Q1: What does this water quality tester measure?
A1: This tester measures pH, TDS (Total Dissolved Solids), EC (Electrical Conductivity), Salinity, and Temperature, providing a comprehensive analysis of water quality.
Q2: Can I use this tester for drinking water?
A2: Yes, it is suitable for testing drinking water, as well as water used in aquariums, aquaculture, hydroponics, pools, and agricultural applications.
Q3: Does the tester have automatic temperature compensation?
A3: Yes, it features an external high-precision temperature sensor that enables automatic temperature compensation (ATC), ensuring accurate readings in various environments.
Tips: After a period of use, the measurement accuracy decreases. How should it be maintained?
First, clean the electrode probe regularly to remove surface deposits and keep the probe clean. Second, calibrate according to the instruction manual. If the slope exceeds the range of 65%-150% after calibration, check if the electrode is aging. If necessary, replace it with an original RZS6930 dissolved ozone electrode. Additionally, avoid contact between the electrode and strong corrosive chemicals to prevent probe damage.
