About

Watchlog Connect

Features
Read full description

Watchlog Connect is a monitoring and reporting app for Hydrotechnik sensors. Add pressure, temperature and flow sensors and watch live data on a chart with dual Y-axes, a crosshair and event markers, or as live tiles if you prefer numbers at a glance. Build calculated channels from your readings, including differential, up to 24 in total. Set alarms per channel and get a system notification when a reading breaches its limits. Record sessions to disk at intervals from 5 ms up to 10 s, depending on the sensor type. Recordings keep writing through the whole session and survive an app restart, so a dropped connection does not cost you the data. Reopen, compare and export past sessions whenever you need to, or export CSV data with full precision and millisecond timestamps. Generate multi-page PDF reports with charts, channel summaries, alarm breaches and event markers. Watchlog Connect is free to use, with the full sensor set, live charting, recording, alarms, CSV export and PDF reports included at no cost. Connect Plus is an optional annual licence that adds CAN bus acquisition using a Watchlog CAN to Bluetooth bridge. Available in English, German, French, Italian, Spanish and Japanese.
