Milwaukee MA920B/1 – Direct Stick pH Electrode for Milwaukee MW101 and MW102 PRO models
The Milwaukee MA920B/1 electrode is designed for direct pH measurement in semi-solid materials such as food products (meat, cheese, sauces, processed foods) as well as in growing media like soil, coco coir, and rockwool. It performs exceptionally well in conditions where standard laboratory electrodes struggle to deliver stable readings.
The probe features a durable PVDF (polyvinylidene fluoride) body, resistant to chemical and disinfecting agents. Its open junction design minimizes clogging caused by suspended solids or proteins, ensuring long-term measurement stability. The conical glass tip allows easy penetration into semi-solid samples, providing accurate and repeatable results even in challenging environments.
The electrode is filled with Viscolene Ag/AgCl gel, eliminating the need for electrolyte refilling and making it virtually maintenance-free. The BNC connector ensures compatibility with most pH meters, including Milwaukee MW101 and MW102 PRO models.
