Sentry ISOLOK API-CA Automatic Sampler

Part #

The Sentry ISOLOK API-CA sampler is an anvil piston instrument (API) cell sampler specifically designed to handle the most demanding hydrocarbon liquid applications. By taking full advantage of all the benefits of bypass or fast loop sampling systems, the ISOLOK API-CA is ideally suited for sampling a variety of liquids, especially crude oil, condensate and mixtures of oil and water. The ISOLOK API-CA sampler is ideal for energized mixing and blending applications.

The pneumatically actuated ISOLOK API-CA sampler optimizes the accuracy and repeatability of hydrocarbon fluid sampling. The sampler offers superior performance and a long life, minimizing maintenance, accessories and service time needed. The sampler’s 180-degree pneumatic actuator and scotch yoke design provide consistent performance over a wide range of air supply conditions and process pressure and viscosities.

The optional diamond-like carbon (DLC) coating protects the unit from abrasion and enhances resistance against H2S, mercaptans, SO2, mercury and more.
