Software Development


We have extensive experience in many areas of software design and development, with particular expertise developing scientific and engineering applications. DETech’s software developers and engineers design applications to save time and money. Our software addresses a wide range of practical issues, from large-scale, research-based applications [e.g., U.S. EPA’s “Air Compliance Advisor (ACA)”], to small-scale software applications [e.g., U.S. Army’s “CHPConvert”].

The CHPConvert utility is used at all of the U.S. Army’s chemical agent stockpile sites to quickly and efficiently perform routine calculations and conversions required of Army Hazard Analysts. DETech also has extensive experience in testing and evaluating software applications, as well as providing training on the use of software applications.
