Description
This refrigerant pressure gauge is engineered for precise measurement of both low and high pressure in HVAC and refrigeration systems. It supports a wide range of refrigerants, making it suitable for both residential and industrial servicing applications.
The gauge features a 304 stainless steel case for excellent corrosion resistance and durability, combined with a copper movement (Bourdon tube) for stable and reliable pressure transmission.
Filled with silicone oil, the gauge provides outstanding vibration resistance, reduces internal friction, and ensures smooth pointer movement even under fluctuating pressure conditions.
The polycarbonate (PC) lens offers high transparency and impact resistance, allowing clear readings while maintaining durability in harsh environments.
Additionally, the built-in damping screw minimizes pressure pulsation effects, protecting internal components and improving measurement accuracy.

The EDPS series differential pressure switch is a special type of control switch. It is a kind of switch that controls closing or opening based on the pressure difference between mutual components and relies on electrical signals for information transmission.
Floats are available in 1–4 pieces (optional,or more), and the rod length can be customized.
Notes:Float switches cannot directly control solenoid valves, high-power relays, AC contactors, etc. A small relay HH45P is required for transition.
