Description
SR-2 Standard Resistor for High-Accuracy Calibration
The SR-2 Standard Resistor from Hioki is a professional-grade calibration box engineered to ensure the accuracy and reliability of super megohmmeters used in high-insulation resistance measurements. Built with 24 ultra-precision resistors, the SR-2 provides stable and repeatable resistance values across a wide range, making it an essential tool for calibration laboratories, manufacturing facilities, and quality assurance environments.
Designed to operate safely at voltages up to 1,000 V DC, the SR-2 Standard Resistor covers resistance values from 1 MΩ to 10,000 MΩ, allowing technicians to verify meter performance at multiple calibration points. Each resistor element is encased in a sealed metal enclosure that minimizes the influence of temperature fluctuations, humidity, and external noise. This robust construction ensures long-term stability and dependable measurement results, even under demanding test conditions.
The terminal plate design enables flexible connection configurations, allowing users to select individual resistance values or combine elements as required. This versatility simplifies calibration procedures and supports a wide range of test scenarios, from routine instrument checks to detailed performance validation.
The SR-2 Standard Resistor is specifically designed for use with super megohmmeters that measure high insulation resistance in materials such as cables, electronic components, insulating films, and industrial equipment. By providing traceable calibration support, it helps maintain measurement confidence, comply with internal quality standards, and reduce the risk of inaccurate readings in critical testing applications.
Supplied with an inspection data sheet, the SR-2 Standard Resistor delivers transparency and documentation support for audit and compliance needs. Its compact footprint and durable construction make it a dependable calibration solution for both laboratory benches and controlled industrial environments.
