Photoelectric effect tester

Abstract

The invention discloses a photoelectric effect tester. The photoelectric effect tester includes a charging indication lamp, a tester body, a switch and a voltage polarity knob; a protective shell is fixed onto the exterior of the tester body; and a voltage input interface, which is adjacent to the bottom end of a test display screen, is embedded into the front surface of the tester body. Accordingto the photoelectric effect tester of the invention, the protective shell is adopted, so that the compressive capability of the tester body can be improved, and the detector body can be prevented from being damaged by external collision; a heat-dissipating plate is adopted, so that air circulation speed can be increased through the rotation of fan blades, and therefore, a heat dissipation effectcan be improved, and the service life of the tester body can be prolonged; and a first damping spring and a first buffer plate are adopted, so that the detector body can be protected during a movementprocess, and therefore, the problem of damage to the protective shell caused by hitting due to the swing of the detector body can be solved. The photoelectric effect tester of the invention has the advantages of convenient installation, convenience in carrying and suitability for general popularization and use. According to the photoelectric effect tester, the service life of the detector body can be prolonged.

Description

technical field [0001] The invention relates to the technical field of photoelectric effect testers, in particular to a photoelectric effect tester. Background technique [0002] Photoelectric detection technology is a new detection technology produced by the combination of optics and electronics. It mainly uses electronic technology to detect optical signals, and further transmits, stores, controls, calculates and displays. In principle, photoelectric detection technology can Detect all non-electricity that can affect the amount of light and light characteristics. It can convert the non-electricity information to be detected into optical information that is easy to accept through the optical system, and then use photodetectors to convert the optical information into electricity, and further amplify through the circuit. Processing, in order to achieve the purpose of electrical signal output. [0003] However, the photoelectric effect testers currently on the market have com...
