 CT*3 polarization test probe

1.Product uses

CT*3S polarization test probe is a cathodic-protection-potential -measurement probe of buried steel pipeline with long-acting, high stability and eliminate IR drop. It's applicable to detect and monitor the cathodic protection potential of the underground or submerged buried steel pipeline anti-corrosion engineering. Through special structure of probe, it can eliminate *0% IR drop in soil medium. If coordinate with ZDC*2 intelligent potential measuring instrument, it can almost eliminate all IR drop of the soil medium and the result of detection & monitoring will be more accurate. The bulilt-in reference electrode of this probe is Cu/Cu S*4 electrode or zinc electrode. This product is developed referred to NACE TM***4 "Measurement Techniques Related to Criteria for Cathodic Protection on Underground or Submerged Metallic Piping Systems". It is complied with the requirements of the latest technology standards at home and abroad.

     3.   Main technological performance

3.1 Stable potential: Copper/saturated copper sulfate electrode *0土 5mV (relative to the CES electrode)

3.2Size: <|)*5x**0mm

            a)       Internal resistance: <1MO

            b)       Usage age: >*0 years

            c)       Eliminate IR drop: About *0%, Cooperate with the ZDC*2 intelligent potential measuring instrument will get better application effect.

     4.   Probe safekeeping

The lower part of the probe should be submerged in water when the measuring probe is not in use, in order to prevent the polarization specimens rust, you can use a sacrificial anode connect with the probe's no.2 or no.3 wires. Even if the probe's
