Long Description
The Standard Meg-Ohm Box SRB-20 is a high-accuracy reference resistance box engineered for precise calibration of insulation testers and high-resistance measurement equipment. Featuring nine fixed resistance values from 1MΩ to 20GΩ, it is ideal for applications requiring reliable and traceable insulation resistance standards.
The SRB-20 is designed for seamless use with Million Meg-Ohm Meters (MM-107, MM-108D) and a wide range of Digital Insulation Testers. For resistance values up to 200MΩ, it supports test voltages up to 1000V, while higher ranges—1GΩ, 2GΩ, and 20GΩ—are rated for up to 5000V, ensuring safe and accurate operation in demanding high-voltage environments.
What sets the SRB-20 apart is its superior accuracy of ±1%, making it a premium option for calibration laboratories, quality control facilities, and industries that require stringent measurement precision. Built with high-stability resistive elements, the SRB-20 maintains long-term reliability even under frequent use.
Ideal for electrical labs, cable manufacturers, research institutions, and testing centers, the SRB-20 provides the consistency and precision required for professional insulation resistance calibration.
