The Stewarts Chemical Seal Pressure Gauge (0–2.5 BAR, 100mm, ½” NPT, Bottom Connection) is a precision-engineered instrument built for accurate and dependable pressure measurement in corrosive or harsh process environments.

Constructed with 316 stainless steel case and wetted parts, this gauge delivers superior resistance to corrosion, chemical attack, and contamination, ensuring long operational life even in the most demanding industrial settings. The chemical seal diaphragm isolates the sensing element from the process media, maintaining measurement integrity and preventing damage.

With a 0–2.5 BAR pressure range and 100mm dial, it provides clear, linear readings ideal for low-pressure applications in process control, fluid handling, and chemical systems. The bottom-mounted ½” NPT connection ensures secure installation and easy accessibility.
