Constant Pressure Sample Cylinder BP-PD

Constant Pressure Sample Cylinder (

piston cylinder of  constant pressure )

Constant Pressure Sample Cylinders (samplers) are created to ensure the correctness and accuracy of measurement results of liquefied petroleum gas (LPG) and by-products of oil and gas. Constant Pressure Sample Cylinders Cylinders are designed for the preparation of Reference Materials and sampling of unstable gas condensate and LPG samples. BD-PD are made of high quality stainless steel and equipped with magnetic indicator, calibration scale, and gauges on the each value of cylinder. Cylinders are available in capacities of 0.2, 0.5, 1, 2, 4 liters.

Cylinders of 2 and 4 liters certified in accordance with TR CU 032/2011.

 The sampler ensures the stability of the sample composition.
