Ashcroft 436-36 InHg-30-0-2-1-2HK Pressure Gauge

Ashcroft 436-36 InHg-30-0-2-1-2HK Pressure Gauge is a vacuum-capable instrument designed to measure negative pressure from -30 inHg to 0 inHg. It features a 2.5-inch dial for clear readability and a Hansen coupling (2-HK) rear connection, enabling secure, compatible installation with standard vacuum fittings. This model sits in Ashcroft’s 436 family of gauges, optimized for reliable indication in low-pressure vacuum applications such as process lines, exhaust systems, and laboratory vacuum setups where monitoring of negative pressure is critical. The compact dial size and robust Hansen coupling provide practical fitment in tighter installations while delivering steady, interpretable readings across the specified range for accurate monitoring and control of vacuum environments.
