Ashcroft Q-4907 Pneumatic Temperature Compensated Test Gauge delivers precise 0–200 psi readings in pneumatic systems, using a temperature-compensated movement to minimize thermal error across ambient and process temperatures. Designed for calibration and testing tasks in maintenance shops, laboratories, and pneumatic test benches, it provides a reliable pressure reference for compressed-air lines and pneumatic equipment. Verified specifications include a 0–200 psi range and a temperature-compensated movement, a feature Ashcroft describes as reducing temperature-related drift in gauge performance.
