自动成分分析仪器普遍采用电子电位差计作为二次显示仪表,三次仪表均配备磁电式毫伏计(或动圈式指示仪)远距离显示。在实际应用中,为了能在远距离准确了解并记录仪器的分析数据,更好地指导生产,不少单位使用的三次仪表,已改为电子电位差计,进行显示记录。由于分析仪器与显示仪表是配套供给,所以采用 Automatic component analysis instrument commonly used electronic potentiometer as a secondary display instrument, the three instruments are equipped with magnetic millivoltmeter (or moving coil indicator) long-distance display. In practical application, in order to accurately understand and record the analytical data of the instrument at a long distance and better guide the production, the three instruments used by many units have been changed to the electronic potentiometer to display the records. As analytical instruments and display instruments are supporting the supply, so use
