Cobra FV

The Sentry Cobra FV sampler allows an operator to safely and efficiently collect a fixed volume of high-pressure liquids. The Cobra FV sampler is specifically designed to ensure a high quality fixed volume sample through the simplest and most reliable process possible. The sample valve allows each sample to be extracted quickly and easily while simultaneously purging the assembly with nitrogen, thus ensuring the cleanest possible sample is taken. The sampler can also be adapted to facilitate automatic sample extractions or composite samples.

The Cobra FV sampler offers the greatest level of reliability and ease of use. Each unit uses the Cobra-designed sampling valve, facilitating easy regulation by ensuring sufficient time for air and other gases to be expelled. A variety of accessories are available—from needle purge to cooling coils—so that the sampler can be customized to suit the specific requirements of the application.
