• The ability to connect the liquid sampler close to the sample point ensures optimal retrieval of a representative liquid sample.
• The DPM type sampler in on/off configuration allows the product to flow directly into the sample bottle via an angled two-way valve at a recommended maximum operating pressure of 8 bar.
• This liquid sampler offers one-handle operation, providing safety for the operator and zero emission.

• The ability to connect the liquid sampler close to the sample point ensures optimal retrieval of a representative liquid sample.
• The DPM type sampler in on/off configuration allows the product to flow directly into the sample bottle via a straight two-way valve at a recommended maximum operating pressure of 8 bar.
• This liquid sampler offers one-handle operation, providing safety for the operator and zero emission.

• The ability to purge the sample point ensures optimal retrieval of a representative liquid sample.
• The DPM type sampler in system purge configuration allows the product to flow continuously through the three way valve ensuring a fresh sample at a recommended maximum operating pressure of 8 bar.
• This liquid sampler offers one-handle operation, providing safety for the operator and zero emission.

• The ability to back purge the sample point ensures optimal retrieval of a representative liquid sample.
• The DPM type sampler in back purge configuration allows a gas to purge the sampler prior to sampling ensuring a fresh sample at a recommended maximum operating pressure of 8 bar.
• This liquid sampler offers one-handle operation, providing safety for the operator and zero emission.

• The ability to purge the needle assembly ensures there is no residue or build up in the needle assembly after retrieval of a representative liquid sample.
• The unit offers the possibility to purge the bottle with an inert gas prior taking a sample.
• The DPM type sampler in needle purge configuration allows purging through the needle assembly at a recommended maximum operating pressure of 8 bar.
• This liquid sampler offers one-handle operation, providing safety for the operator and zero emission.
