Sensorex-Equipped Batch Tank Monitor for Fertigation Recipes The BTM ships with a Sensorex pH probe (±0.02 pH) and a matching Sensorex EC probe. Inputs also accept level sensors, flow meters, and a temperature element. The controller streams every reading into the Growlink app over Wi-Fi. You watch the recipe drift in real time from the grow floor or a laptop on the road. A 24 VDC global-plug supply, a mounting bracket, and the sensor kit all land in the box ready for a clean wall install. Nutrient Tank Monitor with OTA Updates and Smart Alerts Alerts fire when pH, EC, temperature, or level drift past your target band. The alert log keeps the history so you can audit a tank cycle after a bad batch. Over-the-air firmware updates roll out new logic without a service call — the controller pulls them when it next phones home. Wire the BTM next to a Nutrient Doser or Precision Irrigation Controller. Refills can run on auto once levels drop below your reservoir floor. Key Features Sensorex pH probe at ±0.02 pH / 0.01 pH resolution: Lab-grade readings on the nutrient that matters most to root uptake. Sensorex EC probe: Tracks TDS through the full grow cycle so feed strength stays inside the recipe band. Inputs for level, flow, and temperature: Wire tank floats, flow meters, and a temp element for full reservoir telemetry on one controller. Wi-Fi + Growlink app: Watch tanks from the floor or off-site, then adjust strategy from a phone or laptop without driving back. OTA firmware updates: Pulls new features and fixes over Wi-Fi — no truck roll, no USB. Active and historical alerts: Every drift event logs for review, with push notifications when a target breaks in real time. 24 VDC global power supply + mounting bracket included: Ships ready to land on a wall next to the batch tanks.
