ZenTest-Smart Water Tester

ZenTest-Smart Water Tester connects your Bluetooth-enabled multi-parameter water testing device to your Android phone, turning field measurements into manageable data workflows. Log pH, conductivity, TDS, salinity, resistivity, ORP, and temperature readings with professional-grade accuracy—then organize, analyze, and share results instantly from your device.

Choose from four display modes to match your workflow. Simple mode gives you quick readings at a glance. Dial mode mimics traditional meter behavior. Graph mode reveals trends over time. Table mode displays detailed measurement records side by side. Switch between them depending on whether you're running a single test or monitoring changes across multiple samples.

The cloud-based data logger stores every measurement along with calibration history, linked assets, notes, and photos—all tagged with GPS location. Upload automatically after each session or log manually when connectivity is limited. Retrieve your data anytime, and share results with team members or stakeholders directly from the app.

Calibration becomes straightforward with step-by-step visual guidance. The smart self-diagnosis feature walks you through troubleshooting if something goes wrong, catching drift or sensor problems before they skew your results. Set alarm thresholds for any parameter, and the app alerts you when readings exceed your acceptable range.

ZenTest-Smart Water Tester also works as a standalone tester—use it without your phone by interacting with the device directly. This dual-mode design means your testing doesn't pause if your smartphone battery dies or loses signal. Whether you're monitoring wastewater treatment, lab quality control, pool chemistry, or environmental surveys, this app bridges mobile convenience with the reliability of dedicated water testing hardware.
