Availability: Available on back-order Categories: , ,



The Metravi Pro 7275 10A MicroOhms Meter is used for measuring Transformer Winding Resistance; Grounding Continuity Resistance; Cable & Conductor Resistance; Contact Resistance of Switches, Connectors and Relays; Metal Riveting Resistance; Winding Resistance of Coils, Motor and Transducer; Connection Resistance between Metal Components; Welding Point Resistance; Battery Parallel Connection Resistance; Wire Length Measurement and Calculations, etc. 


  • The tester is controlled by a high-speed, single-chip microcomputer, with fast response speed, stable measurement and easy operation.
  • With two measurement modes. Automatic Mode: the test current can be automatically selected according to the load. Manual Mode: 7 gears test currents can be chosen: 10A, 1A, 100mA, 10mA, 2mA and 1mA.
  • Also equipped with a 480×854 true colour LCD touchscreen, which is clearly visible even under bright light and can be operated by using both touchscreen or panel buttons.
  • A large capacity, rechargeable, lithium battery and a waterproof case make the devices suitable for outdoor use.
  • With Bluetooth communication function, it can run test operations or enable viewing test result on a mobile phone using the free Smartphone App.
  • Additionally, the tester features USB interface and built-in monitoring software, which can communicate with the computer. 
  • The protection function is perfect and reliably protects the impact on the back EMF on the instrument, making the performance more reliable.
  • With the discharging function, automatically discharge after tests and avoid any mis-operation.
  • Converting resistance function compensates for the resistance change due to the heat generated and compensates for the temperature of the test product.
  • Alarm function: the resistance alarm value can be set.
  • Automatic shutdown: the tester automatically shuts down after 15 minutes of non-operation.
