Abstract: A distance measuring laser pointer has at least one laser source capable of emitting a light ray; and two optical elements, disposed in front of the at least one laser source, receiving and transferring the light ray into a first conic light beam and a set of multiple second conic light beams. The first conic light beam projects a first light pattern on a surface of a target, and the set of multiple second conic light beams project a second light pattern on the surface of the target. An intersection between the first light pattern and the second light pattern changes position depending on variation of a distance between the distance measuring laser pointer and the target to indicate the distance. The distance measuring laser pointer simultaneously indicates a diameter or length of the target when indicating the distance.

Abstract: A meter for reading measured values at remote distance comprises a meter and an image reading device. A display screen for displaying measured values is disposed on the meter. The image reading device is coupled on the meter for capturing the measured values displayed on the display screen of the meter and transmitting the image to an external display device for a user to read or store at a remote distance.

Abstract: A hook-type electric meter capable of providing a light source is provided, which includes a measurement body, having a display and a measurement shift manipulation key disposed thereon. A clip jaw is disposed at a top of the measurement body and a push handle for controlling opening/closing of the clip jaw is disposed at one side of the measurement body, such that the clip jaw forms a clip mouth for clipping a subject to be tested. The measurement body has a luminous source disposed at the top and facing the clip mouth of the clip jaw. The luminous source is connected to a power supply device in the measurement body and the push handle at one side of the measurement body respectively. Thus, when the push handle is pushed, the clip mouth of the clip jaw is driven to be opened and the luminous source is driven to emit light simultaneously, and the light rays from the luminous source are projected towards the direction of the clip mouth.

Abstract: An avometer includes a measurement main body. The measurement main body includes a rotary knob for selecting a measurement item, a display, and a navigator. The rotary knob is used for an operator to select one of a current measurement mode, a voltage measurement mode, a resistance measurement mode, and a diode measurement mode before performing an operation. The display is used for displaying information and measured data of the measurement mode selected by the rotary knob. The navigator is used for switching the information of the measurement mode, and displaying the information on the display.

Abstract: A multi-functional infrared thermometer having an infrared sensor device, a sensing device and a light-emitting diode (LED) light source is provided, wherein the infrared sensor device and the sensing device are disposed in a shell and used for measuring a temperature and an electric field state of a subject to be tested respectively; a control module is disposed in the shell and includes a power source device and a control circuit board for electrically connecting the control module to the infrared sensor device, the sensing device, and the LED light source, so as to detect the temperature and the electric field state of the subject to be tested and display detection results on a display device, and to provide an illumination.

Abstract: A separation-type avometer includes a manipulation device and a measurement main body. The manipulation device includes a selection module, a first wireless module, and a window module. The measurement main body includes a measurement module, a second wireless module, and an automatic determining and switching module. The first wireless module transmits a measurement mode selected through the selection module to the second wireless module of the measurement main body. The automatic determining and switching module switches the measurement mode of the measurement module according to the selected measurement mode. After the measurement is completed, the second wireless module transmits signal data measured by the measurement main body to the first wireless module of the manipulation device, so as to use the window module to display the signal data measured by the measurement main body.
