Alicat PCU - Gas Flow Portable Calibration Unit

  • Three mass flow meters in one portable meter
  • 98+ Preloaded Gases and Gas Mixtures
  • No warm-up time, ready to go in 1 second
  • Combined Turndown ratios of up to 1,000,000:1
  • ±(0.4% of reading + 0.2% of full scale accuracy)

Portable flow calibration with a very wide dynamic range

The Alicat PCU series house three individual mass flow meters in one single battery powered case offering a very large flow range for one single device.

The PCU comes equipped with removable battery pack or a mains powered option.

Each mass flow meter comes supplied with flow totalisers and high accuracy calibrations to +/- 0.4% reading + 0.2% full-scale range.

Each individual mass flow meter is repeatable and accurate and features Alicat’s excellent 10,000:1 turndown ratio, resulting in a combined turndown ratio of up to 1,000,000:1!

Choose three mass flow meters with full scale flow rates from 0.5 SCCM up to 1500 SLPM; we can help scope your requirements as to which three flow meters would be best suited.

Every Alicat device is backed by the manufactures limited life time warranty and ships with a NIST traceable calibration certificate.

RS-232 communications are standard on all PCU devices as well as a copy of FlowVision SC software.

A copy of the FlowVision SC software is included as standard on all PCU devices.
