Gravity 工業級電導率 類比型電導率計工業版 K=1

電導率是電阻率的倒數,與物質傳送電流能力的大小有關,在液體中常以電阻的倒數電導來衡量其導電能力的大小。水的電導是衡量水質的一個重要指標,它能反映出水中存在的電解質的程度。
DFRobot Gravity: 模擬電導率計工業版K=1 專門用於測量水溶液的電導率值,評估水質狀況,常用於水培、水產養殖、環境水檢測等領域。
作為模擬電導率計的升級版,工業版極大的改善了探頭耐用度,可以實現7×24 小時全天候監測電導率變化;集成PT1000鉑熱電阻,測量溫度補償讀數更簡單。支持3~5V 寬電壓輸入,兼容5V 和3.3V 主控板;輸出信號經硬件濾波,抖動小;交流激勵源,有效降低了極化效應,提高精度的同時延長電極的壽命;配套軟件庫自帶校準程序,簡單方便;還附贈校準液、隔離柱螺絲零件包、防水航空插頭等實用配件,助您快速搭建電導率監測平台
本產品配合主控板(如Arduino) 與配套的軟件庫,就可迅速搭建出一套電導率檢測儀,即插即用,無需焊接。DFRobot提供多種水質檢測傳感器產品,尺寸與接口統一,滿足各類水質檢測的需求,也適合搭建多參數水質檢測儀。
工業電極適合長時間浸泡在液體中測量,如需更高精度或更大量程的電導率探頭請選購實驗室電極(Gravity: 模擬電導率計V2 (K=1)-液體傳感器-DFRobot創客商城)

Gravity: Analog Electrical Conductivity Sensor PRO (K=1)

Conductivity is the reciprocal of an object’s resistivity. It represents a material’s ability to pass a current. In a liquid, conductivity is a measure of a solution’s ability to conduct electricity and can reflect the amount of dissolved or salinity of a water source, so it’s an important parameter in water quality monitoring.

DFRobot Gravity: Analog Electrical Conductivity Sensor PRO(K=1) is specially used to measure the conductivity in aqueous solutions, and then to evaluate the water quality. These conductivity sensors are often used in hydroponics, aquaculture, environmental water detection, and other fields.

As an upgraded version of the analog electrical conductivity meter, this pro version has greatly improved probe endurance, which can be used in 24/7 conductivity monitoring. Besides, the integrated PT1000 platinum resistance thermometer makes it easier to measure the compensated temperature data.

It supports 3-5V wide voltage input and is compatible with 5V and 3.3V main control boards. The output signal is filtered by hardware and has low jitter. The excitation source adopts an AC signal, which effectively reduces the polarization effect, improves the precision, and prolongs the life of the probe. The supported library comes with a calibration program to allow you to get started easily. Besides, there are practical items in the package, like calibration solution, accessory kit, waterproof connector, etc., which can help you quickly build a conductivity monitoring platform.

With this product, a controller board (such as Arduino), and the software library, you can quickly build an electrical conductivity meter, plug-and-play, no solder required. DFRobot provides a variety of water quality sensor products with uniform sizes and interfaces, which not only meet the needs of various water quality testing but are also suitable for the DIY of multi-parameter water quality testers.

This is an industrial-grade probe and can be immersed in liquid for a long time. If you want a conductivity probe with higher accuracy or larger range, please select the laboratory probe (Gravity: Analog Electrical Conductivity Sensor /Meter V2 (K=1)).
