Bottomhole Sampling Positive Displacement Sampler One Phase Sampler Sampler Clock Digital Transfer Gauge	The Bottom Hole Positive Displacement Sampler PDS provides representative sample of well fluid which can be transferred to sample bottle without using mercury. The OPS One Phase Sampler provides representative sample of well fluid which can be transferred to sample bottle without using mercury. The Samples are maintained in single phase when brought to surface. The Sampler Clock has been designed to activate the Leutert bottom hole samplers PDS and OPS. Samplers with different pressure ratings can employ the same clock. The Digital Transfer Gauge is used to ascertain that no pressure drop below the bubble point has occurred during the transfer of a Single Phase Bottom Hole Sample.
