Portable water quality testing pen

The portable water quality testing pen utilizes electrochemical sensors, which generate current signals through the contact between the electrodes and the water sample, and then convert these signals into water quality parameter values. It is used for on-site rapid detection of indicators such as residual chlorine and pH in water, making it suitable for daily monitoring in places like water treatment plants, swimming pools, and aquaculture facilities.
Selection
When selecting, focus on whether the detection parameters match the requirements, check the instrument calibration cycle and consumable replacement frequency, compare the service life of sensors from different brands, ensure the protection rating is suitable for the operating environment, and verify that the data storage and transmission functions meet recording requirements.
