Claims (1)
温度で変色する複数のエレメントから成る液晶と
、液晶の各エレメントに相対的に位置決め自在で
かつエレメントの変色に伴い反射率の変化を検出
する光センサーと、光センサーからの検出信号を
受けて熱源の発熱量を制御する制御装置とを備え
たことを特徴とする液晶利用の恒温槽。 A liquid crystal that is attached to a temperature-controlled area and consists of multiple elements that change color at different set temperatures, and an optical sensor that can be positioned freely relative to each element of the liquid crystal and detects changes in reflectance as the elements change color. and a control device that controls the amount of heat generated by the heat source in response to a detection signal from an optical sensor.
