Bluelab pH Controller Wi-Fi 24/7 Reservoir Monitoring
Bluelab’s Wi-Fi-enabled pH controller provides round-the-clock reservoir pH management from a mobile device. It includes Edenic integration for expanded control and the ability to disable Wi-Fi if desired. The system supports remote monitoring and adjustments to maintain ideal pH levels for hydroponic crops. Safety is enhanced by dose-lockout features and an auto-resume function after power loss, helping prevent over‑adjustment or missed dosing. A built-in peristaltic pump supports precise pH adjustments in both directions.
Smart EC pH Temperature Monitor For Hydroponics
This 3-in-1 WiFi tester tracks pH, EC, and water temperature via a smartphone app, enabling continuous remote monitoring. It features dual relay outputs to automate dosing for both pH up/down and nutrient solutions, reducing manual intervention. Smart alerting lets users set MIN/MAX thresholds for pH and EC, with auto-dosing actions to restore balance. The system supports automation across various hydroponic setups and interfaces with compatible control software for broader management.
Growlink Batch TankLINK
Growlink batch tankLINK provides real-time monitoring of EC, pH, temperature, and water level in your nutrient batch tank. Automated refill triggers can maintain uninterrupted nutrient delivery, reducing manual checks. The system ships with EC and pH probes and a temperature sensor, with water level inputs (water level sensor sold separately). It’s designed for reliability within Growlink OS and is manufactured in the USA, ensuring compatibility with Growlink ecosystem and scalable control for larger grow operations.
Bluelab Pro Controller Wi-Fi
Bluelab’s Pro Controller Wi-Fi offers comprehensive reservoir management, including pH, conductivity, and temperature monitoring with remote access via mobile devices. Optional Edenic control augmentation enables expanded management of dosing and monitoring. Probes are replaceable to preserve accuracy over time, and safety lockouts plus auto-resume after power loss help maintain stable conditions. The system’s compatibility with Bluelab dosers supports automated nutrient and pH dosing, delivering consistent environmental control for hydroponics and indoor farming.
DANOPLUS Smart pH ORP Controller
DAOPLUS’ smart controller connects via Tuya app to monitor pH, ORP, and temperature in real time. It features dual power plug relays to automatically operate devices like solenoid valves, CO2 regulators, or dosing pumps. The 3-in-1 capability allows simultaneous measurements of pH, ORP, and temperature, with detachable, replaceable BNC electrodes for ongoing accuracy. remote monitoring helps maintain precise chemical balance in hydroponics, aquariums, and other water-based systems.
pH Controller with Dual Relay Output & Dosing Pump
This digital pH controller provides precise pH measurement and control for various aqueous solutions. It supports automatic dosing in up and down directions, with temperature compensation and a user-friendly LCD for real-time data. The device auto-displays max/min/avg data and offers a three-day chart view, helping growers track pH and temperature trends to maintain stable nutrient uptake and plant health.
Bluelab IntelliDose Controller Kit
Bluelab’s IntelliDose kit delivers 24/7 reservoir pH, EC, and temperature control with Wi-Fi connectivity. It supports multi-nutrient dosing and comes with replaceable probes for sustained accuracy. Edenic integration enables advanced remote monitoring and control, while safety features like dose-lockouts and auto-resume after power loss protect crops from fluctuations. Four outputs support irrigation control, making it suitable for NFT, DFT/DWC, soil, and other growth systems, giving growers flexible management options.
Buying Guide: Key Considerations And Comparisons
- Remote monitoring capabilities: Look for Wi-Fi or app-based control to monitor pH, EC, temperature, and water level from your phone or computer.
- Automation and dosing: Systems vary from single-parameter controllers to multi-nutrient dosing kits. Consider how many nutrients and additives you need to manage.
- Safety features: Dose lockouts, auto-resume after power loss, and alarms help prevent over- or under-dosing and keep plants safe during outages.
- Probes and replaceability: Replaceable pH and EC probes extend device lifespan and maintain accuracy over time; ensure compatible spare parts are available.
- Compatibility with tanks and setups: Some controllers integrate with tanks, NFT/DFT/DWC systems, or irrigation controllers. Check compatibility with your setup and planned expansion.
- Alerts and notifications: Customizable thresholds and real-time alerts help you respond quickly to drift or equipment faults.
- Ease of use and data history: A clear interface and data-trend displays (Max/Min/Avg charts) support ongoing nutrient optimization and troubleshooting.
- Cost of ownership: Factor in sensors, pumps, and potential replacement parts, plus any required ancillary equipment for full automation.
- Support and ecosystem: A well-supported brand ecosystem (software updates, compatibility with Edenic or Growlink platforms) can simplify long-term management.
When selecting, prioritize systems that align with your scale, preferred control style, and future expansion plans. For tight spaces and smaller tents, compact controllers with reliable app access may suffice. For larger grows with advanced nutrient programs, multi-nutrient dosing and robust safety features become more critical. Always verify probe availability and the ease of integrating with existing dosing pumps or irrigation controllers to minimize setup complexity.
