Long Description
The Standard Meg-Ohm Box SRB-6 is a high-precision reference resistance box designed for calibration and verification of high-voltage insulation testers. Offering eight resistance values from 2MΩ to 200GΩ, this model is suitable for laboratories, R&D units, cable manufacturers, and industries requiring accurate insulation resistance standards.
The SRB-6 is fully compatible with Million Meg-Ohm Meters (MM-107, MM-108D) as well as a wide range of Digital Insulation Testers, making it a versatile tool for quality control and calibration applications.
For lower resistance values up to 20MΩ, the instrument supports test voltages up to 1000V, while for higher values such as 200MΩ and above, it safely operates at up to 5000V. With an accuracy of ±5%, it provides reliable and consistent readings necessary for high-voltage testing environments.
One of the standout features of the SRB-6 is its integrated dehumidifier system, housed within a durable acrylic enclosure. This ensures stable and consistent resistance values even in high-humidity or monsoon conditions—an essential benefit for laboratories in tropical climates.
To achieve peak accuracy, the instrument is designed to deliver stable readings after a 1-hour warm-up period once powered on.
Engineered for long-term stability and precise performance, the SRB-6 is a trusted reference instrument for routine calibration, insulation testing, and quality assurance processes.
