First,summary
DDS-11C type digital conductivity instrument is widely used on the electrical conductivity measurement of distilled water, deionized water, drinking water, boiler water, industrial wastewater and general liquid, can also be used for the purity of electronic, chemical, pharmaceutical and power station testing high pure water。
Instrument characteristics
1, using 3 LED bit 1/2 digital display, clear and intuitive.
2, excessive discharge of the display 1, eliminating the shift measurement error.
3, in the range of the measurement error is not more than 1%.
4, in the whole range of are equipped with constant electrode for "1". It can not only 0.1 ~ 0.05 Mu s / cm (10m to 20m Ohm) of high purity water conductivity detection, is suitable for the measurement of conductivity of liquids in general. Measurement range: 0 ~ 2 x 105 S/cm.
5, the measurement of high pure water without human induction phenomenon, and the display value is accurate.
6, the decimal point position and the high and low frequency measurement with the "range" synchronous transformation, direct measurement results without magnification by "". And has the function of temperature compensation。
Two, the main technical performance of the instrument
1, measuring range: 0.001 ~ 2 x uS/cm 10^4 (that is, 1000M ~ 5), divided into the following six range profile: (see manual)
2 shows: 3 1/2 bit LED.
3 measurement error: less than 1%F.S.
4 temperature compensation range: 10 ~ 40. Datum 25.
5 stability: 0.67%/24h.
6 power consumption: no more than 5W。
Three, the use of conditions
1, ambient temperature: 5 ~ 40;
2, relative humidity: less than 85%;
3, power supply: 220V + 10%, 50Hz + 2%.
