It isequipped with powerful measurement and data processing software, which can help complete measurements, calculations and displays of voltage, current, activepower, power factor, phase angle, apparent power, reactive power, power,frequency, temperature and other parameters.


UT240

UT240 series is a stable, safe and reliable handheld power and harmonics clamp meter, which combines with digital ammeter,power measurement, harmonic measurement and equipped with a powerful measurement and data processing software. It is suitable for testing,calculating, displaying voltage, current, active power, power factor, phase angle, apparent power, reactive power, harmonic analysis and test, electrical energy, frequency etc. Its harmonic measurement can be measured to 20 times.


UT251

UT251 series high-accuracy and high-sensitivity leakage current clamp meter is specially designed for testing AC leakage current. It is designed by the latest CT technology and digital integration technology, with small size, high precision and perfect function.It is suitable for electricity, communications, meteorology, railways, oilfields and construction measurement, research and teaching units, as well as industrial and mining enterprises etc. Its sensing core is made of specialalloy, using magnetic shielding technology, which almost unaffected by the external magnetic field and to ensure high accuracy, high stability and high reliability of perennial constant measurement.


UT253

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

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

UT256 series is an AC/DC fork meter with high reliability, high security, auto-range, and mini shape. Its 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. It can measure AC/DC current provided with true RMS function. Flashlight on the meter is specially designed for smooth measurement under darkness. Full-range overload protection and distinctive appearance design make it be a new-generation practical electrical measuring meter with better performance. 


UT257

UT257A is well designed for AC leakage current and current measurement. It adopts latest CT techniques and digital integration technology. It has the largest jaw and highest current range in the world so far. The large jaw(108mm×148mm), which can clamp φ108mm electric cables or 160mm×4mm flat-steel ground wires, is particularly suitable for cable leakage and transformer ground flat steel leakage detection. The meter is fully automatic and displays on LCD.


UT258

UT258A is well designed for on-line measurements of DC/AC leakage current and current below 600V, which adopts latest CT and digital integration technology. 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. 


UT262

UT262 series adopts clamp typenon-contact measuring method, which means user doesn’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 wires maintenance.
