The Milwaukee MW102 Food pH meter has won fans worldwide with its reliability, fast, simple operation, toughness, and accuracy. The MW102 Food pH meter combines the power of the MW102 meter with the specialist capabilities of the MA920B/1 Direct Measurement Food Grade pH Probe. The Milwaukee MW102 Food pH Meter is a specialist food pH meter and probe combination specifically designed to analyze semi-solid foods such as processed meats, soft cheeses, soups, sauces, and sushi rice, and the food probe features include an open junction design that reduces clogging from suspended solids and proteins found in food and dairy products for a more stable pH measurement and reduced maintenance. The probe also has a conical-shaped tip design, allowing for penetration into solids, semi-solids, and emulsions for directly measuring pH in various food products. In addition, the body is constructed from polyvinylidene fluoride (PVDF). PVDF is a food-grade plastic resistant to most chemicals and solvents used to disinfect the food sector, including chlorine (bleach).

Care and Use

pH meters 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.

Sensing Bulb

The glass bulb loses sensitivity with use and will eventually fail. This is true of all pH probes.

Reference Junction

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 the reference. The pH electrode will no longer function if the junction hole gets clogged.

You can extend the life of your pH electrode in the following ways.

Cleaning and Storage

All pH sensors have a limited life, and response time gets longer with age. Properly maintaining your pH pen tester will give you fast, accurate results for longer. So, order the Milwaukee codes MA9015 and MA9016 at checkout time! This will help clean and condition the pH electrode before use!

Storage

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 make the junction hole clogged. Storing in pH probe storage solution MA9015 or pH calibration buffers will help address these issues. Do not store in tap water and DI water. This will damage the sensitivity of the probe. The best way to store the search is with the cap filled with storage solution or calibration buffer, which is tightened to prevent leakage. It is also recommended to store the electrode upright to reduce the potential for leakage further.

Cleaning

Residue from the sample can impact the sensitivity of the sensing bulb and clog the junction. This is especially true if the model has much organic material. We recommend regularly soaking your electrode in cleaning solution MA9016.

Calibration

The pH sensing bulbs become less sensitive over time, so ensure that you regularly calibrate to keep your PRO Plus pH meter accurate. Also, calibrate after cleaning or a long period of storage.
