PCU–Gas Flow Portable Calibration Unit
Portable flow calibration with a very wide dynamic range
Order Directly from Alicat
When a single flow meter won’t cover all of your calibration needs, consider using a portable calibration unit (PCU). Alicat’s PCU is a secondary calibration standard that combines up to 3 high-accuracy flow meters of varied ranges (max 500 slpm) with totalizers into a rugged industrial carrying case for go-anywhere portability. PCU’s can be powered by 4 AA batteries or the included AC cable and include a copy of Alicat’s Flow Vision SC™ software.
- Versatile. Quickly calibrate multiple instruments across a combined turndown range of up to 100,000:1 (for example 5 sccm – 500 slpm) with easy push-connect fittings or optional compression fittings.
- Accurate. Measure live flow rates and flow totals with NIST-traceable accuracy (as good as 0.5% reading) for a variety of gases down to 1/1000th of full scale, or define your own gas composition with COMPOSER™.
- Rugged. The PCU houses the flow meters within a rugged hard case and can withstand drops if they should occur.
PCU’s are also available in our “Whisper” configuration with low pressure drop (PCUW series) and 316L configuration for use with corrosive gases (PCUS series).
Part numbers below are just a few examples of PCU range combinations. Any 3 flow meters with ranges up to 500 slpm may be included in a standard PCU. Alicat’s PCU series is suitable for use with non-corrosive gases.
