Bluelab Combo Meter & Conductivity Probe Care Kit Hydroponics

This kit contains probe care instructions, plastic cups, single-use BlueLab Calibration Solutions, pH probe cleaner, and BlueLab conductivity probe cleaner. It also includes a BlueLab pH probe, KCl storage solution (100ml / 3.3 fl oz). This is designed for pH and conductivity probe maintenance. I have kept the probe tip maintained; the device has never been used. I am open to a fair offer. MSRP for all this is over $400 CAD
