pH controller APX1-G2 is an instrument used to measure, monitor and automatically adjust the pH value of liquids. It is commonly used in a variety of industrial processes and laboratory applications to ensure that the pH of liquids is within the required range. The pH transmitter APX1-G2 has a differential signal, supports solution grounding, and can eliminate some solution leakage interference." This description refers to a specially designed pH transmitter with the following key functions:
Differential Signal: This pH transmitter uses differential signal measurement technology. In pH measurements, differential signaling is usually achieved by simultaneously measuring the potential difference between a working electrode and a reference electrode. This helps reduce the impact of external interference because differential measurements eliminate common-mode noise, improving measurement accuracy.
Supports solution grounding: This means that the pH transmitter can have an effective ground connection to the solution. In some cases, solutions may contain electrical charges or conductive substances that may cause electrical or inductive interference if not properly grounded. A pH transmitter that supports solution grounding ensures a good electrical connection and helps reduce the effects of electrical interference.
Eliminate partial solution leakage interference: This is a function for specific problems. Some solutions may carry a weak current or leakage, which may interfere with pH measurements. This pH transmitter is equipped with features that partially offset or suppress this leakage interference to ensure accurate pH measurements.
The pH transmitter APX1-G2 produced by Daruifuno is designed to provide more accurate and stable pH measurement in a variety of applications by using differential signal measurement technology and supporting solution grounding, as well as coping with solution leakage interference under specific circumstances. Reliable pH data, especially suitable for environments with high requirements for pH measurement accuracy, electrical interference and leakage interference.
