Properly maintaining your pH Tester will give you fast, accurate results for longer.Here are our top four tips. 1. Always store with the cap full of buffer or storage solution MA9015 not water.2. Clean your Tester regularly by soaking in cleaning solution MA9016.3. Calibrate after cleaning and/or storage before testing to adjust for changes in the pH sensor.4. Gently stir the Tester in the sample for a faster result.

MA9015 is a lab grade electrode storage solution prepared with premium chemicals to improve the performance and extend the life of your pH and ORP electrodes, testers and pens.To ensure a quick response and free-flowing liquid junction, the sensing element and reference junction must not be allowed to dry out. Properly storing your pH electrode in a solution keeps the glass membrane well hydrated which maintains proper function and provides accurate readings.MA9015 also helps keep the junction in your pH and ORP electrode flowing which is critical for fast results.DESIGN FEATURESFundamental for the correct use of electrodes and for obtaining the most accurate and reproducible readings.Formulated to minimize organic growth on your electrode.Sealed against light with air tight, tamper proof cap.Factory blended to precise standards in a dedicated, temperature controlled environment.Simply open and add to the cap of your electrode or tester.USE:Replace when it gets dirty or evaporates. It must be always filled up till the mark on cap of the pH-meter.

Cleaning solution is ideal for cleaning all pH, ORP and TDS meter's probes. To help maintain high performance and accuracy for any electrode, regular cleaning is required to remove the build up of dirt and setiment on the glass or carbon surfaces of a sensing probe. Use M10016B to help extend the life of the meter's electrode. Electrode cleaning solution should not be a substitute for rinse and or storage solutions. Sachet packaging means that you get fresh solution every time. Ideal for infrequent or field use. No risk of using an expired calibration solution. Milwaukee cleaning solutions are designed to help you achieve reliable and repeatable measurements while extending the life of your electrode.DESIGN FEATURESFundamental for gently cleaning the electrode between uses and before storage.Sealed against light and air.Ideal for on-the-spot cleaning too.Simply open, insert the tester or electrode into the sachet and gently stir let soak for 15 minutes.
