Promethion CM-8 Flow and Calibration Multiplexer

Features

  • Automated gas switcher with calibration gas inputs
  • Pressure monitoring to avoid running out of calibration gas during calibration
  • SableHD™ technology ensures an industry leading resolution of 0.001 ml/min
  • Airstream and pressurized calibration gas range of 0-5 SLPM
  • Sample flow range of 0-2.5 SLPM

Description

The Promethion CM-8 Flow and Calibration Multiplexer extends the utility of an automated gas switching system to include the calibration gas inputs.   The CM-8 offers secure high pressure connections for three calibration gas inputs and up to four sample gas inputs, as well as a reference gas input for baselining.  Unlike conventional gas switchers, the CM-8 offers pressure monitoring of the calibration gas inputs, thus eliminating the possibility of running out of a calibration gas while in the process of calibration.  Communication and control of the CM-8 is through Sable’s SableScreen software package utilizing Sable’s unique SableBus direct digital data transfer protocol.
