Keep your meters and testing equipment running effectively and accurately by grabbing a Bluelab Replacement pH Probe. This replacement works with the Bluelab Combo and pH meters, along with the Bluelab Guardian Meter. Eventually, your original probes will wear out through normal use, and start to give inaccurate readings toward the end of their life. At this point, you'll need to replace the probe to keep the meter running efficiently. With proper care of your probe, such as keeping the tip wet and monthly cleaning/calibration, you can get a long, fruitful life from it. However, nothing lasts forever. Keeping a Bluelab Replacement pH Probe on hand will ensure you don't have any downtime with nutrient testing.
