PROBLEM TO BE SOLVED: To readily control a chemical liquid as a consumable product of an analytical instrument separately disposed in a wide region by a central control center by a method wherein information in a chemical liquid use amount of a plurality of analytical instruments is gathered via a transmission means and the chemical liquid consumption is computed in each of respective analyses to display. SOLUTION: First, when a chemical liquid usageΔV in transmission data from a water quality analyzer is transmitted as direct data, its value is accumulated. Furthermore, when data is transmitted as an operation countΔN of a chemical liquid supplying quantitative pump, it is converted into the chemical liquid usageΔV to accumulate. In the case of an unquantitative pump, precision of quantitativeness is inferior, and its operating timeΔT is transmitted as data, and in this case, it is converted into the chemical liquid usageΔV to accumulate. With respective accumulated values as a chemical liquid accumulated consumption Vx, a difference from a sample liquid container (cartridges 79, 80, 81) capacity Vs is acquired to obtain a balance of the chemical liquid. On the other hand, a daily consumption V is calculated from each chemical liquid usage obtained from transmission data, and a quotient to a chemical liquid balance is acquired to obtain a remaining usable day number (N).
