24AAYPP0073E1ZLDigital Iron Loss Tester (Model Rk-45)
Get Latest Price
RK-45 is most comfortable Instrument to test electrical steel sheet at site. Due to advance digital technology it became feasible to make it portable and light weight tool, for testing of CRGO, CRNO , CRNGO and semi process. While measuring iron loss (Watt/Kg), no need to cut standard size of sample. It is also used to find rolling direction of CRGO sheet by placing Probe on specimen and rotate to find minimum loss as rolling direction. This handy tool is very useful for manufacturers of Electrical items like Transformer, Motor, Stamping, Lamination and core.
Principle of Operation:
RK-45 is provided with a stroboscopic probe when placed on specimen closes the magnetic path between probe and specimen. Probe has two coils one is primary and second is secondary (like transformer). When power applied to primary coil and detected by secondary coil appropriate to specimen data and then measure voltage, current and power. After measured data calculated by microcontroller appropriate to specimen's data (core area and weight) and directly displayed Watt/Kg. on LCD Display.

DW-21 is most comfortable Instrument to test electrical steel sheet at site. Due to advance digital technology it became feasible to make it portable and light weight tool, for testing of CRGO, CRNO, CRNGO and semi process sheet. While measuring iron loss (Watt/Kg), standard size of 30 x 305 mm single strip to be tested, and more accuracy required more sample to average. Big size of Sample might be used for comparisons with known sample. It is also used to find rolling direction of CRGO sheet by using user mode function. This handy tool is very useful for manufacturer of Electrical items like Transformer, Motor, Stamping, Lamination and Core.
Operation Theory:-
DW-21 is provided with a stroboscopic probe when placed on specimen closes the magnetic path between probe and specimen. Probe has two coils one is primary and second is secondary (like transformer). When power applied to primary coil and detected by secondary coil appropriate to specimen data and measure voltage, current and power. Then measured data calculated by microcontroller appropriate to specimen's data (core area and weight) and directly displayed on LCD Watt/Kg and Watt/lb.
Three modes are provided weight mode, dimension mode, and user mode. User have to set the input data and then press start key. Display will appear watt/kg and watt/lb simultaneously.

Digital Epstein Tester (Model Ep-350)
Get Latest Price
EP-350 is designed to achieve hassle free operation in single unit, for measurement of AC Magnetic Properties of flat rolled magnetic materials, at high frequency by using Wattmeter, Ammeter, Voltmeter and source. This test method is a fundamental method for evaluating the magnetic performance of flat-rolled magnetic materials in either as sheared or stress relief annealed condition. This test method is suitable for design, specification acceptance, service evaluation, and research and development.
EP-350 has digital controlled crystal accurate 16 Bit sine wave Generator, which provides 25 Hz to 450 Hz harmonics free non distorted power for testing of specimen. It has built in required (digital sampling) measuring meter, as Flux Voltmeter, RMS Voltmeter, RMS Ammeter, Peak Ammeter, Wattmeter and Power Factor meter. These measuring devices are (temper proof) precisely calibrated to achieve high accuracy and long term stability. Accuracy and stability of EP-350 is better than specified in national and international standards. (Reference to ASTM: 343, IEC: 60404-2, BIS: 649)

3-Phase Precision Power Meter (Model Pa-600)
Get Latest Price
PA-600 is a state of art & technology developed by Gopal Electronics, as a result of continuous & steady research and development of our qualified engineering staff.
PA-600 is powerful Instrument for testing Single Phase and Three Phase AC Machines due to it’s high sampling rate, simultaneous measurements for all channels, and capability to perform accurate measurements of Active Power, Trms Value, Mean value and Peak value of Voltage and Current. PA-600 is Micro-Controller based Instrument and hence, performs accurate calculations of PF, CF, FF, S, Q, with any load and signals of frequencies from 30 Hz to 800 Hz. Isolated inputs have a high immunity against electrical disturbances, high dynamic common-mode rejection and feature of measuring range. Current directly from 80mA to 80A and for voltage directly from 6V to 600V.
Application of PA-600:-
PA-600 is very useful to test and measure single phase/three phase AC Machines like Transformer, Motor, Food processor, Air conditioner, Fan, Heater, Lighting Ballast, Energy meter, calibration of AC meters etc.
