This instrument is a panel instrument for on-line monitoring of industrial process conductivity. Range switch over and constant check can both be freely set and adjusted through the operation component on the rear panel; unique signal collecting and processing technology and special thick film circuit are adopted to make measurement accurate and operation stable; there are also other features such as linearized data, automatic temperature compensation, not subject to the length change of cable and maintenance-free. It's an ideal auxiliary instrument of various types of small pure water equipment.
