  • Electric Energy Test Equipment

    Kvtester Electronics Technology Co.,Ltd

    Clamp Phase Meter is special designed for voltage, current and phase tests, it is in high-precision, low price, portable hand-held, dual-channel input measuring. It's easy to measure the phase between U-U, I-I and U-I, identify the inductive circuit ,capacitive circuit and the phase sequence of three-phase voltage, detect the wiring group of transformer, test the secondary circuit and bus differential protection system, display the phase relationship among the CT groups of a differential protection system, and check if the wire of electric meter was correctly connected. When testing customers do not need cut off the tested current which input by clamp-current transformer. When measuring the phase between U1 and U2, the two input circuit loop are completely isolated, so the possible misconnection is absolutely avoided, which may result in short circuit and may even burn the meter. The monitor of the device is high-contrast LCD screen, and the character in big size, which helps to obtain the best visual effects.

  • Pointer Insulation Resistance Tester

    HT2550 - Wuhan Huatian Electric Power Automation Co., Ltd.

    With the rapid development of China's power industry, electrical equipment preventive experiment is an important part in protecting the safety operation of power system and maintenance. Insulation diagnosis is an important method to detect insulation defects or failure. Pointer insulation resistance tester is the special instrument to measure insulation resistance. JJG662-89 "insulation resistance meter (megger)" approved in May 1990 requires that insulation resistance meter is one of compulsory verification instruments. Nowadays the development trend of electrical equipment (such as transformers, generators, etc.) is that high capacity, high voltage, diversified structure and better seal. So insulation resistance meter (pointer) itself must have the characteristics such as large capacity, strong anti-interference ability, diversified measurement indexes, accurate measurement results, easy and fast measurement process, easy to carry and so on. The instrument produced by our company is equipped with ultra-thin taut suspension meter. It is an ideal tester to measure insulation resistance of these equipments such as transformer, instrument transformer, generator, HV motor, power capacitors, power cables, arrester, etc.

  • Audio Function Test Equipments

    Aplab Limited

    APLAB's Distortion & Level Meter Model 2007 are versatile instruments useful for testing audio & communication equipments. Harmonic distortion is one of many types of distortions created in audio and communication equipments. Harmonic related frequencies caused by non linear elements in amplifiers, create a poor distorted signal to the listener. Aplab's Distortion & Level Meter Model 2007 help to measure the total of this distorted frequency components present in the signal, quickly and very easily in a frequency range of 30Hz to 300KHz. Thus it is used as an ideal test equipment in electronics labs & in production test setup. It can also be used as an AC voltmeter for general purpose voltage & gain measurements over a wide range of level & frequency.

  • Digital Tank Test Kit

    4109 - M. C. Miller Company

    The voltmeter included in the kit, the “Model DPM” voltmeter, is designed for ease of use by meter readers and corrosion technicians alike and the voltmeter comes with an integrated RE-5 reference electrode attached for “metallic structure-to-soil” potential difference readings. The kit also includes a special test lead that has a brass thumb screw on one end which allows the test lead to substitute for the RE-5 reference electrode. This substitution allows the voltmeter to take “structure-to-structure” potential difference readings. The voltmeter offers two ranges, ±2VDC and ±20VDC with a 20MΩ input impedance. Since the voltmeter is digital [in contrast to the meter in our analog tank test kit (Cat. # 4108)], both negative and positive voltages are displayed. `

  • Power Cell Power Transducers for Wide Ranging AC/DC Loads

    PH-3A and PH-1000 - Powertek LLC

    You can know the load on an electric motor by measuring the electric current going to the motor (Amps). But, this is not the best way to do it since a lightly-loaded motor doesn't use the electricity very efficiently. (In technical terms, the power factor is low.)A better way to know the load is to measure the motor power. (Power is measured in Horsepower or Watts.) Motor power gives you a straight line so it works well even when the motor is lightly loaded.The Power Sensors that we make measure the motor load (Horsepower or Watts) and send a signal to meters or computers. The operator can see what the status is on the meter or, the computer can make decisions.
