e-sens

e-sens is a Salt Lake City, Utah-based manufacturer of solid-state silicon sensor technology for real-time water quality monitoring and regulatory compliance testing, operating from 630 Komas Drive. The company's core platform is the ROAM portable field instrument, which uses pre-calibrated sensor cartridges to deliver electronic digital readouts of water quality parameters without reagents, manual calibration, or waste generation. Each cartridge lasts a minimum of 30 days or 100 tests, eliminating the consumable burden and calibration drift inherent in traditional analytical methods. The ROAM supports 23 distinct testing parameters across a zero-waste measurement workflow. e-sens pairs the instrument with a free, customizable field data collection app available on iOS and Android, providing real-time data transmission from any mobile device to central offices. The app integrates with existing LIMS and SCADA systems and can function independently as a compliance data management tool. A significant regulatory milestone came with EPA approval of the AMCD (e-sens) method for monitoring water compliance, positioning the platform as a validated alternative to conventional reagent-based testing for municipal and regulated water utilities. Markets served include municipal water and wastewater compliance monitoring, environmental field testing, and facility-grade water quality auditing where auditable, real-time data is required.
