CPC cathodic protection recorder

CPC cathodic protection recorder: overview

The CPC is a watertight recorder: a single device is enough to take all the most common cathodic protection measurements. It connects via Bluetooth to the IHPC software, available on Windows and Android (IHPC Lite version), which streams the recorded data live every 0.5 s, displays and records them, and calculates minimum, maximum and average.

Ranges and accuracies: ON potential ±60 V DC (resolution 0.001 V, accuracy 0.04%), OFF potential ±10 V DC (0.001 V, 0.04%), AC voltage 0.1 to 60 V AC (0.2%), frequency 10 to 999.9 Hz (0.2%), DC current ±500 mA DC (0.05%), AC current 50 mA AC (0.2%), AUX potential ±100 V DC (0.02%), isolated-channel voltage ±100 V DC (0.1%), isolated-channel current ±100 mV DC (0.05%). The memory capacity is 27 to 70 million readings.

One instrument for the whole survey

A cathodic protection survey usually involves several instruments: a voltmeter for potentials, an AC meter for interference, an ammeter for currents. The CPC combines them and records everything. The technician saves time in the field, and the data go straight into the software instead of being copied by hand.

Which measurements

ON and OFF potentials during interrupted surveys, AC voltages and frequencies to detect interference from high-voltage lines or railways, DC and AC currents, and insulating joint checks through isolated-channel measurements. Its large memory also allows long-term logging to follow stray currents that vary through the day.
