The Scientific SME1202A is a high-end insulation resistance meter engineered for R&D labs, quality assurance, and production lines. Capable of outputting up to 1000V DC, this instrument measures resistance from 100kΩ up to 10TΩ (10,000GΩ) while simultaneously displaying leakage current with picoamp (pA) resolution .
Unlike basic hand-held megohmmeters, the SME1202A offers laboratory-grade accuracy and programmable features for automated testing environments.
Key Features & Benefits
- Wide Test Voltage (1V – 1000V): Programmable output allows you to test components according to various safety standards (UL, IEC) by stepping voltage from 1V to 1000V .
- Massive Resistance Range: Measures insulation resistance from 100kΩ up to 10 TΩ, suitable for high-impedance materials and multi-conductor cables .
- Dual Display: Simultaneously shows Insulation Resistance (R) and Leakage Current (I) – no need for manual calculations .
- Ultra-Fast Testing: Speeds as fast as 30ms (Fast mode) allow for high-throughput production line integration .
- Capacitive Component Safety: Features Contact Detection to safely charge/discharge capacitive DUTs (Devices Under Test), preventing damage to the unit or operator .
