Bluelab Meters, Controllers & Calibration Solutions constitute a comprehensive hardware and software ecosystem for monitoring and managing critical growing parameters, primarily pH and electrical conductivity (EC). This portfolio supports every stage of commercial agriculture, from quick spot-checks with durable handheld pens to continuous monitoring and automated control via Wi-Fi-enabled systems. Central to maintaining this precision is a dedicated suite of calibration and maintenance solutions.
Core Handheld Measurement Pens and Meters
This category provides the foundational, portable tools for daily measurement of solution and substrate conditions. The Bluelab pH Pen is a core tool for measuring pH and temperature in nutrient solutions. It offers a compact, waterproof design, a double-junction probe for accuracy, and requires simple 2-point calibration with a 30-day reminder. For a more advanced and connected solution, the Bluelab OnePen integrates pH, conductivity (EC), and temperature measurement into a single, Bluetooth-enabled device. It features a replaceable probe, simultaneous display of pH and EC, and connectivity to the Edenic app for data management. For dedicated nutrient measurement, the Bluelab Conductivity Pen measures EC and temperature. The iconic Bluelab Truncheon Nutrient Meter and its higher-range Commercial Truncheon Meter are known for extreme durability and simplicity. They feature an LED display, require no calibration, are fully waterproof, and are designed for both measuring and stirring nutrient reservoirs. Moving beyond solution, the Bluelab Soil pH Pen is designed for direct measurement of pH and temperature in soil, coco coir, or rockwool, eliminating the need for messy slurries. For comprehensive root-zone analysis, the Bluelab Pulse Multimedia EC/MC Meter measures moisture content (MC), EC, and temperature directly in the growing media.
Advanced Monitoring, Control, and Accessories
This segment caters to operations requiring constant oversight, automation, or specialized components. For automated management, the Bluelab pH Controller Wi-Fi and Bluelab Guardian Monitor Wi-Fi (and its In-Line Connect variant) enable remote, continuous monitoring of reservoir conditions with configurable alerts. They integrate with the Bluelab Pro Controller platform. The Bluelab Peripod modules (L3, M3, M4) are sensor nodes within this ecosystem, designed for scalable deployment. To ensure longevity and performance, a full range of probes is available, including the Bluelab OnePen Replacement Probe, dedicated pH probes (pH Probe, Leap pH Probe, In Line pH Probe), and a Temperature Probe. Physical protection is provided by the Bluelab Meter Carry Case and Shockproof Rubber Boots.
Calibration and Maintenance Solutions
Consistent accuracy across all measurement devices depends on a disciplined regimen supported by dedicated products. Essential for calibrating pH devices are Bluelab pH 4.0 and pH 7.0 Calibration Solution (with pH 10 also an option for high-range measurements). For conductivity meters, the Bluelab 2.77 EC Conductivity Standard Solution is used for accuracy verification and troubleshooting. Proper electrode maintenance is critical. Bluelab pH Probe KCI Storage Solution is used to keep pH probes hydrated. For comprehensive upkeep, Probe Care Kits are available for pH, conductivity, or as a combined bundle, containing the necessary solutions for cleaning, calibration, and storage.
