Overview
The Ralston LC20 is a digital pressure field gauge. Ralston describes it as a robust device that measures and displays pressure on a large backlit screen, shows high and low values, switches between 15 engineering units (or custom units), and works with the included FieldLab Desktop PC software for calibration, testing, and live viewing.
Compared with the Ralston LC10, the LC20 datasheet lists tighter accuracy (±0.1% vs ±0.25% of full scale) and an ISO 17025 accredited calibration certificate.
