【English Introduction】
The ZHT2000 Precision Digital Pressure Gauge is a high-performance intelligent measuring instrument specifically designed for laboratory applications. Integrating advanced diffused silicon sensing technology with an intelligent processing system, this device delivers accurate pressure measurement solutions for diverse experimental scenarios. Featuring lithium battery power supply as a core design element, it combines portability with extended operation time, making it ideal for continuous measurement tasks in field laboratories or environments without external power sources.
At its core lies a highly stable diffused silicon pressure sensor chip. Through precision temperature compensation algorithms and digital signal processing technology, the device achieves exceptional measurement stability and repeatability. The optimized sensor structure effectively minimizes the impact of ambient temperature variations and electromagnetic interference, maintaining ±0.1% FS typical accuracy across a broad temperature range of 5℃ to 45℃. With a measurable range spanning from -100kPa to 60MPa (customizable extensions available), it supports real-time unit conversion between kPa, MPa, bar, and psi.
The 3.5-inch high-contrast LCD display offers dual digital/analog presentation modes, ensuring clear and intuitive readings. User-centric interface design incorporates practical functions including real-time pressure curve display, data hold, peak value recording, and overpressure alarm protection. The aluminum alloy housing meets IP54 protection standards, complemented by shock-absorbing structural design for reliable performance in demanding laboratory environments.
The lithium battery module employs advanced power management technology, delivering over 200 hours of continuous operation on a single charge. Equipped with Type-C fast charging capability, it completes full recharge cycles within 2.5 hours. Wireless Bluetooth connectivity enables seamless data transmission to PC analysis software, facilitating in-depth data processing and report generation. This instrument finds applications in fluid dynamics research, equipment calibration, educational experiments, medical device verification, and other technical fields, serving as an essential tool for modernizing laboratory measurement capabilities.
