Long Description
The Standard Meg-Ohm Box SRB-4 is a precision-engineered reference resistance box designed for accurate high-voltage insulation testing. Equipped with eight carefully calibrated resistance values from 2MΩ to 200GΩ, it is ideal for laboratories, calibration centers, cable testing units, and industries that rely on accurate insulation resistance measurements.
Engineered for seamless integration with Million Meg-Ohm Meters (MM-107, MM-108D) and various Digital Insulation Testers, the SRB-4 provides reliable and repeatable performance across a wide range of testing environments. It supports voltages up to 1000V for lower resistance ranges and 5000V for higher ranges, ensuring safe and accurate operation.
A unique highlight of the SRB-4 is its built-in dehumidifier system, which ensures measurement stability even in high-humidity or monsoon conditions—an essential advantage for laboratories and field technicians working in humid climates.
Constructed with a durable acrylic enclosure and designed for long-term stability, the SRB-4 delivers dependable accuracy within ±5%, making it a trusted reference standard for routine insulation testing.
