PURPOSE: To obtain a device which is excellent in both measurement accuracy and the temperature controllability of a dialyzing solution, small in size, convenient for use and inexpensive by providing the circulating boosting pump for the dialyzing solution at a dialyzing solution introducing path from the primary room of a welding tank to the introducing port of a dialyzer and being equipped with a temperature control means at the arbitrary position of a circulating circuit.
CONSTITUTION: The weighing mode is shifted by the instruction of a microprocessor 31. In the mode, the temperature adjusted fresh dialyzing solution temporarily stored at the primary room of a weighing tank 27 comes through a branch tube J to a circulating boosting pump 26, a part is temperature-adjusted through a solution returning circuit D and a heater 39 again, supplied through a constant flow quantity 41 to a dialyzer 21 and the ultrafiltration is executed. At this time, since most of the fresh dialyzing solution stored in the primary room of the weighing tank 27 is temperature-adjusted through the solution returning circuit D again, the temperature reduction during the weighing mode period can be minimized. Consequently, the temperature difference between the fresh dialyzing solution in the primary room of the weighing tank 27 and the exhaust analyzing solution in a secondary room does not exist, the equal volume is obtained and a correct water removing quantity can be measured.
