Milwaukee MA920B/1 Direct Measurement Food Grade pH Probe
The MA920 probe is a food grade probe for use with the MW101 or MW102 PRO pH meters. It is specifically designed for the pH analysis of semisolid foods such as processed meats, soft cheeses, soups, sauces, and sushi rice.
The open junction design reduces clogging from suspended solids and proteins found in food and dairy products for a more stable pH measurement and reduced maintenance.
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 products.
Polyvinylidene fluoride (PVDF) is a food grade plastic that is resistant to most chemicals and solvents used for disinfection in the food sector, including chlorine (bleach).
CARE AND USE
pH meters usually start performing poorly because of problems with the probe, specifically the glass sensing bulb and the reference junction. The glass bulb loses sensitivity with use and will eventually fail, which is true of all pH probes. The reference junction is a small hole that allows the meter to compare the sample to a reference. If the junction hole gets clogged, the pH probe will no longer function.
