What Comes in the Bluelab Probe Care Kit Conductivity
Five things, and each one does a job. A bottle of Bluelab Conductivity Probe Cleaner, which is the chemistry. A Bluelab chamois, which is the tool that reaches the electrode face. Two 20 mL single-use sachets of 2.77 EC standard for checking the result. A plastic cup to pour into. Written probe care instructions, which are worth reading once even if you have done this before. Bluelab puts the point plainly: an instrument is only as accurate as its probe is clean. Nutrient salts build a film on the electrode face. That film sits between the solution and the sensor, and the display quietly stops matching the tank.
Using the Conductivity Probe Cleaner and Chamois
There is one symptom worth memorising. A conductivity probe that has gone dirty reads low, not high. So a tank that suddenly seems weaker than the feed chart says is a cleaning job before it is a nutrient problem. Work the cleaner over the electrode face with the chamois, rinse in fresh water, then pour a sachet into the cup and read it. Landing on 2.77 means the probe is back. The sachets are the quiet advantage here. Single use means there is no open bottle to contaminate and no temptation to tip a used sample back. When they run out, the same standard comes in 20 mL sachets, 250 mL and 500 mL. There is one limit to know. This kit is conductivity only, so a bench with a pH probe on it wants the pH and Conductivity kit instead.
Key Features
- Cleaner and chamois together: The chemistry and the tool that reaches the electrode face, in one kit.
- Two single-use 20 mL sachets: Fresh 2.77 EC standard each time, with no open bottle to contaminate.
- A dirty probe reads low: That is the tell. A weak looking tank is often a cleaning job, not a feed problem.
- Plastic cup included: Because the probe never goes into the bottle or the sachet itself.
- Written care instructions: Worth one read even for a grower who has cleaned a probe before.
- Fits the whole Bluelab range: Any Bluelab meter, monitor or controller with a conductivity probe.
- Check after you clean: Rinse, pour a sachet, and look for 2.77 before trusting the tank reading.
- Restocks easily: The same standard comes in 20 mL sachets, 250 mL and 500 mL bottles.
- Conductivity only: A bench that also runs a pH probe wants the pH and Conductivity kit.
