The coupon are composed of an XC48 steel pellet with a calibrated and ground surface.

Removable coupons allow measurements and recordings to be made on structures subject to cathodic protection.

ADCA found it natural to develop a removable annular indicator (T2A) in order to make the potential measurement even more precise.

The coupons associated with a measuring well are intended to be placed near the pipes. They are associated with a DN 50 well to be able to slide an electrode into it.

The stake witnesses were designed to carry out cathodic protection measurements. They are

put in place for the time to take a measurement and then removed. They are not intended to be

permanently installed.

The coupons associated with a measuring well are intended to be placed near the pipes. They are associated with a DN 50 well to be able to slide an electrode into it. The coupon unscrews to be changed quickly.

This coupon is intended to be installed permanently in manholes.

Interchangeable steel tips for the stake coupons associated with a measuring well and the stake coupons for sight glass.

This coupon is intended to check corrosion on a witness placed in an environment. The thickness of the coupon is calibrated and measured precisely then it is packaged under vacuum. This thickness is recorded on a certificate.

The PC Multi is intended to be buried, positioned a few tens of centimeters from the pipe. This equipment allows you to insert corrosion coupons and/or measuring electrodes.
