摘要： An infrared thermometer measures a temperature of an energy zone. The infrared thermometer comprises a beam splitter for splitting an incident light beam from an energy zone into an infrared light beam and a visible light beam; an infrared detector for detecting the infrared light beam and generating a signal indicative of a temperature of the energy zone according to the detected infrared light beam; and a sighting device having an optical module for generating a reflective reticle image and transmitting the visible light beam to generate a target image at a sight window, wherein the sighting device is configured to superimpose the reflective reticle image over the target image at the sight window to align the infrared detector with the energy zone. The infrared thermometer and an associated measurement method facilitate the alignment of the energy zone by the users, thereby improving the accuracy of the measurement.

摘要： The present application relates to a clamp meter and a clamp probe that can be matched for use with the clamp meter. The clamp meter comprises a main meter body having an interfacing connector and one or more clamp probes, wherein each of the clamp probes is detachably connectable to the interfacing connector of the main meter body. Each of the clamp probes has a converting unit that converts a signal measured by the clamp probe to an output measurement signal within a predetermined measurement range of the main meter body, and each of the clamp probes has an identity indicator readable by the main meter body. As the clamp meter according to the present application can be matched with a plurality of clamp probes having different measurement ranges, a user only needs to purchase one main meter body and one or more clamp probes of different models to meet various measuring needs. This can enhance the flexibility and extendibility of the usage of a clamp meter, as well as reduce the user's financial burden.
