Where PH 0 Will be very acidic, PH 7 will be neutral and PH 14 very alkaline. Water is near a PH 7 and this is usually around here that we will need to monitor PH of many things. 【Specification】 Heating voltage: 5±0.2V (AC -• DC) Working current: 5-10mA The detection concentration range: PH0-14 The detection range of temperature: 0-60 centigrade The response time: ≤ 5S Stability time: ≤ 60S Power consumption: ≤ 0.5W The working temperature: -10~50 centigrade (the nominal temperature 20 centigrade) Working humidity: 95%RH (nominal humidity 65%RH) Service life: 3 years 【How To Use】 1. Po Pin is the analog output pin 2. Voltage input can be 3.3v-5v 3. Blue potentiometer near BNC metal adjust the pH value.When adjust pH value need to take a wire to short the BNC. 4. Recommended step 3 adjust to 2.5V for pH 7.0. 0V = pH0, 2.5V = pH7, 5V = pH14. Calibration may had tolerance 10%. 5. Connect Po pin to analog input pin. 6. Example testing procedure. You may prepare 3 container, one for neutral, one for acidic and one for alkaline. 7. Put the probe to alkaline solution, and wait for 10-30second. Read the result. 8. Put back the probe to neutral solution. Wait for 10-30s. Read result. 9. Put the probe to acidic solution, wait for 10-30s. Read result. PRECAUTION! Never probe alkaline solution and directly switch to acidic solution! It may damage the sensor! Also each reading took 10s to 1min. The longer waiting time the accuracy is. 【Pin description】 1.
