UT276A/UT278A Clamp Earth Ground Tester
Smart clamp testing for fast and reliable grounding checks
Product Overview
UT276A/UT278A Clamp Earth Ground Tester Price in Bangladesh
UNI-T UT276A and UT278A Clamp Earth Ground Testers are professional non-intrusive grounding measurement devices designed for fast and accurate earth resistance testing, and the keyword UT276A/UT278A Clamp Earth Ground Tester Price in Bangladesh is commonly searched by electrical engineers, technicians, and industrial professionals who need efficient grounding diagnostics without disconnecting systems.
These clamp testers use advanced non-contact measurement technology, allowing users to test grounding systems without disconnecting ground conductors or using auxiliary electrodes. This makes them highly suitable for live systems, saving time and improving safety during field operations.
Both models provide high-precision resistance measurement starting from very low values, ensuring reliable readings for professional applications. They are widely used in power distribution systems, telecom networks, lightning protection systems, and industrial electrical maintenance.
The UT276A focuses mainly on earth resistance measurement, offering stable performance with features like auto range, data hold, alarm indication, and interference signal recognition. It is a practical solution for technicians who need quick and straightforward grounding checks.
On the other hand, the UT278A provides additional functionality by supporting leakage current measurement along with resistance testing. This makes it more suitable for advanced diagnostics where monitoring current flow in grounding systems is important. It also features dual display capability for resistance and current values, improving analysis efficiency.
Both models are built with a rugged double-insulation design, making them durable for outdoor and industrial environments. Their clamp structure allows easy operation around conductors, while features like data storage, LCD backlight, and audible alarms enhance usability during field work.
In Bangladesh, the UT276A and UT278A are considered mid to high-range professional clamp earth testers, and pricing may vary depending on supplier, warranty, and availability. These devices are typically available through specialized electrical equipment distributors rather than standard retail outlets.
Overall, the UNI-T UT276A and UT278A stand out as reliable and efficient grounding testing solutions. Their combination of clamp-based measurement, strong accuracy, and rugged design makes them ideal for professionals focused on electrical safety and system performance.
