Milwaukee MI556-001 Calibration Standard TA for MI456 Mini Titrator (100 mL bottle)
The Milwaukee MI456 PRO Mini-Titrator makes the measurement of Total Titratable Acidity simple. The MI456 PRO uses a neutralization reaction - the reaction between the acids found in wine and a base. This type of reaction forms the basis of titration methods of analysing acids. Titratable acidity is measured on a degassed sample at the end-point of 8.20 for Australian requirements and 7.00 to fulfil the requirements of the European Union. Both results are expressed as g/L tartaric acid. The MI456 PRO Mini-Titrator automatically dispenses the titrant, determines the endpoint, and completes the calculations in a fraction of the time needed for a manual titration. The MI456 PRO Mini-Titrator uses a preprogrammed method and lab grade pH electrode combined with an algorithm to determine the end of the titration reaction.
The Milwaukee MI456 PRO TA Mini Titrator is preferred by wine makers seeking results faster with lower costs and simple operation.
The Milwaukee PRO TA Mini Titrator offers:
The MI456 PRO Mini Titrator is accurate to 5% of the reading with a resolution of 0.1 g/L with a range of 0.0 to 25.0 g/L of tartaric acid. The titrator uses piston-driven pump for accurate dynamic dosing, a built-in magnetic stirrer for a faster reaction and lab grade pH electrode.
The MI456 PRO Mini-Titrator is designed to for simple one button operation with pre-standardized titrant and pre-measured reagents for easy set up.
The MI456 PRO Mini-Titrator uses a precision piston style dosing pump that dynamically adjusts the dosing volume as the voltage changes. With the MI456 PRO Mini-Titrator, you get a faster result with no need for manual intervention or calculation.
pH electrodes usually start performing poorly because of problems with the probe. The two parts of the pH probe that cause problems are the glass sensing bulb and the reference junction.
The glass bulb loses sensitivity with use and will eventually fail. This is true of all pH probes.
The reference junction is a small hole that allows the meter to compare the sample to a reference. The reading is generated based on the electrical difference between the sample and reference. If the junction hole gets clogged, the pH electrode will no longer function.
You can extend the life of your pH electrode in the following ways.
All pH sensors have a limited life and response time gets longer with age. Properly maintaining your pH electrode will give you fast, accurate results for longer. So, be sure to order the Milwaukee Maitenance Kit code PH-Main at checkout time! This will be needed to help clean and condition the pH electrode before use!
To minimize clogging the pH probe needs to be kept hydrated. Long periods of dry storage will damage the sensitivity of the probe. Allowing the probe to dry out may also result in the junction hole getting clogged.
Storing in pH probe storage solution MA9015 or pH calibration buffers will help address both these issues. Do not store in tap water or DI water. This will damage the sensitivity of the probe.
The best way to store the probe is with the probe's cap filled with storage solution or calibration buffer and the cap tightened to prevent leakage. It is also recommended that to store the electrode upright to further reduce the potential for leakage.
Residue from the sample can impact the sensitivity of the sensing bulb and clog the junction. This is especially true if the sample has a lot of organic material. We recommend regularly soaking your electrode in cleaning solution MA9016. Also:
1. Inspect the electotrode for damage or scratches, if present replace the electrode.
2. Inspect the cable. The connection cable and insulation must be intact.
3. Connectors should be clean and dry.
4. Rinse off salt deposits with water or DI water.
The pH sensing bulbs become less sensitive over time so make sure that you are calibrating regularly to keep your MI456 Mini-Titrator readings accurate. Also, calibrate after cleaning or a long period of storage.
Thank you for considering Milwaukee to help you take your results to the next level.
