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

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
