Advanced clamp technology for fast and accurate earth testing
Product Overview
Uni-T UT278B & C & D Series Ground Pile Clamp Earth Resistance Tester Price in Bangladesh
UNI-T UT278B, UT278C, and UT278D Series Ground Pile Clamp Earth Resistance Testers are advanced professional instruments designed for fast, non-intrusive grounding measurement, and the keyword Uni-T UT278B & C & D Series Ground Pile Clamp Earth Resistance Tester Price in Bangladesh is commonly searched by electrical engineers, utility maintenance teams, and industrial technicians who need efficient earth resistance and soil analysis tools.
These models use clamp-based measurement technology, allowing users to test grounding systems without disconnecting cables or using auxiliary earth rods. This makes field testing significantly faster and safer compared to traditional 3-point methods. The UT278 series is widely used in power distribution networks, substations, telecom sites, and industrial grounding systems.
The series offers multiple advanced functions including earth resistance measurement, leakage current measurement, grounding voltage detection, and soil resistivity testing (UT278C & UT278D models). It also supports 3-wire and 4-wire measurement modes for more detailed analysis of grounding performance.
For usability, the UT278 series features a 2.4-inch color LCD display, USB data transfer, alarm function, and built-in data storage, making it suitable for documentation and professional reporting. The device also includes anti-interference filtering technology to ensure stable readings in noisy electrical environments.
The design is rugged and field-ready with a rechargeable lithium battery, large jaw opening (around 68 mm), and durable construction for industrial use. It is engineered for long-term reliability in harsh working conditions such as outdoor substations and factory grounding systems.
Regarding pricing in Bangladesh, the UNI-T UT278B/C/D series falls into the high-end industrial testing category, and the price varies depending on model (B, C, or D), importer, warranty, and availability. UT278D is typically the most advanced and expensive among the three due to additional soil resistivity and higher measurement capability.
Overall, the UNI-T UT278 series stands out as a modern and efficient solution for earth resistance testing. Its clamp technology, multi-function measurement capability, and strong data handling features make it an essential tool for professionals focused on electrical safety and grounding system performance.
