Abstract: A vane anemometer includes an anemometer body forming a receiving chamber that has a side wall forming retention slots for receiving and retaining therein an impeller assembly. The impeller assembly includes an upper cage forming retention tabs and coupling slots, a lower case forming coupling tabs and notches, and an impeller set rotatably supported between the upper cage and the lower case. Each coupling tab of the lower case forms a coupling pawl engageable with each coupling slot of the upper cage to couple the upper cage and the lower case together. The retention tabs of the upper cage are received in the notches of the lower case and each includes a retention nub, whereby the retention tabs form engagement with the retention slots of the receiving chamber of the anemometer body to easily mount the impeller assembly to the anemometer body in a secure manner.

Abstract: The present invention is to provide a hand-hold measuring-equipment recoding device that is mainly improvements aimed at the small sized hand-hold measuring equipment. The measuring machine body having a display, several buttons, and a sensor set in it, and is characterized in that a memory card slot is set in the machine body to provide for the insertion of the SD card. And, there are set with a microprocessor, a sensor circuit, and a memory card driver circuit in the machine body. Through these, the measured data records and measuring time are saved directly in the SD memory cards, then the SD memory cards is utilized to be inserted in the computer to read data and perform a further data analysis. Thus, it can solve the former problems of inconvenience caused by the measuring equipment must connect with the computer through a transferring cable and must proceed the measuring at the measuring site simultaneously while measuring.

Abstract: The invention relates to a vibration and rotation detector, which includes a main body with control buttons and a panel. The main body has its one end connect with a rotation probe and the other end a vibration probe that obtains double functions in one single detector. Hence, the detector can detect different environment factors more easily and efficiently.

Abstract: The invention relates to an environment detector with a four-in-one probe having functions for detecting humidity, temperature, light, and wind speed of environment. The probe includes a connecting wire and a connecting head to engage with a connecting receiver formed on the detector for electrical connection, while the probe can be placed independently in environment being detected. Hence, the data of the environment can be read from the panel of the detector easily and efficiently.

Abstract: This invention is directed to a combination touchless (photo type) and contact type tachometer having a digital display for measuring high, medium and low rotating and surface speeds. Mechanical rotation may be detected by a photo emitting-receiving sensor on the left-hand end of the device or by the contact transmitter located on the right-hand side. The received signal is amplified by an amplifier circuit and regulated by a regulator circuit. Subsequently the data is processed by a standard micro-processor IC circuit, for performing calculations, unit conversion and display decoding. The speed and other information are precisely displayed by a shiftable and reversible, rotatable 180.degree., digital displaying unit to achieve the advantages of an easy to read, precise, economical and effective tachometer.
