When using a meter to measure either the ppm of total dissolved solids or conductivity of a liquid, it is necessary to periodically calibrate the meter using a calibration standard solution. Although the basis for testing EC of total dissolved solids is the conductivity of the solution, it is not
EC Calibrating Solution 1.413 should be used to calibrate your Digital EC Pen to ensure accurate readings for optimal growth. When using a meter to measure either the ppm of total dissolved solids or conductivity of a liquid, it is necessary to periodically calibrate the meter using a calibration standard solution.
pH Down Solution uses food grade phosphoric acid to lower the pH to the proper level. Grower’s Tip: Most tap water is in the 7.0 to 8.0 range. Hydroponic nutrients are typically acidic and, when mixed in tap water, usually drop the solution into the proper range. Note: pH Up
4.0 pH Calibrating Solution is suitable for all makes and models of pH pens and meters. 4.0 pH Calibrating Solution is easy to use! Just dip your electrode into a small amount of the buffer and adjust the meter to read 4.0. Do not reuse solution. The characteristic of a
pH Calibration Solution – 7 is used to calibrate your pH meter to ensure it maintains it’s accuracy. It is made under strict industry standards in order to give you a solution that is highly accurate and of good quality.
pH Storage Solution is used to keep pH probe moist which will maximize electrode performance and extend life of electrode. Directly after use and before a period of storage rinse your pH electrode under running water after every use. Then place a few drops of pH Storage Solution in cap
The Rapitest 3 in 1 meter is an analog instrument that allows the measurement of humidity, light and pH values. This meter gives us the information of three essential values to achieve good harvests. The humidity level of the crop, which helps us know when the crop needs water. Also
pH Testing Kit consists of a test tube for taking a sample, a reagent liquid to add to the test tube and a color chart showing the pH between 4.5 and 8, against which the color of liquid in the test tube is matched. pH should be tested after adding
