Model: TRM200
Turns Ratio Meter
Turns Ratio Meter Model TRM200 is widely used in transformer industry in manufacturing and repairing service. It directly display the ratio of LT turns & HT turns. It is capable to measure turns ratio till 1:1200. Turns ratio meter is designed to be a rugged and reliable. It is equipped with stable 250mA source. The design is based upon in-house invented & patented technology. TRM200 has also option for 1amp current source on demand.
Turns Ratio Meter TRM200 is completely new approach in technology. It detect HT / LT connection and hense prevent the equipment in case of wrong connection. It applies 36 volt on HT winding side of transformer and measure back through the LT side of the transformer. And directly gives result of Turns Ratio, Polarity, Voltage & current on display. 3Nos of key provided Fast key for fast measurement. Accurate key for accurate and precise measurement and LYCT key for LV testing which is very much use full for primary inspection of the transformer.
Turns Ratio Meter gives quick results within 2-3 seconds in fast mode. In Accurate mode it applies mathematical filters and gives accurate results. Low Voltage measurement helps when you want to check short-winding or test the CT.
There is No need of calibration due to the utilization of high precision components in the design. Turns Ratio Meter TRM200 is provided with 5meter standard connection leads for easy and quick connection. Basic accuracy of internal measurement is 0.1%
Warranty
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 3 years warranty.
- For easy warranty claim, you can register your product on our website in case you purchased from any dealer.

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.
