PDRM-10A Ohmmeter

PDRM-10A Ohmmeter

Ohmmeter / PDRM-10A Ohmmeter for resistance measurement from 0,01µΩ to 200 Ω.

The PDRM-10 A ohmmeter, with a range of 0.01µΩ to 200 Ω is currently the most accurate and highest resolution ohmmeter on the market, and at only 860 g it is also the lightest and most compact. All this has made it the standard low resistance ohmmeter in many electrical companies, industries and assembly companies. It has a resolution of 0.01µΩ.

Robust design, high resistance to shock and even rain make the PDRM-100 suitable for multiple applications.

Applications

  • Quality control of castings
  • Control of joints and arc welding
  • Exothermic welding control
  • Electrode control in aluminium plants
  • Inspection of contacts, switches and fuses

Advantages of the PDRM-10A

  • Much lighter and more portable than any other equipment in its class
  • Robust, suitable for laboratory and field work
  • LCD display with backlight
  • Possibility of injecting low currents for small contact measurement applications
  • A wide variety of clamps or measuring electrodes are available

Operation

The PDRM-10A uses the four-wire resistance method (also called the Kelvin method) which involves injecting current with two wires connected at the ends of the resistance being measured. The voltage drop is measured with a separate circuit and so that the voltage electrodes are on the inside of the current electrodes. The method eliminates the influence of the resistance of the measurement cables. The equipment has a small microprocessor that eliminates the influence of thermocouples and parasitic voltages and filters that allow its use even in the presence of very strong magnetic fields.
