Description
American Innovations is now offering
the Bullhorn® i-series CP Logger, a small, rugged device ideal
for taking cathodic protection measurements using a high
impedance, filtered input. Potential applications include:
-
 Pipe-to-soil
readings for depolarization studies
- Stray current interference
studies
- Verifying polarization
during interruption surveys
- Logging rectifier output
current, voltage or bond current.
- Any logging application that
requires multimeter type DC input characteristics.
The CP Logger has adjustable
input ranges (1-100 mV, 1-10 V and 0-100 V) with excellent
resolution and accuracy. Battery life is sufficient for up to
ten days. It can be used in conjunction with AI’s MicroMax
GPS200 current interrupter for interference surveys.
The AI CP Logger is easy to use
and setup. It comes with software for installation, downloading,
and data analysis/presentation. See next page for Technical
Specifications. |
