The Coupon Holder holds a Corrosion Coupon into the fluid whose corrosion rate has to be measured. It is possible to have holder for all corrosion coupon types (Strip, Disc, Scale, Crevice and Rod).

Depending to the use, the Corrosion Coupon Holder can be:
- Single Coupon Holder. it holds the coupon in Top, Middle or Bottom of Line Position

- Multiple Coupon Holder:   to control corrosion rates at different “heights” of the fluid.

Coupon Holder can be realized in two different configurations:

when coupon control is performed while the plant is working, and it has to be possible to insert and retrieve the coupon itself. This is the standard situation.

when coupon control has to be realized only when the plant is not working.
