PURPOSE:To reduce the liquid level difference of respective thermostatic ovens and to keep the temperature of a substance to be measured at a constant level by arranging connection ports of liquid level adjusting pipes coupling respective thermostatic ovens in a direction applying pressure due to flow liquid in the ovens uniformly. CONSTITUTION:Thermostatic water from respective injection ports 17a-17d is jetted through respective jetting ports 19a-19d in respective thermostatic ovens 11A-11D and the thermostatic water is circulated in the arrow X direction at a fixed flow rate. Respective thermostatic ovens 11A-11D are coupled with each other by the water level adjusting pipes 13-16 and their connection ports 12a'- 12d' are opposed to the water flow direction and arranged in the direction applying pressure uniformly. If the flow rate and positions are fixed, water flow depends upon only the water pressure and the thermostatic water is made flow into the thermostatic ovens 11A, 11B so that the water level difference between both the ovens is uniformed through a pipe 13 and other ovens are also controlled. Consequently, the liquid level difference of each oven can be reduced and the temperature of the substance to be tested can be kept at a constant level. |
