Conductivity Dissolved Oxygen pH Meter

A conductivity meter measures the conductive ability of a solution through electrodes, reflecting ion concentration; a dissolved oxygen meter uses a membrane electrode to detect the diffusion current of oxygen molecules in water; a pH meter determines hydrogen ion concentration through the potential difference between a glass electrode and a reference electrode. The three are used to monitor water purity, biological oxygen demand, and acidity or alkalinity, respectively, and are commonly applied in wastewater treatment, aquaculture, and chemical production.
Selection
When selecting, consider matching the measurement range to the sample characteristics. The conductivity should cover common aqueous solutions from 0 to 200 mS/cm, the dissolved oxygen range should be 0–20 mg/L, and the pH meter range should be 0–14. Pay attention to the durability of the electrode material, the temperature compensation function, and the simplicity of the calibration method. Choose between portable or online models based on the usage scenario, and check the protection rating to suit the environmental conditions.
