Aqua Master Tools offers a wide range of NIST-certified solutions for cleaning, calibration, and maintenance. These fluids are designed to ensure accurate readings and keeping our products in top condition. Additionally, all our solutions are compatible with all meters in the industry. Check out the Aqua Master P110 and the Aqua Master E50 Calibrating the PH Meter P110 Press the On/off button to start the meter. Press the MODE button to switch to pH on the display. Gently clean the electrode with distilled water and dry it off. Insert the meter in an upright position in pH buffer solution pH 7.01 •c (make sure this is 25 or 77 •F) and stir gently. Wait until the value on the display is stable. Press and hold the 0C/°F CAL button for 5 seconds until the value of the buffer solution is displayed. The meter will automatically recognise the buffer solution and calibrate itself. As soon as the meter switches back to the standard mode, calibration is complete. Gently clean the electrode with distilled water and dry it off. Repeat the process with pH 4.01 buffer solution. It is important to follow the above process order, always startcalibrating pH 7.00 and follow with pH 4.01. Carefully clean the meter after this process. Calibration is completed and the meter is ready for usage when all steps have been completed. Calibrating the EC Meter P110 / P50 Press the On/off button to start the meter. Press the MODE button to switch to EC on the display. Insert the meter in an upright position in calibration solution (µ5/cm 1413) EC 1.4 (make sure this is 25 'C or 77 'Fl and stir gently. Wait until the value on the display is stable. Press and hold the C/F button for 5 seconds. Then release the button. The value EC 1.4 will now blink on the display. As soon as the meter switches back to the standard mode, calibration is complete. Rinse the meter with clean water. The meter is now ready for use. When Is Calibration Required If the electrode has been replaced. If the meter was last calibrated over a month ago. If the meter is used on a regular basis. If high precision is needed.
