  • Top 5 Tips to Consider When Calibrating Your pH Meter - Hanna Instruments Slovenija
    calibrating your meter But how do you know when calibration is necessary or why your readings are off Today we will provide you with a list of tips to consider when you are calibrating your meter whether it be the first time or the one hundred and sixty eighth time 1 Always read your manual Calibration procedures change based on which meter is used In order to best understand your specific meter it is important to read the manual when you receive your pH meter 2 Make sure you have all of the necessary pH buffer you need When performing a pH calibration it is important that the appropriate buffers are used For example if you want to measure something with a pH of 9 and you only calibrate your pH meter to pH 7 you may not get an accurate measurement This is because pH measurements are most accurate when calibration points bracket the measurement You should also check your buffers expiration date and how long the buffer has been open for Some buffers like the pH 10 buffer expire much sooner than the expiration dates once they are opened 3 Calibrate Often For the most accurate measurement it is suggested that you should calibrate your meter every time you perform a new set of measurements Calibration can also help identify a problem with your electrode We suggest calibrating your meter Upon first use After a long period of storage When performing a new set of measurements 4 Be aware of your Slope and Offset Your slope and offset have a significant impact on the condition of your electrode Hanna Instruments recommends that the offset does not exceed 30mV and that the slope percentage is between 85 105 If you have a bad offset this could mean that you
