Testo 550s Digital Manifold

The Testo 550s Digital Manifold featuring incorporated Bluetooth, is an ergonomically designed device with a large easy-to-use display. Exceptionally compact and featuring a 2-way valve block, the 550s is ideal for commissioning, servicing and performing maintenance on refrigeration systems and heat pumps. The automatic Bluetooth connection provides the user with the ability to measure vacuum and temperature wirelessly & efficiently. The bigger screen with dot matrix technology aids user in evaluating results by showing more values simultaneously and creating flexible graphics, such as an analogue look for fast and easy pressure values.

For tasks with crucial system parameters, the 550s Digital Manifold features stored programs which provide the user with clear operational guides. Assisting with measurements, these programs automatically determine numerous variables such as superheating, sub cooling, cooling/heating capacity and more. Test menu sequences are included for vacuum, target superheat, pressure leak test and discharge line temperature. Refrigerant favourites are also now saved internally for easy selection, with the list constantly updated by the free app.

With an improved operating concept and fewer buttons, the intuitive Testo 550s guarantees continuously high performance. Due to a direct and easy wireless connection up to 150m, Testo Smart Probes remain consistently connected to your device. Effortlessly link these Testo probes for temperature, pressure and humidity readings. The robust housing of the 550s covering an internal metal frame boasts an IP54 protection rating, ensuring the durability needed for difficult workspaces.

Testo 552i Smart Probe Vacuum Gauge

The Testo 552i Smart Probe Vacuum Gauge is a robust device ideal for quickly and easily identifying vacuum. Measure vacuum wirelessly though a single service port and avoid unnecessary leaks, utilising the probe's integrated 45˚ angle for simple installation. Rated IP54, this Smart Probe automatically connects to the free Testo Smart App or Digital Manifold via Bluetooth with a range of up to 130m. Results are displayed graphically either in app or on the manifold digital display screen.

Testo Smart App

Easily avoid measurement errors by utilising the Testo Smart App, fully compatible with all Bluetooth-capable Testo measuring instruments. Featuring menus which provide optimum support for configuring and capturing measurements, this free app is suitable for jobs involving refrigeration systems and heat pumps. Manage a list of favourite refrigerants within your tablet or smartphone and the app will automatically create refrigerant-specific calculations of evaporation and condensation temperature. Values are presented clearly and reports can be created on-site including photos, PDF & CSV files. Automatically updated, this app is free for both iOS & Android and is easy to synchronise with Testo DataControl PC software.

Testo DataControl Software

Including an intuitive user interface, the Testo DataControl Software provides the user with all the information available in a single click.
