Dirt + New Prototype + On-Target™ = Remote Results FAST.

OCT 10TH, 2018

Access Sensor Technologies has built functional prototypes of a tool that can extract heavy metals from soil samples in the field. These extracts can then be analyzed using our On-Target™ technology. We are currently field testing these prototypes in the mountains of Southern Colorado. For more info, contact us at

meet tom and dan at the ises-isee annual meeting in Ottawa, canada

AUGUST 26TH-30TH, 2018

The ISES-ISEE Joint Annual Meeting starts in just a few short days and we are excited! Stop by our booth to meet Dr. Thomas Reilly and Daniel Miller-Lionberg to learn more about how Access Sensor Technologies has made sampling simple for epidemiologists! Are you ready for the revolution?


ISES-ISEE Annual meeting 

AUGUST 26TH-30TH, 2018

The Joint Annual Meeting of the International Society of Exposure Science and the International Society for Environmental Epidemiology (ISES-ISEE 2018) will bring together scientific experts and practitioners from academia, government, industry, and non-governmental organizations dedicated to the protection of health and environment. Exposure science and environmental epidemiology are dynamic fields that:

  • Develop and apply traditional and innovative methods for assessing exposures to environmental stressors and their health effects.

  • Address exposures to a broad array of environmental stressors as well as factors that contribute to or mitigate exposure.

  • Elucidate potential health effects from environmental stressors during the life cycle including outcomes from in utero development to death.

  • Promote interdisciplinary approaches to solving complex environmental public health problems.

The ISES-ISEE 2018 Joint Annual Meeting theme is “Addressing Complex Local and Global Issues in Environmental Exposure and Health.”

As the capital city of Canada, Ottawa is home to diverse and active community of scientists and policy makers engaged in local and global environmental exposure and health research. The ISES-ISEE 2018 Joint Annual Meeting will be inclusive to delegates from around the world, and will leverage local and international expertise to address complex local and global topics relevant to exposure science and environmental epidemiology.



Access Sensor Technologies makes on-site water testing and data logging a breeze with our On-Target analysis app that runs on a phone, tablet, or laptop. Simply dip the On-Target test card into the water, wait 5 minutes, and take a picture with the app for instant quantification of any of the metals in our expanding test library!




Our Youtube channel is meant for online support. Access Sensor Technology is founded on the idea that Sampling Should Be Simple. Due to that we aspire to have everything else be simple as well. Our Youtube channel holds information on both the Ultrasonic Personal Air Sampler (the UPAS ) and our On-Target Test Cards (Copper, Iron, and Zinc). Everything has been broken down for you to find what you need. The UPAS is broken down into process specific videos, allowing for time to be managed properly. On-Target card video are available to watch as well. 

Please Contact Us if you have any further questions, or concerns. 



In just the past few years, our UPAS and On-Target technologies have been utilized across the United States and at many diverse locations around the world. Our UPAS air sampling technology has been deployed in 20 countries, and our On-Target water testing technology has already been to 5 countries. The entire Access Sensor Technologies team would like to thank all of our early adopters and customers for helping make these innovative technologies a success!
