Product Overview
The ZX67 switch-type DC standard resistance box is a precision adjustable resistor for DC circuits, serving as a reference tool for resistance calibration or thermistor verification. With a resistance range of 0.01Ω to 11111.11Ω and a minimum step of 0.01Ω, it meets diverse experimental requirements in laboratories, educational institutions, and industrial settings. Its robust construction ensures reliable performance in electrical measurements.1610
Key Features
Featuring sealed low-pressure switches, the ZX67 minimizes contact resistance variation and extends service life without frequent maintenance. Precision alloy resistors undergo rigorous aging processes for enhanced stability. Multi-range current compatibility (e.g., 3A for ×0.01Ω, 0.01A for ×1000Ω) ensures safe operation. The unit boasts insulation resistance exceeding 500MΩ and withstands 2000V AC voltage tests. Its compact dimensions (340×165×148mm) facilitate easy integration into workspace setups.41416
Applications
Ideal for DC circuit calibration, academic training, and research projects, the ZX67 supports tasks such as verifying portable bridges or resistance thermometers. The linear scale panel provides clear readings, while a low zero-resistance of 0.01Ω simplifies measurements. Users can achieve wider resistance ranges through series connections, adapting to various voltage and current conditions.61619
