TDS/pH/Temperature 3-in-1 pH Meter for Water, 0.01 High Precision Water Quality Digital pH Tester, pH Measurement Range with 0-14, pH Pen TDS Water Test Meter for Drinking Water, Pool and Aquarium

Description

𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗰 𝗧𝗲𝗺𝗽𝗲𝗿𝗮𝘁𝘂𝗿𝗲 𝗖𝗼𝗺𝗽𝗲𝗻𝘀𝗮𝘁𝗶𝗼𝗻 Temperature can affect reading levels, our water pH meter's automatic temperature compensation can ensure that you're getting the best possible reading. Unlike other pH meter for water that only have a range of 0 °C-50 °C, ours pH meter for water has a even better range of 0 °C-60 °C (32 °F-140 °F). 𝗕𝗮𝗰𝗸𝗹𝗶𝘁 𝗗𝗶𝘀𝗽𝗹𝗮𝘆 Digital pH meter has a green backlit LCD to help you see your measurements clearly in any situation, with reliable and fast readings. The LCD screen is large and can display the numerical value directly. 𝗖𝗮𝗹𝗶𝗯𝗿𝗮𝘁𝗶𝗼𝗻 𝗽𝗛 𝗦𝘁𝗲𝗽𝘀 1. Before calibration, add the pH4.00/pH6.86/pH9.18 buffer powder into beaker with 250ml (under the temperature of 25℃) of distilled water, then stir until the powder has completely dissolved. 2. Press the ON/OFF button to turn on. 3. Press the TEMP / CAL button, adjust to pH mode. 4. Place the electrode in the pH 4.00/ 6.86/ 9.18 standard solution. 5. Wait for the readings to stabilize(usually 5~10 Seconds). 6. Press and hold the TEMP/CAL button for 6 seconds, then you can see corresponding value flashing 3 times which means calibration of pH is completed. 𝗡𝗼𝘁𝗲:Be sure to add water according to the required ratio, otherwise it will affect the accuracy of the calibration and increase the error. Do not turn on the switch of the pH meter in the air, which will interfere with the calibration of the pH meter. When measuring the same amount of solution, the pH value of the solution will produce errors with time and place changes. This change is normal, and it is not a wrong reading of the water test meter.
