi-chamber and replaceable sensor cartridges provide its user the capability to hot-swap while in the field. This eliminates down time and provides significant advantage to the number of tests that can be completed each day.
