CD5系列用于测量溶液的电导率，总溶解固体，盐度和温度
基于微处理器：CD5系列内置高性能CPU，它可以工作约200小时连续与9伏电池
单点按钮校准：具有单点校准功能的仪表，允许使用标准电导率溶液，您只需要在25°C设置校准溶液的电导率值，将电导率电极浸入溶液，然后按Enter键，仪表将自动校准
自动标准溶液识别：在校准时，如果您错误地使用电导率溶液，仪表将显示错误
电导率自动量程：测量电导率或总溶解固体时，具有自动量程功能的仪表，电极浸入溶液后，CD5系列将快速响应和转换范围
自动温度补偿：仪表自动识别温度传感器，并在温度传感器连接到主机后测量温度，如果电导电极连接到仪表，仪表将进入自动温度补偿
可调温度系数：溶液含有不同离子，通常有不同的温度系数，CD5系列可设置在0和3.9％的摄氏度
可调电解池常数：当测量浓度较高或较低的溶液时，应选择不同的电导率常数，仪表有三个电极常数可供选择，可分别保存不同恒电极的测量值，设置后常数，您在更换新电极时无需再次校准
可调TDS系数：根据电导率理论，当测量溶液的总溶解固体时，需要估算TDS系数，CD530 / 540可设置在0.01至1.00的范围内，这可以确保测量值的准确性
保持功能：仪表带保持功能，按MEAS / HOLD键，仪表瞬时冻结读数，便于查看
消息指示器：带有操作消息指示器的仪表，当您需要设置或测量时，消息指示器将帮助您做什么以及如何做，可以在其指南下设置参数或选择功能
保存数据：仪表可以保存64组数据，按保存键，仪表将存储当前测量值，序列号，日期，时间等信息
输出数据：可通过USB通讯接口将数据发送到电脑，可通过软件打印输出测试报告

CD5 series are used to measure conductivity, total dissolved solid, salinity and temperature of solution
Microprocessor-based: CD5 series has built-in high performance CPU, it can work about 200 hours continuously with 9 volt battery
Single point push-button calibration: meter with single point calibration function, it is permitted to use standard conductivity solution, you need only set conductivity value of the calibration solution at 25°C and immerse conductivity electrode into solution, then press enter key, the meter will be calibrated automatically
Auto standard solution recognition: in calibration, meter will display error if you use conductivity solution by mistake
Auto-ranging for conductivity: meter with auto-ranging function when measure conductivity or total dissolved solid, after electrode immersed in solution, CD5 series will fast response and convert range
Auto temperature compensation: meter will recognize the temperature sensor automatically and measure temperature after temperature sensor connected to the host, if the conductivity electrode connected to it, the meter will enter automatic temperature compensation
Adjustable temperature coefficient: solution contains different ions, usually have different temperature coefficient, CD5 series can be set in the range of 0 and 3.9% per centigrade degree
Adjustable cell constant: when you measure solution with higher or lower concentration, you should choose different constant of conductivity electrode, the meter with three cell constants for your choose, it can save the measured value for different constant electrode separately, after setting the constant, you needn't calibrate it again when replacing a new electrode
Adjustable TDS coefficient: according to the theory of electrical conductivity, you need estimate TDS coefficient when measure total dissolved solid of solution, CD530/540 can be set in the range of 0.01 to 1.00, which can ensure accuracy of measured value
Hold function: meter with hold function, press MEAS/HOLD key, the meter momentarily freezes reading for easy viewing
Message indicator: meter with operational message indicator, when you need setup or measurement, the message indicator will help you what you can do and how do it, can set parameter or select functions under it's guide
Save data: meter can save 64 data sets, press save key, and the meter will store current measured value, serial number, date, time and other information
Output data: data can be sent to computer through USB communication interface, you can print out test report via software
