1、 Industrial dissolved oxygen analyzer
Using high-performance CPU chips, high-precision AD conversion technology, and SMT surface mount technology, multi parameter measurement and temperature compensation are completed, with high instrument accuracy and good repeatability. The current output and alarm relay adopt photoelectric coupling isolation technology, which has strong anti-interference performance and achieves remote transmission. Alarm signal isolation output, alarm limit can be set arbitrarily, alarm hysteresis cancellation.
