Bluelab pH Controller Wifi

The Bluelab pH Controller Wi-Fi is an automated reservoir management device designed to continuously monitor and adjust pH levels within a nutrient solution. It operates as a dedicated pH control unit, measuring pH in real time and delivering controlled doses of pH adjuster to maintain a consistent setpoint without the need for frequent manual correction. Designed for reservoir-based growing systems, the unit combines measurement, dosing, and control into a single wall-mounted solution. It uses a built-in peristaltic pump to dose either pH up or pH down in one selected direction, allowing for stable and controlled adjustment over time rather than rapid correction. A separate temperature probe enables automatic temperature compensation, supporting reliable pH readings within the solution. The Wi-Fi functionality allows the controller to connect to the Bluelab Edenic™ app, providing remote access to pH data, system status, and configuration settings. This enables monitoring and adjustment without needing to be physically present at the reservoir, as well as access to historical data tracking and alert notifications. The system is designed with operational safety in mind, incorporating dosing lockouts and alarm conditions to help prevent overcorrection. It includes acid and alkali-resistant tubing for compatibility with common pH adjusters, along with replaceable components such as the pH probe and peristaltic pump to support ongoing maintenance. As part of the Bluelab control range, the pH Controller Wi-Fi is intended for growers requiring consistent pH stability in a reservoir, with the added benefit of remote monitoring and control through integrated connectivity.

Bluelab Leap pH Probe

The Bluelab Leap pH Probe is a reinforced, multi-environment pH probe designed for direct measurement in soil, substrate, and nutrient solutions. It connects to compatible Bluelab handheld meters, monitors, and controllers via a standard BNC connection, enabling accurate pH readings across both media and liquid applications. Engineered with Bluelab’s Leap™ technology, the probe is built to support consistent performance in demanding growing environments. Its reinforced spear tip allows direct insertion into soil and substrates for in-situ root zone measurement, while the same probe can also be used for continuous monitoring in nutrient reservoirs. The probe features a double-junction design to support reliable readings in a range of solution conditions and is fully waterproof for use in wet environments. It is supplied with a KCl-filled storage cap to maintain probe condition and ensure readiness between uses.

Bluelab pH Calibration Solution 4.0

Bluelab pH Calibration Solution 4.0 is a precision reference solution used to calibrate pH pens, meters, and probes, ensuring ongoing measurement accuracy in nutrient solutions and water. Regular calibration is essential for maintaining reliable pH readings, particularly in hydroponic systems where small variations can influence nutrient availability. This solution provides a stable pH 4.0 reference point and is used as part of a two-point calibration process alongside pH 7.0 calibration solution. By calibrating at two points, the pH device can correctly interpret both neutral and acidic ranges, helping maintain consistent and dependable readings across typical growing conditions. Bluelab recommends routine calibration to account for probe drift over time. Using fresh calibration solution during each calibration cycle supports consistent results and helps extend the functional reliability of pH measurement equipment. This solution is formulated specifically for compatibility with Bluelab pH products and is intended strictly for calibration purposes, not for storage or adjustment of pH in nutrient solutions.

Bluelab KCI pH Storage Solution

The Bluelab KCl pH Probe Storage Solution is a potassium chloride solution formulated specifically for storing and maintaining pH probes between uses. It is used within the probe storage cap to keep the probe tip hydrated, which is essential for maintaining probe performance and measurement reliability. Bluelab specifies that pH probes must always be kept moist and should never be stored dry. This solution provides the correct ionic environment for the probe tip, helping preserve its functionality and ensuring it remains ready for calibration and use. It is suitable for use with all Bluelab pH probes and pH pens. Regular use of KCl storage solution forms part of standard probe care, supporting consistent readings and extending the working life of the probe when used as directed.
