Specification: Item Type: PH Electrode Probe Material: ABS Heating Voltage: 5±0.2V (AC DC) Working Current: 5±10mA Detection Concentration Range: PH0-14 Temperature Detection Range: 0-80℃ Response Time: ≤5S Stable Time: ≤60S Power Consumption: ≤0.5W Working Temperature: -10℃ to 50℃ (nominal temperature 20℃) Working Humidity: 95% RH (nominal humidity 65% RH) Service Life: 3 years Output: Analog voltage signal output Precautions When Using Electrodes: 1. Use fresh buffer solution. 2. Open the electrode protection sleeve. 3. Measure the clearance and rinse the electrode with deionized water. 4. Stir the buffer and sample: a) Always stir at the same rate; b) Stir first and then measure. 5. When preparing the pH electrode, rinse the electrode with distilled water before and after measurement. Use a cloth without linen to absorb excess moisture from the electrode head and avoid rubbing the electrode ball, as it may generate static electricity and interfere with accurate pH measurement.
