Operating Guide & Setup
- Insert the included AA batteries and connect the temperature clamp probes to the aux ports on the instrument base.
- Select the required refrigerant profile (e.g. R32 or R410A) using the intuitive push-button menu interface.
- Connect high and low pressure hoses to the brass manifold ports and attach to the service valves of the AC or refrigeration system.
- Observe real-time low-side/high-side pressure, saturation temperatures, and live superheat or subcooling calculations on the dual backlit screen.
- Use the built-in timing mode for system pressure leak decay testing during pre-commissioning.
Engineer Reviews & Feedback
Compiled from marketplace feedback and product research signals.
Upgraded from my trusty old analog set to this digital hvac manifold gauge for heat pump installs in Yorkshire. The superheat calculations are spot on and save me 15 minutes per commission.
Great build quality and super clear screen. Having R32 and R290 profiles built-in makes modern air-to-water heat pump servicing completely hassle-free. Outstanding value compared to Testo.
Ordered on Tuesday, arrived in Scotland on Wednesday morning. Used it straight away on a commercial refrigeration leak check. The pressure decay feature is rock solid.
Very accurate pressure readings and the dual screen backlight is great in dark plant rooms. Only minor downside is I wish it came with Bluetooth app support, but for under £170 it's unbeatable.
Replaced my old Yellow Jacket mechanical gauge with this digital manifold gauge. The temperature clamp accuracy is spot on and F-Gas reporting is so much simpler now.
Decent, rugged piece of kit. Drops into my tool bag nicely and the brass valves feel smooth and robust. Fast delivery from PageGear.
