Rail Ohmmeters

Megger DLRO10HD Heavy Duty 10A Low Resistance Ohmmeter.

Heavy duty low resistance ohmmeter combining rugged construction with accuracy and ease of use. It features an internal rechargeable battery and can also operate from a mains supply, even if the battery is completely flat.

2 high power ( up to 25W) ranges ideal for inductive applications, and where heating a potential weakness is desirable.
7 low power output ranges limited to 0.25W to avoid heating the test piece and to extend battery life.
Rechargeable battery or line power supply, continuous operation, even with dead battery.
10 A for 60 seconds, less time waiting to cool, great for charging inductance.
High input protection to 600 V, inadvertent connection to line or UPS voltage will not blow a fuse.
Heavy duty case: IP 65 lid closed, IP54 operational (battery operation only)
Large backlit LCD is clear and easy to read in all lighting conditions.
Rotary switch selects one of five test modes, including auto start on connection, giving ease of use.

DH5 straight duplex handspike set with 2.5m long leads.
