Product Introduction:
UHV-H100P Contact Resistance Tester is suitable for high and low voltage switch contact (loop) resistance, cable line DC resistance value of high precision measurement, also suitable for other need large current, micro resistance measurement occasions.
Product Features:
1. High-Current Output
Utilizing advanced switching power supply technology, the instrument delivers a continuous, high-current output over extended durations. It overcomes the limitations of pulsed power supplies that rely on instantaneous current, effectively penetrating switch contact oxide films to ensure reliable and accurate test results.
2. Exceptional Stability
Even under conditions of significant electromagnetic interference, the last digit of the LCD reading remains stable within a range of ±1 count. This ensures highly consistent readings and excellent measurement repeatability.
3. Superior Precision
Equipped with dual high-speed 16-bit Σ-Δ AD converters and digital signal processing technology, the instrument achieves a maximum resolution of 0.01 μΩ. It is one of the most stable contact resistance testers available in China with such resolution, delivering performance that surpasses many imported high-current micro-ohmmeters.
4. Intelligent Operation
Powered by a high-performance port CPU, the system automatically selects the appropriate measurement range based on signal strength, ensuring optimal accuracy. An integrated over-temperature protection circuit automatically cuts off the output current if the instrument exceeds preset temperature limits, guaranteeing safe operation.
5. Premium Build Quality
All critical components are sourced from internationally recognized manufacturers. The device incorporates a sophisticated temperature compensation circuit to minimize the influence of ambient temperature on measurements. Military-grade connectors further enhance durability and vibration resistance.
6. Advanced Functionality
Users can freely select test currents of 50A or 100A and set test durations anywhere between 5 and 599 seconds. This addresses the shortcomings of comparable instruments that lack configurable test times or offer limited continuous operation, placing this device far ahead in performance.
7. User-Friendly Interface
Data entry is simplified via a rotary mouse, providing quick and intuitive operation. The instrument allows independent setting of date and time, supports real-time data saving, and enables on-demand printing of test results.
8. USB Data Transfer
Measurement data can be transferred directly to a USB flash drive via the built-in USB interface. Combined with dedicated PC software, this allows for in-depth analysis and further processing of test data.
9. Portable Design
Compact and lightweight, the instrument is easy to transport and ideal for both laboratory and field applications.
