• 100 measuring strips for pH test
• for EMa and liquid EM products

With these pH indicators you can easily and quickly determine the pH value of various liquids.

...

• Professional pH meter
• Solid quality
• PH value always in view
• Handy and easy to use

The MW100 pH meter from Milwaukee is a very solid and durable professional device for checking the pH value on a regular basis.
Especially in hydroponic systems, but also when growing on soil or substrates, the regular control of the pH value is of great importance.
Deviations from the ideal pH value are dangerous for the plant in both directions and lead to deficiency symptoms. Depending on the cultivation method, the ideal pH value is 5.5 to 6.8.

...

• Easy and direct measurement of the pH value
• Accurate and reliable
• For irrigation water and nutrient solution
• Good price-performance ratio

The pH600 from Milwaukee is a very easy to use meter for determining the pH value in irrigation water or nutrient solution.
Especially in hydroponic systems, but also when growing on soil or substrates, the regular control of the pH is of great importance.
Deviations from the ideal pH value are dangerous for the plant in both directions and lead to deficiency symptoms. Depending on the cultivation method, the ideal pH value is 5.5 to 6.8.

This pH meter set allows the distinguished hobby gardener uncomplicated testing of the optimal pH value of irrigation water both before and after adding fertiliser. The pH value defines how "acidic" or "alkaline" a fluid is, i.e. how well other substances can dissolve in it. As such, the fluid should have an ideal pH value so that the added nutrients can dissolve optimally, as they are otherwise inaccessible to the plant. (Roots cannot "directly" take in nutrients, only in a solution with water).

The digital pH meter ADWA AD11.
Measure pH values easily, safely, and reliably.

The electronic pH meter AD11 by ADWA enables uncomplicated testing of the optimal pH value of irrigation water both before and after adding fertiliser. The pH value defines how "acidic" or "alkaline" a fluid is, i.e. how well other substances can dissolve in it. As such, the fluid should have an ideal pH value so that the added nutrients can dissolve optimally, as they are otherwise inaccessible to the plant.

The Bluelab electronic pH meter enables uncomplicated testing of the optimal pH value of irrigation water both before and after adding fertiliser. The pH value defines how ?acidic? or ?alkaline? a fluid is, i.e. how well other substances can dissolve in it. As such, the fluid should have an ideal pH value so that the added nutrients can dissolve optimally, as they are otherwise inaccessible to the plant. (Roots cannot ?directly? take in nutrients, only in a solution with water).

The Bluelab Guardian Monitor continuously provides data on the current temperature, pH, and EC values. This little assistant therefore provides the most important information to maintain an optimal nutrient solution in the long term, which is a crucial parameter for plant growth. The Guardian Monitor can easily be mounted on a wall or suspended. All of the necessary accessories for this come as standard. This item is designed for indoor use.

The Bluelab Combo Meter is a portable pH, conductivity and temperature meter all in one. If you are experiencing problems with yellow leaves, or slow stunted growth, the Bluelab Combo Meter will soon tell you if each parameter is within the plants requirements. Adjustments can be quickly made to get your crop back on track.

The pH value defines how ?acidic? or ?alkaline? a fluid is, i.e. how well other substances can dissolve in it. As such, the fluid should have an ideal pH value so that the added nutrients can dissolve optimally, as they are otherwise inaccessible to the plant. (Roots cannot ?directly? take in nutrients, only in a solution with water). The pH value of the nutrient solution should therefore always be in the appropriate range for the plant (and adjusted with pH correction solution if necessary), so that all necessary nutrients and trace elements in the nutrient solution can be absorbed.

This kit allows you to determine the pH value of irrigation water quickly and reliably. The contents of this pH testing kit are sufficient to carry out around 500 tests.

...

The Bluelab pH Probe is a replacement pH probe (electrode) suitable for use with Bluelab products that test the pH value of a solution.

...

Combine the Bluelab Multimedia pH Meter and Bluelab LeapTM pH Probe to take fast accurate measurements in nutrient solution, soil, coco coir, rockwool, potting mix and many other media types.

...

The instrument is only as accurate as the probe is clean. Accurate readings simplify crop management and provide improved growth.

This buffer solution is an indispensable accessory for operating an electronic pH meter.? Without regular calibration, the measured pH values can sometimes differ considerably. To calibrate the pH meter, the measuring electrode is submerged in a small amount of pH-4 buffer solution, and the calibration function on the measuring device is activated.

When operating an electronic pH meter, calibration is required from time to time, because without regular calibration, the measured pH values can sometimes differ considerably. To calibrate the pH meter, the measuring electrode is submerged in a small amount of pH-7 buffer solution, and the calibration function on the measuring device is activated.

...

The electrodes of pH meters must be periodically cleaned and calibrated to prevent micro deposits that may affect or even damage the electrodes. Only clean, calibrated electrodes can deliver the right measurement results. The accuracy of the calibration depends on the quality and freshness of the calibration solution. With the Milwaukee calibration solution, you can purchase an easy-to-use, high-quality fluid that will give your meter accurate measurements.
