La sensibilité à soufre dioxyde dommage varie entre différentes cultures et différentes variétés de la même culture. Faire les gens conscients de ce, scientifiques utilisation a certain quantité de soufre dioxyde dans le laboratoire à fumer different cultures. Après a période de temps, les dommages à differents cultures est complètement different et can être divisé en trois catégories: sensitive crops, moderately sensitive crops, crops, and resistant crops. Pour exemple, sensible cultures inclure orge, coton, soja, épinards, carottes, et piment poivrons; Moyen résistant cultures include blé, haricots, arachides, concombres, colza et tomates; résistant cultures include riz, maïs, et pommes de terre. Use a pH mètre à mesure le sol acidité et alcalinité, select approprié plantes for plantation, and make the harvest more objective.
The pH meter, abbreviated as pH meter, consiste of two parts: an electrode and an ampèremètre. It is a communly used instrument and equipment, consisting of three parts: a reference electrode, a glass electrode, and an ampèremètre. Widely used in industries, agriculture, scientific research, environmental protection, and other fields.
A pH meter is a commonly used instrument and equipment, also known as a pH meter. Mainly used for precise measurement of the pH value of liquid media, coupled with corresponding ion selective electrodes, the MV value of ion electrode potential can also be measured. CT series pH meters are widely used in industries, agriculture, scientific research, environmental protection, and other fields. This instrument is also an essential inspection equipment for QS and HACCP certification in food and drinking water plants. A pH meter is an instrument used to measure the pH value of a solution. The main body of the acidity meter is a precision potentiometer. When measuring, insert the composite electrode into the solution to be measured, and different electromotive forces will be generated due to different acidity (hydrogen ion concentration) of the solution to be measured. Amplify it through the DC amplifier, and finally point out the pH value of the solution to be measured by the reading indicator (Voltmeter). The acidity meter can be used within the pH range of 0-14.
