• Potential Difference in 24hours <±0.5mV.
•  Diameter 5cm and Height 10cm.
•  Weight 0.25 Kg.
•  In the color of Red and Blue.

Field Use Instructions:

1). Use a small hammer with a flat-head shovel to plan out the electrode pit at the designated electrode position, so as to see moist and fresh soil.

2). Place the bottom of the non-polarizable electrode vertically in the middle of the electrode pit, and press the electrode firmly to make it come into close contact with the soil. Be careful not to shake the electrode after pressing.

3). If it is a short period measurement, such as scanning the surface of a middle ladder, just press and hold the electrode will be OK . If you need to observe for a long time, you need to bury the electrode around densely with soil.

4). If the work area is in the dry season and the surface soil is very dry, you must firstly water the electrode pit and then press the electrode to measure.

Additional Instructions:

Applications:

1).  Before applications, the electrodes will be connected in parallel and bottom of the electrodes willl be  immersed in a saturated salt solution for about 2 minutes and then taken directly to the field for use.

2).  If there is a requirement for the electrode range,  please choose two electrodes randomly in the same container and use  them in pairs.  The  selection  principle  is: Use digital multimeter to measure potential  difference of two non-polarizable electrode   and the appropriate combination should be  <2mV.

Storage and Maintenance:

1).  Keep the electrodes in dry places and avode light.

2).  Keep the electrodes clean and pile in horizontal direction.

Warning:

1).  When selecting electrodes, you must use a digital multimeter, not an analog meter.

2). The electrode clip  should not be soaked or wetted with salt water, otherwise  the clip should be wiped dry immediately or replaced.

3). If you want to know the grounding of the electrode by measuring the resistance, you may  measure the AC potential difference or the DC potential difference (natural potential) and judege wheter the  circuit is OK or not.

Prohibit:

1).  It is strictly prohibited to measure the resistance of electrodes indoors.

2). Directly  measuring  on  grounding resistance is strictly prohibited in the field.

3). If necessary, it is recommended to do  the measurement after field work and the electrodes used  should be connected in parallel with bottom immersed in the saturated salt solution for at least 30 minutes.

Notice:

In order to prevent excessive pulling of the wire in field use, it is recommended to tie the wire to the draw rope.
