Nutrient solution PH value, EC value and temperature combined instrument

Abstract

The invention relates to the technical field of nutrient solution detection and relates to a nutrient solution PH value, EC value and temperature combined instrument. The nutrient solution PH value, EC value and temperature combined instrument comprises a box body, the bottom of the inner wall of the box body is movably sleeved with a machine shell, a single-chip microcomputer and a storage battery are fixedly installed in the machine shell through bolts, and an alarm is fixedly installed at the top of the outer wall of the machine shell through bolts. The defects in the prior art are overcome, the temperature in a nutrient solution can be detected through a temperature sensor, the PH value in the nutrient solution can be detected through a PH sensor, the concentration of the nutrient solution can be detected through an EC sensor; and detection information is transmitted to the single-chip microcomputer, the single-chip microcomputer judges the information according to internal programming; when a certain detection value in the nutrient solution exceeds a normal range, an alarm can be given through the alarm to remind people of adding corresponding raw materials in time to adjust the interior of the nutrient solution, so that the PH value, the EC value and the temperature of the nutrient solution can be maintained in the normal range, and the emergence rate, the strong seedling rate and the seedling rate of tobacco seedlings are indirectly increased.

Description

technical field [0001] The invention relates to the technical field of nutrient solution detection, in particular to a three-in-one instrument for PH value, EC value and temperature of nutrient solution. Background technique [0002] The nutrient solution is a new type of nutrient solution synthesized by using the environmental biological ecological symbiosis technology and the principle of mycorrhizal symbiosis through biological fermentation, chemical chelation, physical activation and other processes. Nutrient solution is the key to soilless cultivation, and different crops require different nutrient solution formulations. Among them, the concentration, pH value and temperature of the nutrient solution are extremely important to the crops. [0003] The salt compounds in the nutrient solution are generally strong electrolytes and have electrical conductivity. Within a certain range, the salt content of the nutrient solution is proportional to the conductivity, that is, t...
