Corrosion specification

1. Automatical y monitor the ambient temperature without the help of thermometer.

2. Permanently fixed cupric sulfate-copper electrode. No need to perfuse and change cupric sulfate saturated solution both before and after the test, in order to avoid damage to the environment and testers.

3. Two measurement methods: potential method and gradient method, with potential electrode and gradient electrode respectively.

4. Measuring Potential: ±2000mV;

5. Test accuracy: ± 1mV;

6. Measuring Space: 1-99 cm (adjustable)

7. Environment Requirement: Ambient Temperature:-10°C~+40°C, to avoid direct exposure to the sun for a long time. Relative Humidity:<90%RH; Electromagnetic Interference: no strong alternating electromagnetic field.
