Concentration sensor SJG1914c

SJG1914c is a new generation of all-englishmicrocomputer high-grade instrument of our company. It has an all-Chinese display, Chinese menu operation, full intelligence,multi-function, high measurement performance and strong environmental adaptability. It can be widely used in thermal power,chemical industry, etc. It is suitable for checking the concentration of regenerant in the process of preparing high-purity waterby ion exchange method, or for preparing boiler and pipeline pickling liquid, and continuously monitoring the concentration ofhydrochloric acid in the liquid. Technical indicators: 1.Measurement range: concentration(0.00~10.00)%HCL,(0.00~10.00)% NaOH(0.00 ~30.00)%H2SO4,(0.00~10.00)% NaCL(0.00~15.00)%HNO3;(Select) Accuracy (conductivity constant): ± (measured value + 0.5% of 25uS)Temperature (0 C~130 C) adjustable range. 2, galvanically isolated output: 4 ~ 20 mA (load <750Q); 3, output current error:≤土 1% FS; 4, temperature coefficient compensation range: (0 ~10.0)% / °C (adjustable) 5.Alarm relay:AC220V,3A; 6,RS485 communication interface; 7 , power:AC220V+ 22V,50Hz +1Hz; 8, protection level: lP65; 9, clock accuracy:主 1 minute / month 10, data storage: 1 month (1 point / 5 minutes) 11, data continuous power-down save time: 10 years 12, external dimensions: 146 (length) x 146 (width) x 108 (deep) mm,opening size:138×138 mm; 13, weight: 0.8kg; 14, working conditions: ambient temperature 0~60 ° C relative humidity <85%.
