The Stewarts 100mm Chemical Seal Pressure Gauge (½” NPT Bottom Connection) is designed for accurate and dependable pressure measurement in demanding process environments. Engineered with a 316 stainless steel body and wetted parts, this gauge provides superior corrosion resistance, making it ideal for applications involving aggressive chemicals, viscous fluids, or high-purity media.

With a dual pressure scale of 0–150 LBF/IN² (PSI) and 0–10 BAR, the gauge delivers clear, linear readings for consistent performance in industrial systems. The chemical seal diaphragm isolates the sensing element from process media, protecting the instrument and extending its operational life.

The bottom connection design ensures easy panel or surface mounting, while the 100mm dial offers excellent readability, even in low-light or high-vibration conditions.
