• What refrigerants does it support?

  This HVAC gauge is compatible with 88 refrigerants, covering A1, A2L, and A2 types including R22, R410A, R32, and R454B. The 16 most common refrigerants are prioritized for quick switching. Built-in A2L low-flammability warning adds safety.

• Is it accurate?

  This gauge delivers ±0.5% FS pressure accuracy from -14.5 to 800 psi, with 10 MPa overload capacity. For better results, always zero the gauge with hoses open to atmosphere before connecting. If readings seem off, re-zeroing usually resolves it.

• How do I zero the gauge?

  Disconnect hoses (keep them open to atmosphere), then long press ZERO button to reset. Do this before each use or refrigerant change. If zeroed under pressure, simply re-zero correctly – the gauge will return to normal.

• Does it come with everything I need?

  Includes a gauge, three hoses, two R410A adapters, and a carry case – ready for home split systems, rooftop units, and walk-in coolers.

  Note: Designed for pressure, vacuum, and leak testing – no temp clamps, so superheat/subcooling is not supported.

• Can it be used for home HVAC systems?

  Yes. This gauge is designed for residential AC, central AC, commercial HVAC, cold storage, and general refrigerant equipment.
