Handheld insulation testers aimed at electricians and maintenance teams promise reliable insulation resistance readings and basic AC/DC voltage checks for on-site diagnosis. Faster fault identification and safer sign-offs reduce downtime and uncertainty during routine inspections. Is the coczow Digital Megohmmeter PM1508 the practical choice for regular insulation testing?
⚡ At a Glance
- • Measurement Range: Measures insulation resistance up to 100GΩ with five selectable test voltages (50V, 100V, 250V, 500V, 1000V)
- • Best for: Electrical contractors, maintenance engineers and technicians performing insulation and basic voltage checks
- • Not ideal for: Users who need a full-featured benchtop multimeter or advanced electrical diagnostics
Handheld megohmmeter measures insulation resistance up to 100GΩ and offers five test voltages from 50V to 1000V. Includes PI/DAR functions, AC/DC voltage measurement, automatic discharge and meets EN61010-1 CATIII 600V safety.
Accurate detection of tiny leaks – thanks to 100GΩ insulation range
Five selectable test voltages (50V, 100V, 250V, 500V, 1000V) enable resistance readings up to 100GΩ, while automatic discharge and capacitive-load comparison reduce measurement errors.
Reliable detection of small insulation faults on transformers, motors, generators, cables and appliances helps avoid unexpected failures and supports thorough diagnostics.
Clear assessment of insulation health – with PI/DAR testing
PI (Polar Index) and DAR (Dielectric Absorption Ratio) functions supply comparative metrics that enhance interpretation of insulation condition during tests.
Better differentiation between temporary and progressive insulation issues allows maintenance teams to prioritise repairs and schedule preventive work more effectively.
Safer, site-ready testing – with EN61010-1 and CATIII 600V compliance
Compliance with EN61010-1 and CATIII 600V aligns the tester with recognised safety standards for on-site electrical measurement and live-installation work.
Measurements on live installations carry less risk and the unit's durable, easy-to-use design suits routine inspection, debugging and preventive maintenance tasks.
