About

SampleServe Field App

Features
Read full description

Saves the field person time, making them more productive, while also making them more accurate and efficient. Using SampleServe's web and mobile application we save the field sampling crew roughly 20% of their time on a typical sample collection investigation. •The field technician using the app receives all sampling details and instructions directly from the project management tool, automatically. •The Project Manager can track field technician activity and progress in real-time and review data as it’s being collected. •Bar-coded and QR coded sample bottle labels are printed in the field at the time of sampling. •Sample collection and custody is tracked in a clear and concise manner using our patented digital chain of custody (DCOC). •Photos of sampling locations and other significant features can be collected and available as part of the record. •An immutable and precise GPS and timestamp are collected with each significant event like sample collection and/or custody transfer. •Three-part authentication digital chain-of-custody is used to convey laboratory instructions to the laboratory in advance of sample arrival. It’s better and more accurate than paper COC. •QR coded custody seals for coolers are printed from the application. Know what’s in the cooler without having to open the cooler. •The application works with or without a wireless data connection. •Use of the mobile environmental field application is completely free.
