HOBO 水位数据记录仪豪华套装（100英尺）
这款省钱套装将高精度水位测量与开箱即用的便捷性相结合，包含立即开始记录所需的一切。
Overview
这款经济实惠的套件将高精度水位测量与开箱即用的便捷性相结合，包含立即开始记录所需的一切。它非常适合监测水井、溪流、湖泊和淡水湿地的水位与温度，以及气压。
该套件包含：
- U20-001-02 HOBO数据记录仪（100英尺量程）
- U20-001-04 HOBO数据记录仪（13英尺量程，用于气压测量）
- U-DTW-1 HOBO防水数据传输器，带5个可互换耦合器
- U20-CASE-1 便携箱
- HOBOware Pro软件
与其他HOBO水位记录仪一样，100英尺版本具有卓越的性价比和易用性，无需维护繁琐的通气管或干燥剂。
Features
- 防雷保护；无长信号线，电子元件采用不锈钢外壳屏蔽
- HOBOware Pro软件可轻松转换为准确的水位读数，完全补偿气压、温度和水密度的影响
- 多速率采样可在关键时期（如泵启动或停止时）实现更快的采样
- 提供四种深度范围
- 适用于水井、溪流、湖泊、湿地和潮汐区域
- 无通气管设计，部署简便可靠
- 耐用的陶瓷压力传感器
