M500 Megohmmeter for Insulation Testing，Compatible with Supco M500 Electronic Megohmmeter up to 1000 Megohms

M500 Insulation Tester – Professional-Grade Megohmmeter for Accurate Insulation Testing ✅ RELIABLE INSULATION MONITORING | ✅ EASY OPERATION | ✅ INDUSTRIAL-DURABILITY WHY CHOOSE THE M500 MEGOHMMETER? Perfect Fit for Service and Maintenance Tailored for hermetic refrigeration compressors, motors, appliances, panel boards, and relay circuits. Plug-and-Play Setup: Install 2 "C" batteries (not included), connect test leads, and start testing in minutes – no complex calibration needed. Expert-Grade Insights: Track insulation health over time to catch deterioration early (critical for hermetic motors operating in oil/refrigerant environments). Smart Diagnostic Features - Full-Range Testing: Measures insulation values up to 1000 megohms at 500 volts – covers all standard service needs. - Zone Scale Indication: Instantly assess insulation condition (e.g., <50 megohms = deteriorating insulation/contaminated refrigerant). - Overload Warnings: Detects signs of severe motor overload (via dropping megohm readings) to prevent future failures. Industrial-Grade Durability - Rugged Construction: High-impact thermoplastic case protects against drops and job-site wear. - Long-Lasting Performance: Battery-powered (2 "C" batteries) with test leads that store neatly in the case. - Pre-Tested Reliability: Factory-verified accuracy – ready for consistent use in HVAC, appliance, and electrical maintenance. Compatible With: - Hermetic refrigeration/AC compressors - Motors and household appliances - Panel boards and relay control circuits Expert Support and Guarantee ✅ PRE-TESTED PERFORMANCE: 100% verified before shipping. ✅ EASY OPERATION: Most tests take <10 minutes (even for first-time users). ✅ FREE EXPERT GUIDANCE: Clear instructions included for proper testing (e.g., terminal-to-case measurements). ✅ DURABLE CARRY CASE: Zippered vinyl case included for secure storage/transport. Note: Verify testing compatibility with your equipment; always disconnect power before testing. Professional use recommended for complex electrical systems.
