Description
A genuine replacement probe to bring a tired Bluelab meter back to full accuracy
This is the standard Bluelab pH Probe with a 2 metre cable and BNC connector, the same double-junction probe fitted to the Guardian Monitor and other BNC-connection Bluelab meters and controllers. A pH probe is a consumable part: drift, a slow response and readings that will not hold calibration are signs the glass bulb and reference junction have reached the end of their life, and a straight swap restores lab-accurate readings without replacing the whole unit.
Key Benefits
- Genuine Bluelab double-junction probe for a longer working life than single-junction alternatives
- Standard BNC connector and 2m cable, a direct fit for the Guardian Monitor and other BNC-fitted Bluelab units
- Waterproof polycarbonate body built for wet grow room use
- KCl-filled storage cap keeps the tip hydrated between uses
- Simple 2-point calibration against pH 4.0 and 7.0 or 10.0 solution
How to Use
- Disconnect the old probe from the BNC socket and connect the replacement, twisting to lock it in place.
- Calibrate in fresh pH 7.0 solution first, then pH 4.0 or pH 10.0 depending on your working range.
- Store with the KCl-filled cap on and keep the tip wet; never let a probe dry out between uses.
