Milliohm Tester DLRO10HD

Digital low resistance milliohm tester 10 A DLRO10HD

The DLRO10HD milliohm meter combines maximum simplicity of operation with a robust IP65 case designed for stable operation on land or bench. The unit is powered either by its rechargeable battery or from the mains, making it suitable for continuous testing in manufacturing line environments/repetitive use. The rotary switch controls are simple and easy to operate in all weather conditions and with gloved hands. A large, clear, backlit LCD display is easy to read from a distance. The DLRO10HD milliohm meter provides significantly improved compliance and is capable of supplying 10 A to loads of up to 250 mΩ and 1 A to loads of up to 2.5 ≈. The duration of each test can be up to 60 seconds. The DLRO10HD milliohm meter has CAT III 300 V capability. A test lead set is available to meet the application. The DLRO10HD milliohm meter provides five test modes, each selected via a simple rotary switch.

- Sturdy transport case with shoulder strap and bag for the cable set

- The removable cover allows easy connection of test cables

- Ingress protection operation IP 54 ensures protection of elements

- 7Ah lead-acid battery provides extended operation and can be charged 

  while operating from the network

- Rotary mode switch with bidirectional modes (current inversion average 

  the result and cancels thermal EMF), unidirectional, automatic, continuous, and inductive

- Large, clear LCD display with backlighting and contrast adjustment 

- Auto-off function conserves battery.
