The invention relates to a water pH value detection device used in an outdoor experiment course, in particular to a portable and efficient water pH value detection pen used in the outdoor experiment course, and aims to provide the portable and efficient water pH value detection pen which is used in the outdoor experiment course, is low in production cost and convenient to carry and can stimulate independent hands-on abilities of students. In order to realize the technical effects, the portable and efficient water pH value detection pen used in the outdoor experiment course comprises a pen body, a baffle, a first bearing block, a second bearing block, a first spring, a water storage frame, a cylinder, a first rotary rod, a second rotary rod, a screw rod, a first nut and the like, wherein the baffle is vertically hinged and connected to the upper part of the right side surface of the pen body. According to the portable and efficient water pH value detection pen used in the outdoor experiment course, a piston moves leftwards or rightwards by screwing a first screw, so that water is sucked or sprayed for sampling.
Description
technical field [0001] The invention relates to a device for detecting the pH value of water quality in an outdoor experiment class, in particular to a portable high-efficiency detection pen for the pH value of water body in an outdoor experiment class. Background technique [0002] Water is the source of life. Human beings cannot do without water in their daily life and production activities. The quality of drinking water is closely related to human health. With the development of society and economy, the progress of science and the improvement of people's living standards, people's requirements for the quality of drinking water have been continuously improved, and the standards for drinking water quality have also been continuously developed and improved accordingly. Since the establishment of drinking water quality standards is related to many factors such as people's living habits, culture, economic conditions, scientific and technological development level, water resour...
