  FSG*3C cathodic protection potential-Intelligent collection instrument

 

1             Product uses

Intelligent potential-collection instrument can acquisition Pipeline ground potential of Buried Metal Pipeline and send Pipeline ground potential to appointed *1 -digits SIM card through GSM.

Intelligent potential-collection instrument adopts daily***- times sending mode. The ****0mAh lithium battery installed internally ensure that the FSG*3C intelligent test pile can normal work for 8 years (under once-send mode every day).
