EC Meters (25)

For testing the pH, EC, and temperature of liquid plant nourishment, swimming pools, Jacuzzis, and ponds, the Aqua Master P110 Combination Pen pH EC Temp is the best option. This upgraded Combo Pen P110 Pro has a sleek, durable body and new software that guarantees correct measurements are read more quickly. Also, switching between parameters is made simple by its user-friendly buttons. When the Combo Pen P110 Pro is shipped, it is already calibrated and equipped with batteries, making it ready to use right away. With a range of 0°C to 50°C (32°F to 122°F) for temperature, 0.1 to 14.0 pH for pH, and 0.0 to 19.9 mS/cm for EC, this meter provides accurate readings for a variety of applications. Its resolution for temperature is 0.1 oC (1.0 oF), 0.1 mS/cm for EC, and 0.1 pH for pH. A replacement electrode that can be quickly changed out if it gets worn out or damaged is built into the meter. Simply take off the protective cover, carefully wash the electrode with distilled water, and dry it off to use the meter. Finally, immerse the meter upright into the solution up to the edge and turn it on/off by pressing the on/off button. The right value should appear on the display after a brief period of gentle stirring. The C/F button makes it simple to change the unit of measurement between Celsius and Fahrenheit, and the MODE button makes it possible to switch between pH and EC. To stop using the meter, rinse the electrode with water after usage and press the on/off button. There is no need to store our electrodes in liquid because they are made for dry storage. Three 1.5 Volt AG-13 button cell batteries, one user manual in Dutch, English, and German, and one digital Combo Pen P110 Pro are all included in the Aqua Master P110 Combo Pen pH EC Temp kit. This meter is a trustworthy and practical instrument for all your pH, EC, and temperature measurement needs with automatic temperature correction and an auto power-off option after eight minutes. For reliable readings, it also includes a calibration indication. This meter is small and portable, with measurements of 220 x 40 x 40 mm and an IP67 waterproof rating. At only 102 grams, it is light and convenient to use for extended periods of time. The Aqua Master P110 Combo Pen pH EC Temp is a necessary tool for measuring pH, EC, and temperature easily and precisely, whether you're a professional or a hobbyist.

The pH of your nutrient solution greatly affects the availability of nutrients within that solution. pH which is too high or too low can cause deficiencies in essential nutrients that plants need to grow. It can also negatively affect beneficial bacteria in your system or substrate.   The performance of a pH electrode or pH meter will change with time due to aging because as the electrode is used its coating degrades, to ensure it is working correctly, regular calibration is a must. If you are using your pH meter daily, you should calibrate it at least once a week.   To calibrate, use either VitaLink ESSENTIALS Buffer 4 or VitaLink ESSENTIALS Buffer 7. Using both of these buffer solutions will make your calibration more accurate.   The temperature of your solution will also affect the pH value. ESSENTIALS pH Meter has automatic temperature compensation. When calibrating, it is necessary that your pH meter and your calibration fluid have the same temperature. To achieve this, place them in the same room several hours prior to performing calibration.   Available in 250ml and 1L bottles.

VitaLink ESSENTIALS pH Down 250ml (81% Phosphoric Acid) is a quality adjuster necessary to control the pH of nutrient solutions. Concentrated for the professional grower.

Prolong the accuracy and lifespan of the pH probe on your pH meter with VitaLink Meter Storage solution. pH meters are expensive. They will all degrade over time, but often degrade faster due to a lack of proper maintenance. With VitaLink Meter Storage solution, keeping your pH probe in good condition and prolonging its useful lifespan is no longer a problem. The pH probe on your pH meter should always be stored in VitaLink Meter Storage solution when not in use to prevent it from drying out. Our Meter Storage solution includes foam be to cut to the size of the meter cap to assist in keeping the probe wet.

Whether you need to know the pH or temperature of coconut soil or any other moist, soft substrate or liquid, the Aqua Master S300 Pro 2 is the tool for you. This meter has a high-quality pH electrode and an advanced, long-lasting housing with straightforward controls. The unit is ready to use straight from the box because it has already been calibrated and batteries have been included. After removing the protective cover containing the storage solution from the electrode, the S300 Pro 2 meter is ready for use. Run clean water over the electrode and pat it dry with some dish toweling. To begin measuring, turn on the meter by pressing the on/off button and submerge the electrode in the substrate or liquid of interest (making sure the substrate is thoroughly wet or moist for accurate readings). After the reading has stabilized, use the HOLD button to store it. To prevent residue from accumulating on the electrode, rinse it with fresh water after each use and return it to its protective cap, which contains a solution for long-term storage. One S300 Pro 2 digital substrate pH/temperature meter and instructions are included in this set (in Dutch, English, and German). Temperature adjustment is offered between 32 and 50 degrees Fahrenheit (0 and 122 degrees Celsius), and the pH accuracy is 0.1 pH. The meter has a battery indication and auto temperature adaptation, and its 2-point auto calibration makes measuring pH levels from 4.0 to 7.0 a pleasure. The meter operates on three 1.5 V AG-13 button cell batteries (included) and shuts off after 8 minutes of inactivity to conserve power. The IP65 certification (IP67 waterproof electrodes) and calibration indication assure long life in any setting.

The Aqua Master Combo Meter P700 Pro2 is a multi-function device that may be used to test the EC, pH, and temperature of liquid plant nourishment and water in hydroponics, aquaponics, swimming pools, Jacuzzis, and ponds. Its straightforward controls make adjusting various settings a breeze. This meter is ready to use right out of the box since it has already been calibrated and the batteries have been installed. Combination Meter P700 Pro2 has upgraded software that provides faster readings of precise measurements and a sleek and durable new casing. Also, the electrode may be replaced if it ever gets old or broken. The electrode may be cleaned with distilled water and a soft cloth by removing the protective covering and washing it. To begin using the meter, turn it on by pressing the on/off switch and submerge it in the solution to its rim. Keep stirring gently and watch the screen for the right reading to emerge in a few seconds. Temperature readings in both Celsius and Fahrenheit, as well as pH and EC readings, may be changed with the push of a button. After each usage, push the on/off button and rinse the electrode with water. We advise standing your meter in its protective case filled with KCI storage solution to extend its life.

VitaLink ESSENTIALS pH Up is a quality adjuster necessary to control the pH of nutrient solutions.    Concentrated (50% Potassium Hydroxide) for the professional grower.

The EC level of your nutrient solution will influence your plants’ ability to absorb water. If the EC is too high, the roots cannot bring in water and the high concentration of ions can be toxic for the plant. If EC is too low, the plants may starve from the lack of nutrients. Some plants are more susceptible to EC values out of the optimal range than others and each species has an EC threshold – beyond which, its yield is decreased.    VitaLink ESSENTIALS CF Calibration Fluid has a concentration of CF 28 – EC 2.80 – PPM 1820 at 20˚C and is a necessary complement to your ESSENTIALS EC Meter.    Regular calibration is necessary to maintain accuracy of your EC meter. If you are using your EC meter daily, you should calibrate it at least once a week. When calibrating, it is necessary that your EC meter and your calibration fluid have the same temperature. To achieve this, place them in the same room several hours prior to performing calibration.    Available in 250ml and 1L bottles.
