Description
The EM700 Series Inclined Tube Red Oil Micro Differential Pressure Gauge is a high-precision, non-powered mechanical instrument engineered for measuring low air and non-corrosive gas pressures. Built with a precision-molded ABS housing and leak-proof ultrasonic welding, it utilizes an inclined column design to physically magnify minute pressure variations. Filled with specialized low-volatility red gage oil (specific gravity 0.826), it delivers clear, continuous, and explosion-proof readings without requiring electrical power or frequent fluid refills.
Ideal for HVAC filter monitoring, cleanroom pressure tracking, and duct airflow velocity measurement, the EM700 operates reliably across -10°C to 60°C. It features an integrated overpressure safety reservoir to prevent fluid loss during pressure surges, along with a zero-adjustment knob and built-in leveling bubble for effortless installation and precise calibration.
