Handheld field tester that lets water utility staff measure lead and other heavy metals at the tap in minutes.
Segura is a portable field instrument for measuring trace heavy metals in drinking water, built around anodic stripping voltammetry rather than the optical colorimetry most rapid field kits use. A handheld reader pairs with disposable screen-printed sensor strips whose electrode chemistry is mercury-free, and a single measurement resolves several metals at once instead of one analyte per test.
Segura targets water utilities and the field technicians who collect samples at the tap, a job served either by colorimetric strip tests that lose sensitivity at low concentrations or by centralised laboratory analysis that sets the accuracy benchmark but requires shipping samples and waiting days for a result. Segura offers its reading as screening evidence that flags exceedances for laboratory confirmation, not as an accredited compliance measurement.
