The PIC Gauges 201L is a liquid-filled (glycerin) industrial pressure gauge built for applications where vibration and pulsation would otherwise destroy a dry gauge. The glycerin fill dampens needle flutter for a steady, readable indication and extends service life, while the one-piece stainless steel case and bezel resist corrosion and washdown environments. Part of PIC's PRO 200 Series, it reads in a dual PSI/BAR scale and is offered in vacuum, compound, and pressure ranges from 30 inHg up to 20,000 PSI.
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.)

Applications
Air compressors, hydraulic and pneumatic systems, pumps, water treatment, HVAC, and general industrial equipment subject to vibration or pressure spikes.
The glycerin-filled PIC 201L delivers reliable, vibration-resistant pressure measurement in a corrosion-resistant stainless steel case. With a 2.5" dual-scale dial, 1/4" NPT lower-mount connection, and ranges spanning vacuum to 20,000 PSI, this gauge is a dependable, value-priced choice for compressed air and fluid-power service.
