Megger Insulation Resistance Tester, 250 V Min, 5 kV Max, 20 TΩ CAT IV

Robust and accurate insulation testing for motors, transformers, switchgear and cables. The Megger Essential range is designed for engineers who need reliable go/no-go insulation testing without the complexity of onboard storage or Advanced diagnostics. Available in 5 kV (MIT515/2) and 10 kV (MIT1015) models, both testers include Megger's patented technologies to help you work Faster and safer in the field.

Best for: Industrial maintenance engineers, utilities, electrical contractors and OEMs carrying out routine insulation testing on electrical assets.

Patented PI Predictor™ – Reduces Polarisation Index test time by up to 50%, helping you test more assets in less time.

Patented Re>Act™ technology – Monitors reabsorption current to show when insulation is safe to retest, improving accuracy and reducing the risk of dangerous return voltages.

Stable results in noisy environments – 3 mA noise immunity delivers dependable measurements in typical industrial and distribution applications.

Built for the field – IP65-rated case (lid closed), CAT IV 600 V safety rating, live circuit detection and locking test leads for safe, rugged operation.

Both models offer the same core features and test modes (IR, DAR and PI)
