Sentry Saf-T-Vise coupon holders offer ease of use and custom configuration for maximum versatility. The Saf-T-Vise patented locking collet is simple to use and enhances operator safety by safely securing the shaft within the process stream in both low and extremely high pressure conditions. These coupon holders work with a variety of corrosion coupons, including rod (cylinder), flat (strip) single hole, flat (strip) dual hole, and disk, to measure the rate of corrosion within a pressurized process such as a pipeline.

SENTRY SAF-T-VISE COUPON HOLDERS – THE SAFEST CHOICE UNDER PRESSURE
Metal corrosion is inevitable, and has the potential to cause catastrophic pipeline and assets failure, damaging the environment and communities, injuring field operators, and causing costly downtime and waste in productivity. However, corrosion is easy to measure.

Benefits
Saf-T-Vise coupon holders are hand insertable (low pressure) or mechanically insertable (high pressure) into your pressurized system. With a wide range of pressure ratings available, Saf-T-Vise coupon holders are the optimal choice for corrosion monitoring and protecting most pressurized applications. They can be mounted in any orientation with extended insertion lengths of up to 20 feet for hard-to-access application situations. Saf-T-Vise STV-T Series insertion tools are used for mechanically inserting the corrosion coupon rods.
