Request Information
  • The ability to purge the sample point ensures optimal retrieval of a representative liquefied gas sample.
  • The S32-LG type sampler in system purge with additional safety expansion cylinder provides a system purge in addition to sampling in a sample cylinder.
  • The sampler offers the ability to depressurise the quick connect couplings before disconnecting the sample cylinder.
  • This liquefied gas sampler provides one-handle operation by multiple valves. Furthermore, it offers 100% filling rate.
  • The main cylinder is equipped with an additional safety expansion cylinder.
  • Should pressure build-up occur in the main cylinder, the relief valve opens to the safety cylinder.
  • These features ensures sample accuracy, safety for the operator and the possibility of zero emission.
  • This sampler type is suitable for liquefied gas and liquid with high vapor phase.
