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

Product detailed description

Gain complete control over the pH of your soil or substrate with the professional MA920B/1 electrode. It was specially designed for direct and reliable measurement in soil, where standard 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 with maximum performance and long service life in mind when measuring in demanding conditions.

• Open Junction design: A revolutionary design that effectively prevents the electrode from clogging with solid particles from soil or substrate. This ensures stable, fast and repeatably accurate measurement.
• Durable PEI body: The electrode body is made of polyetherimide (PEI), which is highly resistant to mechanical damage and aggressive chemicals. It is also very easy to clean.
• Maintenance-free operation: Thanks to the gel electrolyte fill, you do not need to top up the probe or worry about maintenance. It is always ready for use.
• Double reference electrode: This system minimises the risk of contamination and significantly extends the service life and reliability of the probe compared with standard electrodes.
• Conical tip shape: The sharp, cone-shaped tip easily penetrates compacted soil or dense substrates without the risk of damage.
• Universal BNC connector: The probe is fitted with a standard BNC connector, so you can connect it to the vast majority of pH metres on the market.

Why choose a specialised probe for soil measurement?

Standard laboratory pH electrodes are designed for measurement in liquids. When used in soil, they quickly clog, their readings become unstable and they are often irreparably damaged. The MA920B/1 probe is the exact opposite – it is robust and its design is directly adapted for work in solid and semi-solid materials.

Investing in a specialised electrode will save you not only the time spent on constant cleaning and calibration, but also the money spent on frequent replacement of unsuitable probes. It is a professional tool for anyone who takes cultivation seriously.

Use and broad compatibility

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

• Direct pH measurement in soil and soil substrates
• Measurement in coconut substrates and rockwool
• Checking pH in soil solutions and suspensions
• Growing annual plants, herbs, tomatoes, chilli peppers and other vegetables
• Horticulture, agriculture and nursery production... and many other possibilities

Thanks to the universal BNC connector and the 1 m cable, you can easily connect it to your existing pH metre and start measuring immediately.
