Keysight 是德万用表质量怎么样 品牌概述：

Keysight, previously known as Agilent and then part of Hewlett-Packard (HP), is a well-established brand in the scientific and engineering instrument market, particularly in the field of handheld digital multimeters (DMMs) and other test and measurement equipment. HP, once the largest instrument manufacturer in the US during the 1970s and 1980s, shifted its focus towards computers and imaging technologies, leading to the creation of Agilent in 1998. In 2014, Agilent spun off its electronic and technology division, which became Keysight.
Keysight, alongside Fluke, is one of the top competitors in the professional-grade multimeter market. Fluke is known for its comprehensive product offerings, while Keysight targets a more specialized audience with higher precision and advanced features. Keysight's handheld multimeters, such as the 1230, 1240, 1250, and 1270 series, boast impressive accuracy, with some models like the 1252B reaching a precision of 0.025% and a maximum count of 50,000. These devices feature fast screen updates, advanced display technologies like OLED, and data recording and PC connectivity options for professional-level data analysis.
The 1252B and Fluke's 289C are considered premium models due to their top-of-the-line features, including a high refresh rate, peak hold, and digital bar graphs, which help engineers visualize changes in electrical signals. However, these features come at a premium price, typically above $4,000.
For users who prioritize ruggedness and durability, the 1240 and 1270 series are better suited, with better IP ratings (e.g., IP54 for 1270 and IP67 for 1241C and 1242C), making them suitable for working in challenging environments. The 1230 series, on the other hand, is a more affordable option for basic precision with a low impedance mode, which can be helpful in specific situations where high accuracy is critical.
In summary, Keysight (formerly Agilent) is a respected player in the test and measurement industry, particularly in the realm of high-end handheld multimeters, catering to professionals who need precision, durability, and advanced features. Their products, such as the 1250 and 1270 series, stand out in terms of accuracy, functionality, and performance, although they often come at a higher price point compared to more basic models like the 1230 series.
