UT253 Series Large Jaws Leakage Current Clamp Meters

UT253 series is specially designed for AC leakage current, current and voltage measurement, which adopts latest CT techniques and digital integration technology. It has large jaws of 80mm×80mm, which can clamp 96mm cables or flat-steel ground wires. It is fully automatic, can test one circuit of leakage current and three circuits of voltage, as well as display them on one screen simultaneously.

UT255 Series High Voltage Clamp Ammeters

UT255 series high voltage clamp ammeter connected with insulating rod can measure leakage current of high voltage circuit, on-line circuit, and judge if ZnO arresters get damp or do not work well. It also has functions as peak hold, data hold, data storage, wireless transmission. Its clamp can be easily removed from the tested wire by pressing or pulling back the insulating rod.

UT256 Series 200A True RMS Fork Meters

UT256 series are AC/DC fork meters with high reliability, high security, auto-range, and mini shape. Their appearance adopts creative design so that wires to be tested can be stuck by the jaw directly instead of after the jaw is pressed to open. They can measure AC/DC current provided with true RMS function. Flashlight on the meters is specially designed for smooth measurement under darkness. Full-range overload protection and distinctive appearance design make them to be a new-generation practical electrical measuring meter with better performance.

Slender clamp is very suitable for places full of concentrated cables (such as, electric power metering system,high-speed rail system, automobile circuit maintenance and so on). Non-contact measurement ensures operation safety. The meter has mini shape with high accuracy, stable performance and perfect functions. 

UT261 Series Phase Sequence and Motor Rotation Indicators

UT261 series are portable tools for determining 3-phase power phase sequence, missing phase indication, and motor phase rotation (UT261B). UT261A and UT261B can measure AC voltage of 40~690V and 90~600V respectively. These devices can operate in frequency range from 15~400Hz. UT261 are durable devices which can withstand impact from 2 meters' height. Test leads with protective tubing are included in optional accessories.

UT262 Series Non-Contact Phase Detectors

UT262 series adopt clamp type non-contact measuring method, which means users don’t need to get in touch with high-voltage exposed wires. It can start detection after three super-induction and high-insulation clamps clamp the exterior of the three-phase wires, which is safer, more practical, and more effective. Beside phase sequence detection, UT262 series can be also used for live wire detection, simple electrical inspection, phase identification, missing-phase judgment, and wire breaker searching. It is a perfect tool for phase sequence detection, motor mounting, and wire maintenance.
