Bluelab Probe Care Kit pH + Conductivity

Everything in the Bluelab Probe Care Kit Two probes, two sets of tools, and they are not interchangeable. The pH Probe Cleaner pairs with a toothbrush, because a pH bulb wants bristles that can reach the glass and the junction. The Conductivity Probe Cleaner pairs with a chamois, because an EC electrode face wants wiping rather than scrubbing. Eight 20 mL single-use sachets come with them, two each of pH 7.0, pH 4.0, KCl storage and 2.77 EC. That is a full two point pH calibration with a spare, a storage top-up, and two conductivity checks. Three plastic cups keep the fluids apart, which is the whole reason they are in the box. What the Bluelab pH Probe Cleaner Actually Removes Cadence is where growers go wrong, in both directions. Bluelab asks for a two point pH calibration once a month, and more often under heavy use, continuous monitoring or organic nutrients. Conductivity works differently, because those probes drift very little and calibration stays optional there. So the monthly job is pH and the constant job is cleaning. Storage is the other half. A pH probe has to stay wet, which is what the KCl sachets are for, and that solution wants refreshing weekly. A probe left to dry out is not finished. It needs rehydrating and a fresh two point calibration before its readings mean anything again. Keep the kit cool and dark with the lids tight. Key Features Covers both probes: pH and conductivity, with the right cleaner and the right tool for each. Toothbrush for pH: Bristles reach the glass bulb and the reference junction where film collects. Chamois for conductivity: An EC electrode face wants wiping rather than scrubbing. Eight single-use sachets: Two each of pH 7.0, pH 4.0, KCl storage and 2.77 EC, at 20 mL apiece. A full two point calibration: Plus a spare, a storage top-up and two conductivity checks. Three cups, three fluids: So buffer, storage solution and standard never meet each other. Calibrate pH monthly: More often under heavy use, continuous monitoring or organic nutrients. Conductivity stays optional: Those probes drift little, so cleaning matters more than calibrating. Keep the pH tip wet: KCl storage solution, refreshed weekly, is what keeps a probe alive. Fits the whole Bluelab range: Any Bluelab meter, monitor or controller running pH or conductivity.
