Corrosion specification
1.  Automatically 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.
