数字气压表高原区专用精密气压表
产品概述
数字气压表高原区专用精密气压表是一款专为高海拔环境设计的高精度大气压力测量仪器，采用硅压阻式数字传感器技术，确保在高原低气压环境下仍能保持稳定可靠的测量性能。该产品结构轻巧、功耗低，支持干电池或直流电源供电，便于野外携带和使用，适用于实验室、矿山、气象站等对测量精度要求较高的场景。110
核心特点
该气压表具备自动温度补偿和非线性校准功能，能有效适应高原地区温差大的环境特点，确保数据准确性。LCD液晶屏直接显示气压值，支持hPa（百帕）、mmHg（毫米汞柱）、inHg（英寸汞柱）三种单位切换，满足不同场景需求。仪器采用高稳定性传感器，无需硬件调整即可实现零位修正，操作简便。抗振设计使其在运输和野外作业中更具耐用性。212
技术参数
气压测量范围为500.0hPa～1070.0hPa，分辨率达0.1hPa，精度分为A级（±0.3hPa）、B级（±0.5hPa）、C级（±1.0hPa）三档。工作环境温度为-15℃～50℃，湿度≤90%RH（无凝结），内置3节5号电池供电，续航时间长。外形尺寸为185mm×133mm×60mm，重量仅450g（含电池），适合高原地区便携使用。1117
应用场景
特别适用于高原气象监测、地质勘探、环保监测等领域，可替代传统水银气压计，避免汞污染风险。其轻量化设计和低功耗特性尤其适合无人区或移动式测量任务，如高原科考、矿山安全监测等。616
Product Overview
The high-altitude digital barometer is a precision instrument designed specifically for measuring atmospheric pressure in plateau regions. Utilizing silicon piezoresistive digital sensor technology, it ensures stable and reliable performance even under low-pressure conditions. Compact and energy-efficient, it supports both dry cell and DC power supply, making it ideal for field applications such as laboratories, mines, and meteorological stations.110
Key Features
Equipped with automatic temperature compensation and nonlinear calibration, the barometer adapts to significant temperature fluctuations in high-altitude areas while maintaining accuracy. The LCD screen displays real-time pressure readings with units switchable among hPa, mmHg, and inHg. Its high-stability sensor enables zero-point correction without hardware adjustments, simplifying operation. The vibration-resistant design enhances durability during transport and field use.212
Technical Specifications
The measurement range covers 500.0hPa to 1070.0hPa with a resolution of 0.1hPa, offering three accuracy levels: Grade A (±0.3hPa), Grade B (±0.5hPa), and Grade C (±1.0hPa). Operating temperatures range from -15℃ to 50℃ at ≤90%RH humidity (non-condensing). Powered by three AA batteries, it features extended battery life. Dimensions are 185mm×133mm×60mm, weighing only 450g (including batteries), optimized for portability in plateau environments.1117
Applications
Suited for plateau meteorology, geological surveys, and environmental monitoring, it serves as a mercury-free alternative to traditional barometers. Its lightweight and low-power design make it particularly effective for mobile tasks such as high-altitude expeditions and mine safety inspections.616
