➤ Product Introduction
Ultra-pure water must only be measured in a closed flow-through system. Once exposed to air, the dissolution of carbon dioxide forms carbonic acid, causing the water's resistivity to drop rapidly. Currently, many resistivity instruments can be blindly adjusted on-site. Due to the lack of awareness regarding ultra-pure water, this poses potential quality hazards in production processes that rely on ultra-pure water for process control.
With integrated sealed, flow-through, and flow-stabilizing measures, coupled with a precision conductivity cell, digital measurement acquisition, and mathematical model temperature compensation, this is a rare tool-type portable instrument for ultra-pure water verification both domestically and internationally.
The instrument uses a high-strength portable sealed case as its carrier to ensure the stability of internal components. It also integrates IoT technologies such as battery management and wireless transparent transmission, supporting setup and operation via mobile PC and APP interfaces, eliminating many uncertainties brought by conventional instrument technology. It is an essential tool companion for the high and ultra-pure water treatment industry.
