Smart Probes Refrigeration Set

A. Product Overview

The Testo Smart Probes AC and Refrigeration Test Kit, order number 0563 0002 02, is a compact professional measuring solution for refrigeration engineers, HVAC technicians and air conditioning service professionals.

The kit contains:

• Two Testo 549i wireless high-pressure measuring instruments
• Two Testo 115i wireless clamp thermometers
• Testo HVAC softcase
• Batteries
• Calibration protocol

The Testo 549i probes measure refrigerant pressure directly at the system connection, while the Testo 115i clamp thermometers measure pipe surface temperature. Both instruments transmit measurement data wirelessly to a compatible smartphone or tablet through Bluetooth.

The Testo Smart Probes App can display pressure and temperature readings, automatically calculate evaporation and condensation temperatures, and support application-specific measurements such as superheating, target superheating, subcooling, heating performance and cooling performance.

More than 80 commonly used refrigerants are stored in the app, with refrigerant updates available when required. The hoseless connection method also helps reduce refrigerant loss during system testing.

B. Working Principle

The Smart Probes Refrigeration Set works by measuring refrigerant pressure and pipe temperature simultaneously at the high-pressure and low-pressure sides of a refrigeration or air conditioning system.

The two Testo 549i pressure probes are connected directly to the system pressure ports. One probe can be installed on the low-pressure side and the other on the high-pressure side. Because the probes connect directly without conventional refrigerant hoses, the setup is quicker and refrigerant loss is reduced.

The two Testo 115i clamp thermometers are attached to the refrigerant pipes. The clamp sensors detect the surface temperature of the suction and liquid lines without requiring permanent installation.

All four Smart Probes transmit their readings through Bluetooth to the Testo Smart Probes App. The app combines the pressure and temperature measurements and automatically calculates important refrigeration parameters such as:

• Evaporation temperature
• Condensation temperature
• Superheating
• Target superheating
• Subcooling
• Heating performance
• Cooling performance

The readings can be displayed as numerical values, tables or charts. Technicians can also create measurement reports, add photographs and comments, and send reports by email in PDF or Excel format.

C. Why It Is Used

The Testo Smart Probes Refrigeration Set is used to improve the speed, accuracy and convenience of refrigeration and HVAC system testing.

Refrigeration System Commissioning

The kit helps technicians verify whether a newly installed refrigeration or air conditioning system is operating according to the required pressure and temperature conditions.

Superheating and Subcooling Measurement

Automatic superheating and subcooling calculations help determine whether refrigerant flow and refrigerant charge are suitable for efficient system operation.

Fault Detection

Pressure and temperature readings can help identify problems such as:

• Incorrect refrigerant charge
• Restricted refrigerant flow
• Faulty expansion valve operation
• Evaporator performance problems
• Condenser performance problems
• Abnormal suction pressure
• Abnormal discharge pressure
• Inadequate cooling or heating output

Low Refrigerant Loss

The hoseless design allows the Testo 549i probes to connect directly to the refrigeration system, reducing the quantity of refrigerant lost during testing.

Wireless Measurement

Bluetooth communication allows technicians to view readings from multiple measuring points on one smartphone or tablet. This is especially useful when the measuring points are widely separated.

Digital Documentation

The Testo Smart Probes App allows measurement data to be recorded, analysed and converted into professional service reports. This helps maintain proper commissioning, maintenance and customer service records.

Portable HVAC Testing

The compact probes and protective HVAC softcase make the set easy to carry between installation, service and maintenance locations.
