TYPICAL APPLICATION:
Data loggers are instruments that record potential of the pipelines on a test point or in a survey mode. Some times starry current in the ground or the power lines in the area influence in the reading and data is not trustable. By installing this filter in the input of data logger you are able to recover real potential and filer the AC current. 

                     

Special Feature:

Filtered against starry current, telluric, and power lines noise.

Very High input Resistance (more than 1000 Mega Ohm) and low output Resistance.

Filters 50 or 60 HZ and Gain -40 or 60 db (1/100, 1/1000)

Rechargeable battery.

Stabilized and filtered input.

Low consumption rate.

Temperature Stabilized.
