CRS456含有水位和水温传感器,以自身的的时钟和内存记录采集到的数据;封装在紧凑的不锈钢外壳里。用户可将CRS456放置在远程站点中,让其收集较长时间的数据;取回数据时,通过micro-USB接口连接到PC,将数据下载下来。长寿命的电池和坚固的结构,可以让你信任CRS456采集重要的数据。低成本和易于使用,使得CRS456成为很多不同应用的良好选择。CRS451与CRS456大致相同,除了外壳为不锈钢。
CRS456具有几个压力量程可选,CRS456是密封压力测量,无排气设计,所以为了最大限度的提高测量精度,需要对气压进行校正。
下载HydroSci软件,可简化CRS456的配置过程,用户可以监测地表水、地下水,或对标准泵进行测试。 HydroSci软件具备气压补偿功能,可通过表格或图形格式显示数据。

Requires a micro USB cable and HydroSci software running on a computer with Windows XP or later. HydroSci software is available for download.
HydroSci is used to configure and extract data from the CRS45X Recording Submersible Pressure Transducer and the OBS-3A Turbidity and Temperature Monitoring System.

CRS456: 1
The CRS451 and CRS456 are unvented and monitor sealed gage pressure. For maximum accuracy, the data should be corrected for barometric pressure. The barometric pressure data from a nearby weather station or other monitoring platform can be used.
