Fluke PV350 – Overview The Fluke PV350 is a compact pressure/vacuum transducer module that turns most digital multimeters (DMMs) into a pressure gauge. It reads gauge pressure up to 500 psi (3447 kPa) and vacuum down to 29.9 in-Hg (76 cm Hg), converting measurements into a 1 mV per unit output. It is corrosion resistant, field-ready, and ideal for HVAC, hydraulic, pneumatic, and lab applications. Key Features Converts a DMM into a pressure/vacuum gauge with 1 mV per psi output Measures gauge pressure up to 500 psi (3447 kPa) Measures vacuum down to –29.9 in-Hg (–76 cm Hg) Accuracy: ±0.25 % of reading ±0.3 psi (pressure), ±0.25 % ±0.5 in-Hg (vacuum) Compatible with industrial gases and liquids compatible with 316 stainless steel Compact and rugged module with field-ready connectors ¼ in. NPT pressure port; includes flare-to-pipe adapter Operates from internal 9 V battery (~300 hours typical use) Technical Specifications Model: Fluke PV350 Pressure Range: 0 to 500 psi (0 to 3447 kPa) Vacuum Range: 0 to –29.9 in-Hg (0 to –76 cm Hg) Accuracy (Pressure): ±(0.25 % of reading + 0.3 psi) Accuracy (Vacuum): ±(0.25 % of reading + 0.5 in-Hg) Temperature Coefficient: add 0.05 % of reading per °C outside 18-28 °C Output: 1 mV per unit (psi, kPa, in-Hg, or cm Hg) Burst Pressure: 1000 psi Max Working Pressure: 500 psi Input Impedance of DMM: ≥ 1 MΩ Power: 9 V alkaline battery Battery Life: ~300 hours typical Housing Material: 316 stainless steel sensor wetted parts Port Connection: ¼ in.
