壁挂式ｐＨ值测定仪日本最近研制出测定水溶液ｐＨ值的壁挂式测定仪，其特卢、是浸入测定液的传感器与显示ｐＨ值的主体部分是分离的，这在世界上尚属首例。传感器检测出的信号无线传送到主体，距离约５ｍ。主体最多能接收来自４个传感器的信号，可将多方位测定结果共同显... Wall-mounted pH measuring instrument Japan has recently developed a wall-mounted measuring instrument for measuring the pH of aqueous solutions. The TLU, which is the sensor immersed in the measuring solution, is separated from the main part showing the pH value. This is the first case in the world. The signal detected by the sensor is wirelessly transmitted to the subject at a distance of approximately 5m. The main body can receive signals from up to 4 sensors, and the multi-a
