We are committed to advancing real driving emissions solutions with you.

About 3DATX

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.
