Ppm and pH meters arrived

And don't forget to calibrate your pH meter every time before mixing a new watering! You have to understand that this device can lie every time, and you need to control the accuracy of its readings..... for example.... choose a "calibration solution" or prepare it from the packets of powder that come with the pH meter. Calibrate your device with the solutions and compare it with tap water...... as soon as the values stabilize in the tap water - remember them! Now tap water is one of your "calibration solutions," you can calibrate with tap water every time and with some common substances that everyone has at home, for example: - shampoo or black tea 5.5 pH - seawater 8 pH - bleach (chlorine-based) 12.5 pH - beer 4.5 pH - coca-cola 2.5 pH A small screwdriver comes with the pH meter, which you need to use to adjust the device by turning the calibration screw located on the opposite side of the screen. 😇👌 Place the powered-on device in the calibration solution, wait for the readings to stabilize, and turn the screw to the values that the calibration liquid should be around. After that, rinse your device in clean water and place it in another calibration solution, wait again and turn..... I do a full calibration on 3-4 bases once a month. But I calibrate the device daily on one base - well water with 8.3 pH 😇👌 Good luck, friend! 😇✊
