The Alicat PCU integrates three Alicat Laminar Mass Flow Meters into an industrial briefcase that can be taken anywhere in the world to verify the operation of flow equipment. Unlike other current secondary standards, the PCU is fully self-contained and does not require any additional support equipment or line power. The PCU also has on-board digital output to send flow data to a laptop or other computer system.
The PCU can be plugged into wall power or it can be powered by two standard 9V batteries. The unit will alert the user to replace the batteries when power falls below a minimum threshold via a bright led indicator. The ranges of the flow meters are specified by the end user while ordering the PCU.
Alicat Portable Calibration Units are available with these features:
• Low, Medium, and High Range Displays of Mass Flow, Volumetric Flow, Pressure & Temperature
• Multi-drop RS-232 I/O communications packages for simultaneous data acquisition from all three meters.
• 20 pre-set selectable gas calibrations and 10 pre-set gas mix calibrations (specific gas mixes and calibrations available)
• Alternate and adjustable STP to simplify comparisons to other flow devices
• High accuracy calibration of +/- (0.4% of reading + .2% of full scale) (on full scale flow ranges from 5 SCCM to 500 SLPM)
• Integrated totalizer for tests that require long term averaging
• All of Alicat’s products carry the CE marking and are NIST traceable
