THROUGH THE Cultivator's LENS Product Evaluation

  • You are replacing a worn sensor because your current meter is showing inaccurate readings or failing to stabilize on a set point.
  • You are adding a dedicated probe to an additional reservoir because you need to track pH levels across multiple tanks simultaneously.

  • The 2-metre cable gives you enough room to mount your controller on a wall while keeping the probe submerged in the tank.
  • The included probe holder is a reliable way to keep the tip positioned correctly without it knocking against the reservoir walls.

  • Growers who switch to this probe as a replacement say they immediately regained the consistent readings they were missing from an aging sensor.
  • Users who keep a spare on hand mention that having a calibrated backup allows them to swap out a failing probe without any downtime in their feeding schedule.

Bluelab pH Probe - 2m / 6.6ft Cable

A failing pH probe can throw off readings on an otherwise reliable meter, and not every replacement is built to the same standard as the original. The Bluelab pH Probe solves this with dependable double-junction technology in a standard BNC-connector design, compatible with any Bluelab handheld meter, monitor, or controller that uses a BNC connection.

A durable polycarbonate body and fully waterproof construction hold up to daily use in solution, while a 2-metre (6.6ft) cable gives you reach into reservoirs and tanks that sit away from your meter. Device resolution of 0.1 or 0.01 pH, depending on your paired meter, keeps readings precise across Bluelab's handheld and monitoring lineup.

A KCl-filled storage cap keeps the probe hydrated between uses, and an included probe holder with suction cup gives you a stable mounting point in reservoirs and tanks — making this probe a straightforward, dependable replacement for solution-based pH monitoring.
