Replace the probe (electrode) rather than the whole meter!
Easy to clean, low maintenance, gel filled (non-refillable) range of pH and soil pH replacement probes suitable for any meter, monitor or controller with a BNC fitting. Measure the pH of a water-based liquid, nutrient solution, soil solution or directly test soil pH.
Bluelab have specifically designed a replacement conductivity probe, temperature probe and pH probe with ATC for use with the Dosetronic Controller only. These probes cannot be used with any other Bluelab product.
