Digital Iron Loss Tester Model : DW22

Digital Iron Loss Tester Dw22 is single sheet core loss tester which is useful to evaluate iron loss of electrical steel sheet CRGO, CRNO material and suitable for testing EI lamination, Motor Stamping, Fan motor stamping etc. Single sheet tester is suitable for quick & tentative idea of iron loss of sample. however for precision measurement user has to use Epstein Tester.

Digital Iron Loss Tester DW-22 is provided with a stroboscopic probe when placed on specimen, closes the magnetic path between probe and specimen. Probe has two coils primary and  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 micro-controller appropriate to specimen's data (core area and weight) gives result as watt/kg

Digital Iron Loss Tester DW-22 frequently used to measure the properties of both fully processed and semi-processed non-oriented and magnetic lamination steel sheet. It may also be used to evaluate oriented electrical steels in either they are sheared or stress-relief annealed condition.

We have invented & developed singe sheet test method in year 1995. Digital Iron Loss Tester Dw22 is fourth generation equipment with most advanced technology and having precision measuring circuit.  Moreover it comes with option to connect two size of probes. Small probe comes with equipment as standard. And big probe is optional, to achieve better accuracy in big size sample testing. As each probe requires individual calibration with meter so it is necessary to decide for one probe or two probe option at the time of order. 

Gopal electronics has built the reputation in the market on basis of transparency in sales, easy and quick service, and economic and reliable rates for repairing.

• The whole product range of Gopal Electronics comes with standard 1 years warranty.

• The time for repairing or calibration is maximum 72 hours after confirmation.

Calibration Service

We provide traceable calibration service according to ISO17025 for all of our product range. Every year you require to calibrate your instruments for your factory certification like ISO, and to maintain quality of your routine test and quality inspection.

Calibration by Gopal Electronics:

• Our reference meters and standards are traceable to NABL accredited lab or our internal standards as per ISO17025.
• We have calibration facility of 0.007% (66 ppm) energy accuracy for sinusoidal waveforms.
• As manufacturer we can change the calibration data and compensate the deviation in each measuring point. So you can get actual calibration not only the comparison report.
• General Service, replacement of minor parts can be carried out at the same time.
• Free firmware upgrade is also the part of our calibration process.
• We can provide calibration at special points which are not included in usual calibration on customer request, like calibration at 0.1 power factor.
• It takes maximum two days to complete the calibration process after the receipt of your instrument at our factory.
