数字电导率仪(DDS-11A),山东盈嘉供应

数字电导率仪(DDS-11A)
DDS-11A(数显)型电导率仪(以下简称仪器)是实验室测量水溶液电导率必备的仪器,它广泛地应用于石油化工、生物医药、污水处理、环境监测、矿山治炼等行业及大专院校和科研单位。若配用适当常数的电导电极,还可用于测量电子半导体、核能工业和电厂纯水或超纯水的电导率。
仪器的主要特点如下:
◆ 仪器采用3 1/2位LED数码管显示,显示清晰,测量精度高;
◆ 具有电导电极常数补偿功能;
◆ 具有溶液的手动温度补偿功能;
◆ 具有0~10mV讯号输出。
仪器的主要技术性能:
1、测量范围:仪器的测量范围为(0~2×105μS/cm),仪器分成五档量程,各档量程间采用波段开关手动切换,见下表1
2、电子单元基本误差:±1.0%(FS)±1个字
3、仪器的基本误差:±1.5%(FS)±1个字。
4、温度补偿范围::(5~35)℃
量程档 测量范围 分辨率
2μS/cm (0.001~2)μS/cm 0.001μS/cm
20μS/cm (0.01~20)μS/cm 0.01μS/cm
200μS/cm (0.1~200)μS/cm 0.1μS/cm
2mS/cm (0.001~2)μS/cm 0.001mS/cm
20mS/cm (0.01~20)μS/cm 0.01mS/cm
表1
注:测量高电导率时,一般采用大常数的电导电极,当电导率≥10000μS/cm时,采用常数10的电导电极,当选用常数为10的电导电极时,测量范围扩展为2×105μS/cm;
