Main technical characteristics and structure:

The apparatus by electrical control box and glass两面三刀equipment parts.
Apparatus structure shown in Figure 1. Panel equipped with a galvanometer, correction, determination of change-over switch, stirring adjustment knob, such as determination of the adjustment knob. Dual Platinum Electrode "measured" back-up socket and socket galvanometer electrical control box located in the back.
Instrument power rationale diagram shown in Figure 2. Power is divided into paying, DC group. AC power is 220V AC by the step-down transformer after 100V, 13V, 6V AC power into three groups. One, 100V, 13V AC motor for electromagnetic stirring; 6V AC after filtering by the rectifier into a DC, with magnetic stirrer using ND-D AC servo motor, a smooth start-up, external potentiometer-free level adjustment.
Measured by the DC power supply circuit, galvanometer, two platinum electrodes, measured correction switch, such as determination of the composition of the adjustment potentiometer. Galvanometer DC ammeter with 50UA1.5 class instruction to meet the general test requirements. Units such as the use of measuring instruments have higher test sensitivity, the available high-precision self-galvanometer (instrument equipped with a back-up the back of the box galvanometer sockets) were measured.
Glass apparatus of 10 ml, each cell dividing 0.05 ml, with brown glass bottle storage solution sets, the five cervical titration bottles (capacity about 250 ml) double-platinum electrode inserted and connected, such as drying tower.
