Test and diagnose insulation on electrical equipment with accurate resistance and safety checks, ideal for workshop and site use. Confident troubleshooting and faster job completion for electricians and maintenance teams. Is the Ayitam Digital Megohmmeter the right choice for regular diagnostic work on transformers, motors and cables?
⚡ At a Glance
- • Insulation Range: Measures insulation resistance up to 100GΩ with selectable test voltages from 50V to 1000V and frequency measurement
- • Best for: Electricians and maintenance engineers who need reliable insulation diagnostics across motors, transformers and cables
- • Not ideal for: Users who require integrated live-line clamp or hands-free communication features
Combined megohmmeter and multimeter functions enable both high-resistance insulation testing and basic electrical checks. Safety-focused design includes auto discharge and recognised EN61010-1, CATIII 600V ratings.
More reliable insulation assessment - with PI and DAR comparative functions
PI (polarity index) and DAR (dielectric absorption ratio) functions provide comparative insulation metrics that highlight absorption and leakage behaviour during testing. These routines help reveal degradation not obvious from a single resistance reading.
Cleaner diagnostics let technicians distinguish ageing insulation from transient effects, so repair or replacement decisions are better informed. Useful for preventive maintenance on motors, transformers and switchgear.
Flexible test range - thanks to selectable voltages up to 1000V
Selectable test voltages include 50V, 100V, 250V, 500V and 1000V, covering low-voltage components through higher-voltage insulation systems. Frequency measurement and low-voltage test modes extend usability beyond simple megohm readings.
Adaptable testing removes the need for multiple instruments when switching between small cables and larger electrical machines. Suitable for site engineers who encounter a variety of electrical equipment.
Safer handling on site - with auto discharge and certified safety ratings
Auto discharge handles capacitive loads after measurement, reducing residual voltage risk before leads are removed. Safety compliance to EN61010-1 and CATIII 600V provides recognised protection standards for on-site work.
Reduced shock risk and clear safety credentials help maintain safe workflows around live panels and large capacitive systems. Confidence in safer disconnection means quicker, more secure testing.
