General Description; Specifications - Sentry Cobra M Installation, Operation & Maintenance Manual

General Description

Read these instructions completely before proceeding to assemble, install or operate this machine. This machine should
be installed, operated and serviced by qualified individuals. Follow proper local, state and federal regulations for proper
installation and operational requirements.
Designed for longevity, the Sentry® Cobra M liquid sampler boasts a variety of unique features that makes it simpler to
install and easier to operate. Made of stainless steel or other exotic materials, the sampler meets the highest standards
of quality and reliability. All of our Cobra M units use the Cobra-designed sampling valve that allows throttling
and control of sample flow. The Cobra needle design provides ample time for air and other gases to be expelled.
Representative samples are assured by following step-by-step procedures printed on the system.
The Cobra M sampler includes a multi-turn handle that permits precise flow control, while a full bore flow path ensures
that no pressure is lost while the sample is being taken. The standard units come with our special coaxial needle
system, the risk of bent or broken needles is reduced dramatically. The Cobra sampling valve has been specifically
designed for process sampling, and protects against contamination to ensure the safety of the operator while
maintaining the integrity of every sample taken.
