PGU series and PGC series pressure gauges are designed for use in a wide range of applications, from bulk gas distribution to process tool applications. Their accuracy is in accordance with ASME B40.1 and dial sizes of 50 mm (2 in.), ± 2% / 1% / 2% of span (ASME B40.1, Grade A, EN 837-1 Class 2.5, JIS B7505 Class 2.5), and 40 mm (1 1/2 in.), ± 3% / 2% / 3% of span (ASME B40.1, Grade B, EN 837-1 Class 4, JIS B7505 Class 4), are available.

PGU series gauges are UHP “clean” for semiconductor gas applications, in accordance with SEMI/SEMATECH and are cleaned and packaged in a class 100/10 cleanroom and have 316L VAR end connections.

PGC series gauges are assembled, cleaned and packaged in a class 100 cleanroom and have 1/4 in. NPT end connections.
