Wisscool Dual Digital Manifold Gauge for 94 Refrigerants — Compact handheld, ±0.5% accuracy, multi-unit readouts

WISSCOOL Dual Digital Manifold Gauge is a portable HVAC manifold that reads pressures and temps for 94 refrigerants, enabling fast, accurate charging and diagnostics.

This compact digital manifold replaces slow analog conversions by offering immediate pressure readouts, selectable refrigerant tables, and temperature references. Designed for HVAC and automotive AC technicians, it consolidates many tools into one durable, battery-powered device for everyday service, commissioning, and maintenance tasks.

Which refrigerants does this gauge support and why does that matter?

The WISSCOOL gauge includes factory tables for 94 refrigerants so you can select the exact refrigerant and get corrected temperature references without manual PT-chart lookups. That reduces conversion errors and speeds up diagnosis and charging on mixed fleets of systems.

• Supports common and modern blends like R32, R454B, R1234yf, R410A, R134a, R22 and many more
• Automatic pressure-to-saturation reference after refrigerant selection
• Eliminates frequent manual PT-chart conversions

How accurate and reliable are the readings?

This digital manifold delivers stable measurements with factory accuracy rated at ±0.5% FS, suitable for routine maintenance, diagnostics, and commissioning. The large LED display and color coding improve readability on the job, while an integrated sight glass helps verify refrigerant flow during charging.

• High-accuracy digital sensors for dependable pressure readings
• Multi-unit display: kPa, mbar, bar, inHg, and psi
• Visible sight glass to confirm refrigerant movement during service

What functions does it include for evacuation and temperature checks?

The gauge supports vacuum checks for basic evacuation verification, letting you monitor negative pressure during pump-down, though it is not a micron-level vacuum gauge. Temperature units switch between Fahrenheit and Celsius so you can cross-check system superheat and subcooling references.

• Vacuum pressure display for evacuation and leak checks (not a micron gauge)
• Switchable temperature units (℉/℃) for compatibility with tech preference
• Useful for basic evacuation verification and service troubleshooting

How does this tool fit into a technician’s workflow?

The WISSCOOL digital manifold streamlines charging and diagnostics by combining pressure measurement, refrigerant selection, and temperature reference in one handheld unit. With auto shut-off and battery operation, it’s built for field use and easy transport between job sites.

• Three-port manifold layout lets you attach hoses for charging, recovery, or testing
• Auto shut-off conserves battery life for longer field use
• Compact form factor reduces the need to carry multiple specialized gauges

Who is this for: Ideal for HVAC technicians, mobile auto AC specialists, and service professionals who work across residential, commercial, and automotive systems and need a single, accurate handheld manifold that handles modern refrigerants. Note: if you require micron-level vacuum measurement for deep evacuation, use a dedicated micron vacuum gauge alongside this unit.
