Enraf Tanksystem’s HERMetic Sampler is designed for restricted or closed gas tight sampling of liquids or chemicals, which present a fire-, health- or air pollution hazard.

The closed gas tight type of sampler avoids a pressure release from the tank and exposure to fumes during operation.

One ball valve has to be permanently installed on each tank to permit connection of various type of HERMetic equipment, like portable level gauge, pressure gauge or sampler depending on the needs of the various customers.

Most samplers can be supplied with specific sampling bottles. Four different sampling bottles are available to permit different kind of sample: Zone bottle, Spot bottle, Running bottle and Bottom bottle.

• The Zone bottle allows sampling of the upper level inside the tank.
• The Spot bottle allows sampling at a determinate height.
• The running bottle allows sampling all along the displacement of the bottle inside the tank.
• The Bottom bottle allows sampling of the tank bottom.

The sample is taken by a vertical move of the bottle inside the liquid. The bottle is linked with a graduated tape.

A reading window allows monitoring the bottle location.

After sampling, the liquid can be transferred into a laboratory bottle through a transfer valve.

The transfer of the liquid from the sampling bottle to a laboratory bottle occurs by gravity or by over pressure of the upper chamber of the sampler.
