Digital Manifold Gauges – Bluetooth & Wireless HVAC Tools for Australian Technicians
Digital manifold gauges take the guesswork out of refrigerant service work. Real-time superheat and subcooling calculations, Bluetooth connectivity, app-based data logging, and PDF report generation — all from a tool that fits in your service bag. If you're commissioning systems, doing compliance work, or just want faster, more accurate diagnostics, a digital manifold is a genuine upgrade over analog.
This collection covers digital and wireless manifold gauges from Fieldpiece, Testo, Mastercool, and Robinair, suited to R32, R410A, R134a, R404A, and other common refrigerants.
Why Go Digital?
Automatic superheat & subcooling — calculated in real time from built-in refrigerant tables, no manual lookup required
App connectivity — view readings on your phone, log data, and generate PDF reports for clients and compliance records
Built-in refrigerant library — switch between refrigerant types without swapping gauge sets
Wireless probes — some models connect to wireless temperature clamps for a complete system picture without extra leads
Leak-tight connections — digital manifolds typically use low-loss fittings to minimise refrigerant loss during connection and disconnection

Frequently Asked Questions
Do digital manifolds work with R32?
Most modern digital manifolds include R32 in their refrigerant library and are rated for A2L refrigerants. Always confirm the specific model's compatibility before use on R32 systems.
Can I use a digital manifold without a smartphone?
It depends on the model. Some digital manifolds have a built-in screen and work fully standalone. Others (like Fieldpiece Smart Probes) use your phone as the display. Check the product listing for display details.
What's the advantage of wireless temperature probes?
Wireless clamp probes connect to your manifold via Bluetooth, letting the app calculate superheat and subcooling automatically without you manually entering temperatures. It speeds up commissioning and reduces errors.
