Conductivity meter

DDS-11A (Shu Xian) type conductivity meter (hereinafter referred to as the instrument) is laboratory measurement of water solution conductivity is necessary, it is widely used in petroleum chemical industry, biological medicine, sewage treatment, environmental monitoring, mine metallurgy and other industries and universities and research institutions. If equipped with appropriate electrode constant, also can be used to measure the semiconductor, nuclear power industry and power plant water or ultra pure water conductivity.

The instrument of the main features are as follows:

The instrument adopts 1/2 3 LED digital tube display, clear display, high precision measurement;

It has the electrode constant compensation function;

Manual temperature compensation function is the solution;

It has a 0~10mV signal output.

The instrument main technical performance:

Measuring range: 1, the measuring range of the instrument is (0~2 * 105 S/cm), the instrument is divided into five range, the range between the band switch manual switch, see Table 1

The basic error of 2, electronic unit: + 1% (FS + 1) words

The basic error of the instrument, 3 (FS): 1.5% + + 1 words.

4, temperature compensation range: (5~35) C
