Notify me when its in stock• The Testo 550s smart digital manifold set is a Bluetooth-enabled measuring device with a 2-way valve block, used for commissioning, maintenance, repair, and inspection of air conditioning systems, refrigeration systems, and heat pumps.
• This digital manifold is used for performing multiple tasks on refrigeration systems and heat pumps.
• The Testo 550s features built-in measurement modes for AC + Refrigeration, Evacuation, Leak Test, Target Superheat, Compressor Test (DLT), and Delta T measurements—all in one device.
• Its most prominent feature is the ability to connect and control other smart probes from a single device and software interface.
• Another key feature is the ability to perform a temperature-compensated leak test.
• The Testo 550s manifold includes both numerical and graphic bar display modes.
• The set includes 2 clamp-type Testo 115i temperature probes.
• The Testo 115i smart probe is used for tasks such as differential temperature measurement, discharge line temperature, and suction line temperature readings.
• In AC + Refrigeration mode, 90 pre-installed refrigerant types are integrated into the device, allowing you to select the refrigerant and take more accurate measurements.
• Thanks to automatic updates via the Testo Smart App, you always have access to the latest refrigerants.
• Optionally, other probes like Testo 552i, 605i, 905i, and Mini-DIN temperature sensors can also be connected.
• The Testo 550s’ 2-way valve block allows for easy monitoring of both low and high pressure.
• The blue valve actuator indicates low pressure; the red one indicates high pressure.
• Pressure and temperature values on the device can be uploaded and adjusted.
• You can pair the digital manifold to your phone or tablet via Bluetooth and monitor the readings in real time, while also saving them.
• Saved data can be sent directly via email in PDF or CSV format.
• System requirements to use the device on mobile or tablet are: iOS 11.0 or later, Android 6.0 or later, and Bluetooth 4.0 or higher.
• Since the Testo 550s calculates superheat and subcooling simultaneously, it eliminates manual calculation errors.
• Features Auto Tfac (Automatic Temperature Compensation Factor).
• This means a surface compensation factor is configured to reduce measurement errors in main applications.
• After completing pressure measurements, if the values remain on the graphical or numerical display, open/close the valve actuators or hold the up arrow to reset the pressure.
• The Testo 550s can be easily used in dark environments thanks to its illuminated LCD screen.
• You can adjust the backlight duration in the settings to 10, 30, 60 seconds, or always on.
• Additionally, from the settings, you can change units of measurement, display brightness, auto shut-off, and more.
• Remote measurement monitoring: You can monitor readings from your smartphone/tablet without standing next to the manifold. Has up to 20-meter (open space) range.
• View measurement data in graphical or numerical format on your smartphone/tablet.
• Convenient documentation functions: Use the mobile app to save results and email reports in PDF or CSV format. If you've taken a photo of the measurement location with your phone/tablet, it can be added to the report.
• Refrigerant updates: Easily update refrigerants through the mobile app.
• The mobile app is available for both Android and iOS. Once installed, the manifold and smart device connect via Bluetooth automatically.
• Fast and accurate results: Two temperature-compensated pressure sensors provide precise low/high pressure readings, and automatically detect evaporation and condensation temperatures.
• Two ports for attachable temperature probes for simultaneous superheat and subcooling calculation.
• Includes 2 smart Testo 115i temperature probes for reliable surface temperature readings when clipped to pipes, wires, etc.
• No need to switch refrigerant hoses thanks to automatic heat pump mode.
• Stores up to 90 refrigerants: all major refrigerants in one device (can be updated via mobile app).
• Also includes features like differential temperature display and temperature-compensated leak test.
• First, power on the Testo 550s digital manifold and perform a simple setup.
• From the menu, set Bluetooth and Advanced Bluetooth to "ON", then confirm.
• Hold down the button on each of the included Testo 115i temperature sensors to power them on.
• Yellow blinking LEDs indicate the probes are searching for the device.
• Once LEDs turn green, the probes are successfully connected to the Testo 550s.
• The Bluetooth icon at the top right shows the number of connected devices.
• Download and install the Testo Smart App from Play Store (Android) or App Store (iOS).
• When you open the app, the Testo 550s and all connected probes will appear automatically.
• The app display automatically adjusts based on the selected measurement mode on the manifold.
• Your mobile device allows full access to reporting and data logging functions.
