【English Introduction】
The YB2172B Intelligent AC Millivoltmeter is a precision measurement instrument designed for professional applications in R&D, production testing, and educational experiments. Featuring innovative circuitry, it accurately captures AC voltage signals ranging from 10μV to 300V, accommodating diverse measurement needs from weak signal detection to industrial-level applications.

Equipped with a high-definition LCD display, the device supports dual-channel simultaneous measurement readouts. Its user-friendly interface incorporates automatic range switching that intelligently detects input signal strength and selects optimal measurement ranges, enhancing operational efficiency. The built-in overload protection and temperature drift compensation ensure long-term stability with measurement errors below ±1.5%, even in challenging environments.

Constructed with industrial-grade ABS housing and non-slip base, the instrument combines durability with operational convenience. Its compact dimensions (265×105×350mm) and lightweight design (approx. 3.2kg) make it ideal for both benchtop use and field measurements. Independent channel control knobs with LED status indicators enable simultaneous signal comparison, providing efficient solutions for audio equipment calibration and communication system maintenance.

Supporting 20Hz-1MHz frequency bandwidth, this millivoltmeter accommodates various waveform measurements including sine and square waves. Specially optimized low-frequency response ensures precise detection of subtle signal variations in audio applications. Standard BNC interfaces allow seamless integration with oscilloscopes and signal generators to form complete testing systems.

The product package includes a shock-resistant carrying case, probe accessories, and multilingual manuals for immediate deployment. Our service network provides 24-month quality assurance and professional technical support, ensuring prompt assistance nationwide.
