Maintenance: EC electrodes can develop nutrient build-up over time. To minimise build-up, always rinse the probe in fresh tap water after each use!.

EC to TDS conversion: Milwaukee EC Pen, like all conductivity meters, measures electrically charged ions in a solution and provides an absolute measure of conductivity. EC is often converted to TDS in parts per million (ppm). Different scales include the 500 scale, 650 scale and 700 scale. However, true PPM can only be determined through chemical analysis. Your mS/cm reading can be approximately converted to TDS (ppm), as shown in the examples below.

1. 2.00 mS/cm = 2000 µS/cm = 1000 ppm on the .50 factor scale
2. 2.00 mS/cm = 2000 µS/cm = 1400 ppm on the 442 scale or .70 factor scale

The best, most convenient solution for measuring the pH and temperature of your nutrient solution! Plants obtain their nutrients from minerals, but they can receive all the minerals they need only when certain conditions are right. Think of nutrients as a lock. pH is the key. A key factor affecting nutrient uptake is whether your solution is acidic or alkaline. We measure this through pH. The Bluelab pH pen also measures the temperature of the solution, as root health is vital to a successful harvest. Temperature affects the growth rate and structure of the plant, so a solution temperature of 18-22°C is recommended. The Bluelab pH pen offers a compact, quick and convenient way to manage your crop's success and ensure maximum nutrient uptake. Together with the Bluelab Conductivity Pen, you have a convenient, accurate system for ensuring optimal plant growth and health.

Measuring soil pH and temperature—the essentials of growing.

• All plants need a balanced diet of nutrients (food) to grow. However, plants can access nutrients only if the pH (potential hydrogen) of your growing medium falls within the correct range.
• Contrary to common belief, all growers should measure pH, whether growing in soil or solution. This is because pH plays an important role in making nutrients soluble so they can be absorbed by plants. If your medium is too alkaline or too acidic, your plants will not be able to obtain all the nutrients they need. Temperature is also important, as it can affect the structure and growth rate of your plants.
• Together with the Bluelab Conductivity Pen, you have a convenient, accurate system for ensuring optimal plant growth and health.

When growing hydroponically, it is essential to KNOW the strength of the nutrient solution before giving it to your plants. If conductivity readings are too low, your plants may not receive enough nutrients. If readings are too high, plants can become dehydrated. To take a measurement, simply place the probe in the solution and the reading will be indicated by the flashing lights.

You can extend the life of your pH electrode as follows:

1. Storage: The pH probe must be kept hydrated. Long periods of dry storage will harm the probe's sensitivity. Allowing the probe to dry may also cause deposits and clogging at its tip. Storing it in MA9015 storage solution or pH calibration buffers will help address both issues. Do not store in tap water or distilled water! This will damage the probe's sensitivity. The best way to store the probe is with the probe cap filled with storage solution or calibration buffer and the cap tightened to prevent leakage. It is also recommended that the electrode be stored upright to further reduce the potential for leakage.
2. Cleaning: Deposits on the probe tip from the mineral salts of the nutrient solution or from organic material can affect its sensitivity and clog it. We recommend regularly soaking your electrode in MA9016 cleaning solution.
3. Calibration: the glass tip of the pH probe becomes less sensitive over time, so make sure you calibrate regularly to keep your Milwaukee MC122 PRO pH Controller accurate. Also calibrate after cleaning or a long period of storage.

growers. pH can affect plants' uptake of nutrients and water and reduce the effectiveness of fertilisers, herbicides and pesticides. Managing conductivity helps growers determine the precise fertiliser or other plant needs. Care and use: The MW802 PRO portable 3-in-1 meter includes both a pH and

EC sensor in the integrated SE600 probe. All pH sensors have a limited lifespan, and their response time becomes longer over time. EC sensors are more robust but can still be affected by residue build-up. Both require maintenance. Proper maintenance of your probe will give you fast, accurate results for longer. Here are our four top tips. Always store with the cap filled with buffer

You can extend the life of your pH electrode as follows:

1. Storage: The pH probe must be kept hydrated. Long periods of dry storage will harm the probe's sensitivity. Allowing the probe to dry may also cause deposits and clogging at its tip. Storing it in MA9015 storage solution or pH calibration buffers will help address both issues. Do not store in tap water or distilled water! This will damage the probe's sensitivity. The best way to store the probe is with the probe cap filled with storage solution or calibration buffer and the cap tightened to prevent leakage. It is also recommended that the electrode be stored upright to further reduce the potential for leakage.
2. Cleaning: Deposits on the probe tip from the mineral salts of the nutrient solution or from organic material can affect its sensitivity and clog it. We recommend regularly soaking your electrode in MA9016 cleaning solution.
3. Calibration: the glass tip of the pH probe becomes less sensitive over time, so make sure to calibrate regularly to keep your meter accurate. Also calibrate after cleaning or a long period of storage.

Bluelab pH ProbePlus is an original replacement probe designed for the professional Bluelab pH PenPlus meter. Thanks to its replaceable design, you can easily restore the instrument's factory accuracy without replacing the entire meter. The probe measures pH and temperature, features Double Junction technology for more stable measurements, and can be replaced in seconds without tools.

Bluelab pH ProbePlus is designed as a replaceable measuring module for the Bluelab pH PenPlus and is made to provide long-term reliability and maximum accuracy when measuring pH. Rather than replacing the entire instrument after the electrode's natural wear, you only need to replace the probe. This reduces costs, minimises downtime and extends the life of your pH PenPlus.

The probe uses a Double Junction (double-junction) pH electrode, which provides more stable readings and a longer service life than standard pH electrodes. This technology reduces the risk of contamination of the reference system and ensures reliable measurements even during intensive daily use in nutrient solutions.

The built-in temperature sensor enables simultaneous measurement of pH and temperature, ensuring correct results under different operating conditions. Thanks to the screw mounting system, the probe can be replaced quickly and without tools.

The probe is supplied with a KCl silicone cap with an internal sponge, which keeps the electrode continuously hydrated during storage. With proper maintenance, regular cleaning and periodic calibration, ProbePlus delivers long-lasting, reliable performance.

⚠️ Important: pH electrodes are consumable items. Their sensitivity naturally decreases over time. Replace the probe if readings stabilise more slowly or calibration becomes difficult. With proper maintenance and storage, Bluelab pH ProbePlus provides reliable long-term performance.

💡 Urban Botaniks tip: To maximise probe life, use Bluelab pH Care Kit regularly for cleaning and calibration, and never allow the electrode to dry out. Storing it in KCl solution ensures a longer service life and consistently accurate measurements.

The MW804 MAX tester includes both a pH and an EC electrode. Both of them require maintenance.
All pH sensors have a limited lifespan and their response time becomes longer over time. EC sensors are more robust, but they too can be affected by the buildup of nutrient residues. So, do not forget to order Milwaukee electrode storage and cleaning solutions MA9015 and MA9016! They will help extend the service life of your instrument!

Here are our top five tips.

1. Always store it with the cap filled with buffer or MA9015 storage solution, and not water.
2. Clean your probe regularly by soaking it in MA9016 cleaning solution.
3. Calibrate after cleaning and/or storage before testing to correct changes in the pH and EC sensor.
4. Stir the nutrient solution gently for a faster result.
5. To minimise buildup, always rinse the probe with fresh tap water after every use!
