Bluelab Probe Care Kit – pH & EC Calibration and KCl Storage Solutions | 8-Sachet Set

Bluelab Probe Care Kit – pH & EC Calibration and KCl Storage Solutions All the calibration and storage solutions your pH and conductivity probes need — in one convenient kit. The Bluelab Probe Care Kit (solutions set) provides eight single-use sachets covering every step of professional probe maintenance: two-point pH calibration, EC conductivity verification, and KCl probe storage. Accurate probes start with fresh, uncontaminated calibration solution. Single-use sachets eliminate the drift and contamination risk of shared bottles — so every calibration is as accurate as the first. Tear open, calibrate, discard. No measuring, no mess, no guesswork. What's Included ✅ 2x pH 4.0 Calibration Solution sachets — 18 ml / 0.6 fl oz each — acidic reference point for two-point calibration ✅ 2x pH 7.0 Calibration Solution sachets — 18 ml / 0.6 fl oz each — neutral reference point for single- and two-point calibration ✅ 2x 2.77 EC Conductivity Standard Solution sachets — 18 ml / 0.6 fl oz each — for calibrating EC/conductivity probes and meters ✅ 2x KCl Storage Solution sachets — 18 ml / 0.6 fl oz each — keeps pH probe membranes hydrated and extends probe lifespan Technical Specifications Brand Bluelab SKU MIX18B-2 Total Sachets 8 (2 of each type) Sachet Volume 18 ml / 0.6 fl oz each pH Calibration Points 4.0 (acidic) and 7.0 (neutral) EC Calibration Standard 2.77 EC Storage Solution KCl (potassium chloride) Format Single-use tear-open sachets Country of Origin New Zealand Weight 10 oz How to Use pH Calibration: Use pH 7.0 sachet first (neutral point), then pH 4.0 sachet (acidic point) for two-point calibration. Always use fresh solution — never reuse sachets. EC Calibration: Use the 2.77 EC sachet to verify and calibrate your conductivity probe or meter. Probe Storage: Fill the probe storage cap with KCl solution to keep the pH probe membrane hydrated between uses. Never store a pH probe dry. Compatible With Works with all Bluelab pH and conductivity probes, meters, monitors, and controllers, as well as any third-party pH or EC probe requiring standard calibration buffers. Ideal For Hydroponics and indoor growing — regular nutrient solution pH and EC verification Aquariums and aquaculture — water quality monitoring Laboratories and educational institutions Environmental and field water testing Need Tools Too?
