Megger MIT310A-EN MIT 310A EN Insulation Resistance Continuity Tester

The Megger MIT310A-EN features a digital / analog arc moving coil display to produce the feel of a real analog test instrument. 

The MIT310A EN is rugged enough to handle harsh working conditions with its protective rubber casing and rigid foldable display cover. Easily accessed functions along with color coded ranges help you to reduce your testing durations, while a convenient user guide located inside the lid gives you the basic required information. Comfortably hang the MIT310A EN around your neck to keep your hands free while working, and easily read the large 20 millimeter high character display.
 
Applications
Megger's MIT300 series insulation resistance testers can be utilized in many aspects of industrial, commercial and domestic electrical contracting, testing, building maintenance, servicing and inspection. Combining Insulation testing with continuity testing, the MIT310A-EN caters to all characteristics for fixed wiring installation as well as  
  • Motor, power tool, switchgear and generator testing
  • Panel building
  • Low-volume manufacturing
  • Street lighting
MIT310A EN Includes
  • 6220-779 -- Set of test leads & crocodile clips
  • 3 year warranty
 

Megger MIT310A EN Features
  • Continuity & buzzer tests start automatically when connected to circuit
  • Insulation Test Voltages - 1000, 500, 250 Volts DC
  • Resistance measurement range 10 Ohms - 2 kOhms
  • Intelligent Safety System
    • Safety Interlock prevents unsafe test lead connections
    • Safe contact detector Even when the MIT300 EN connects with live circuits when on the continuity setting it will be safe and undamaged
    • Live voltage alert warns you when circuit voltage is above 25 Volts
    • Safety lockout feature prevents your test from executing if circuit voltages are above 50 Volts
    • Continuity check feature prevents continuity tests or buzzer tests on live circuits
  • Meets or exceeds International Wiring Regulations including BS7671 & VDE 0413 pts. 1 & 4, NFC15-100, IEC 364, HD 384, ES59009, EN 61557 and NEN3140
