R744 Gauge

The R744 Gauge series is purpose-built for R744 (carbon dioxide, CO₂) refrigerant systems. Its black gauge body is paired with a dedicated protective sheath for enhanced durability, capable of withstanding the high operating pressures typical of R744 systems to ensure safe, stable operation. Each set is equipped with a gauge specifically calibrated for the pressure range of R744 refrigerant, ensuring accurate and reliable readings.

As eco-friendly refrigerants gain traction industry-wide, R744 — a natural refrigerant with a low global warming potential (GWP) — is drawing increasing attention. Our R744 Gauge series was developed specifically to meet this emerging demand, and is widely used for diagnostics and maintenance of CO₂-based refrigeration systems in commercial refrigeration and automotive A/C applications — a professional solution aligned with the industry's shift toward greener refrigerants.
