JFA300 Online concrete pH Meter for Aquarium Acidimeter Water
pH sensor is a combination electrode composed by glass indicative
electrode and reference electrode. pH measure, a measure method to
realize pH online monitor, according to measure potential
difference in solution by measuring working battery formed by
electrode and reference electrode, utilizing linear relationship
between the solution pH value need to be measured and electric
potential of working battery.
1. Favorable repeatability and stability.
2. Simple to clean and activate, with faster balancing speed.
3. Auto-temperature compensation function.
