Description
Measurement of the condition of metal structures in soil is performed using reference electrodes, which can be purchased for measurements at various sites. Several versions of copper sulfate reference electrodes are available, both single-membrane and double-membrane.
Description
The ESMS-M2-VE model is an installation for monitoring the condition of underground metal objects. It should be ordered when accurate control of corrosion changes of pipelines and other steel structures is required. The modernized copper sulfate reference electrodes are equipped with an auxiliary electrode and have two membranes.
The operating principle consists in installing the device directly in the soil. The depth must correspond to the laying level of the object under inspection and must not be above the soil freezing depth. The conductors of the unit can be used as portable, and routed to a cover or to KIP.
Double-membrane modernized copper sulfate reference electrodes with auxiliary electrodes have the following advantages:
- bentonite chamber;
- fully sealed housing;
- durable construction material;
- the unit is ready for use;
- cable length can be specified by the customer.
When working with the reference electrodes, no preparation or electrolyte filling is required. The device housing is capable of withstanding impacts and other moderate mechanical damage. When purchasing reference electrodes, the customer can independently choose the required cable length. The final order price depends on this parameter.
Technical features
Several modifications of reference electrodes are available. In addition to the basic version, the manufacturer offers the ESMS-VE-M model. This device is supplemented with an auxiliary electrode. The housing is filled with copper sulfate, with a pure copper electrode inside. Contact with the soil surface is maintained by an ion-exchange membrane located in the lower part. The auxiliary electrode is located on the side of the reference electrode housing.
Each cable has tags with information and lugs for connection to KIP. This makes installation, operation, and maintenance of the unit convenient and clear.
