Benchtop insulation resistance meter RT-800

The high-temperature insulation resistance tester (infrared reflector furnace) is designed in compliance with GB/T 10518-2006 and referring to ASTM standards. It provides multiple safety protections for abnormal conditions (over-voltage, over-current, over-temperature) and a data-storage mechanism that preserves test data during computer faults or instantaneous power outages.

Features

• Multifunctional near-infrared reflector furnace enabling electrical testing in high-temperature, vacuum and atmosphere environments.
• Water-cooling device integrated for faster and more efficient cooling.
• Support for uniform temperature rise and step temperature rise measurement modes.
• Imported temperature sensor combined with PID automatic temperature control for accurate temperature regulation.
• Near-infrared heating delivers more even sample heating with no induced current, improving measurement accuracy.
• 10-inch imported touch screen with integrated mechanical structure for stable, user-friendly operation.
• Imported high-frequency test lines for stronger anti-interference capability and higher acquisition accuracy.
• Dexinmag control & analysis software compatible with functional test platform systems and providing data save/restore features.

Advantages & measurement improvements

• Anti-interference design and advanced test/analysis technology improve weak-signal acquisition; achieved measurement resolution down to 1 fA (10^-15 A) for ultra-high resistance/weak-signal testing.
• Design eliminates influence of power-grid harmonics on acquisition accuracy via a dedicated anti-interference module.
• Automatic averaging function to remove irregular input deviations (improves stability when charging currents or contacts are unstable); the current input uses a large-diameter triaxial connector with inner shield tied to GUARD (COM) and outer shield to GROUND for both interference stability and high-voltage safety.
• “Wait-before-measure” procedure (temperature holding time) to ensure more uniform sample heating prior to measurement, improving scientific accuracy of results.
• High-speed heating and cooling enabled by high-energy infrared lamps, gold-coated reflector and optional gas cooling; water cooling standard for rapid cooling.
• Flexible heating modes: constant speed, step (heating/cooling), cyclic impact, vacuum, atmospheric, and stage heating furnace options.
• Phase-shift trigger technology can reduce control fluctuation to approximately ±0.25°C for precise temperature control (complements the controller's regulation features).

Operational software & compatibility

• Software platform developed in LabVIEW; supports data/image save and power-off data recovery; compatible with Windows XP/7/10.
• Multilingual interface (Chinese/English), status monitoring, legend management, user permissions, fault alarm and customizable test report export (Excel, PDF).
• Software compatible with instruments: Keithley (6487, 6514, 6517b), Keysight (B2985A, B2987A), Tonghui (2683A, 2684A).
