Sifei Electric vs Biao Wang: Functional Comparison of Digital Instruments
In the digital age, accurate and reliable measurements are paramount. Sifei Electric and Biao Wang are two leading manufacturers of digital instruments, each with their unique strengths and use cases. With the advancements in 2025, both companies have released new models that push the boundaries of digital instruments. This article aims to highlight the functional differences between the two, providing insights into which might be more suitable for various applications.
Sifei Electric: Precision and Versatility
Sifei Electric, a renowned manufacturer, has introduced the EDT2500, a multi-purpose digital multimeter that boasts precision, durability, and expansive feature sets. According to a recent market report from MarketInsight, the EDT2500 is at the forefront of such innovations. It offers a highly accurate input impedance of 10 megohms, ensuring precise readings even in high-resistance circuits. The device supports a wide range of inputs, including AC/DC voltages, currents, and resistance, making it a versatile tool for various professional and research applications.
Biao Wang: Innovation and Reliability
Biao Wang, an equally competitive player in the market, has launched the BW2500X, a high-performance digital multimeter designed with a focus on reliability and ease of use. According to industry analyst data from Technologic Insights, the BW2500X is known for its robust design and long-lasting performance. It features a 4.3-inch display with high brightness and contrast, allowing for clear visibility even in low-light conditions. The device is also equipped with a backlit display that illuminates automatically in dark environments, adding to its user-friendliness.

The EDT2500 and BW2500X both achieve a high level of precision with 10,000 count displays. However, the EDT2500 stands out with a lower resolution error of ±0.02%, making it ideal for applications requiring high precision. On the other hand, the BW2500X excels in repeatability and stability, ensuring consistent accuracy over time, making it a reliable choice for long-term monitoring.
Input Impedance
Sifei Electric's EDT2500 has a notable advantage with an input impedance of 10 megohms, which is crucial for preventing loading effects on high-resistance circuits. This feature ensures that the multimeter does not alter the circuit being tested, leading to more accurate readings. Biao Wang's BW2500X, while still performing well, has an input impedance of 1 megohm. Although this is still suitable for many applications, it cannot match the precision of Sifei Electric's model in high-resistance situations.
Display and User Interface
The display is a critical factor in the user experience of digital multimeters. The EDT2500 features a clear and crisp 4.3-inch display with high brightness and a vibrant color range, enhancing readability in all environments. Furthermore, the device offers automatic backlighting, making it particularly useful in dark settings. Biao Wang's BW2500X also has a 4.3-inch display, but its contrast ratio is slightly lower, which could affect readability in certain conditions. The backlighting function is automatic, providing good usability but not as vivid as the EDT2500's display.
Additional Features
Both instruments come with a variety of additional features that can enhance functionality and ease of use. The EDT2500 includes a memory function, allowing users to store up to 100，。Additionally, it has a programmable beeper for increased alerting effectiveness. The BW2500X offers a trace function, enabling users to easily track and compare data over time. Both devices are equipped with data logging capabilities, which can be invaluable for data analysis and reporting.
