Milwaukee MA920/B1, electrode for pH meter MW101 PRO SOIL

Get total control over the pH of your soil or substrate with the professional electrode MA920B/1. It has been specially designed for direct and reliable measurements in soil where conventional electrodes fail. Forget inaccuracies caused by clogging and get data you can rely on.

Key features and benefits of the MA920B/1 pH electrode

Every detail of this probe has been designed for maximum performance and durability for measurements in demanding conditions.

• Open Junction design: a revolutionary design that effectively prevents solid particles from the soil or substrate from clogging the electrode. This ensures stable, fast and repeatably accurate measurements.
• Durable PEI body: The electrode body is made of polyetherimide (PEI), which is highly resistant to mechanical damage and aggressive chemicals. In addition, it is very easy to clean.
• Maintenance-free operation. It is always ready for use.
• Double reference electrode: This system minimizes the risk of contamination and significantly extends the lifetime and reliability of the probe compared to standard electrodes.
• Tapered tip: The sharp, tapered tip easily penetrates compacted soil or dense substrates without risk of damage.
• Universal BNC connector: The probe features a standard BNC connector so you can connect it to the vast majority of pH meters on the market.

Why choose a dedicated probe for soil measurements?

Standard laboratory pH electrodes are designed for measurements in liquids. When attempting to use them in soil, they quickly become clogged, their measurements become unstable and they are often irreversibly damaged. The MA920B/1 probe is the opposite - it is robust and its design is directly adapted to work in solid and semi-solid materials.

Investing in a dedicated electrode will not only save you time spent on constant cleaning and calibration, but also money on frequent replacement of unsuitable probes. It's a professional tool for anyone who is serious about growing.

Usability and wide compatibility

This pH electrode is ideal for a wide range of applications where you need to know the exact pH of the growing medium. It is great for:

• Direct measurement of pH in soil and soil media
• Measurements in coconut and rockwool substrates
• Checking pH in soil solutions and suspensions
• Growing annuals, herbs, tomatoes, chillies and other vegetables
• Horticulture, agriculture and nursery... and many other possibilities

With its universal BNC connector and meter cable, you can easily connect it to your existing pH meter and start measuring immediately.
