Milwaukee MA920B/1 Direct Stick Measurement pH probe for use with the MW101 or MW102 PRO pH meters.

The Milwaukee MA920B/1 grade probe is designed for the pH analysis of semi-solid foods such as processed meats, soft cheeses, soups, sauces, and sushi rice or any soil Growing media such as Coco Coir, Soil, Rockwool and other media.  It’s tough (PVDF) body and toxic free electrolyte is perfect for food or growing media.

Open Junction
The open junction design reduces clogging from suspended solids and proteins found in food and dairy products or growing media for a more stable pH measurement and reduced maintenance.

Conical Glass Tip
The conical shaped tip design allows for penetration into solids, semi solids, and emulsions for the direct measurement of pH in a variety of food or growing media products.

Polyvinylidene fluoride (PVDF) is a food grade plastic. Is resistant to most chemicals and solvents. Used for disinfection in the food sector, including chlorine (bleach).  It is also a tough material designed to hold up extremely well in all kinds of growing media applications.

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.

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.

The pH sensing bulbs become less sensitive over time so make sure that you are calibrating reguarly to keep your PRO pH meter accurate. Also, calibrate after cleaning or a long period of storage.
