The PIC Gauges 100 Series 102D-204 is a 2" dry utility pressure gauge with a 1/4" Male NPT center back (lower back) connection, built for dependable everyday service in industrial, commercial, and OEM air, fluid, and gas applications.
Which range should you choose?
Pick the range type that matches what your system does:
- Pressure (e.g. 0–100 PSI): Positive pressure only — what almost every air-compressor and shop-air job needs.
- Compound (e.g. 30 inHg vacuum to 100 PSI): Reads both vacuum and positive pressure on one dial — for systems that pull suction and also build pressure.
- Vacuum only (0 to 30 inHg): Suction / negative pressure only.
What does "inHg" mean? It stands for inches of mercury — the standard unit gauges use to measure vacuum, meaning pressure below normal atmospheric pressure (in other words, suction). 0 inHg is ordinary atmospheric pressure, and about 30 inHg is a near-complete vacuum — roughly 14.7 PSI of suction. So a gauge marked "30 inHg" reads the entire vacuum range, from no suction down to full vacuum. (By comparison, PSI measures pressure above atmospheric.)
