Your guide to the testo refrigeration kit

Technicians responsible for maintaining and repairing A/C and refrigeration systems can find it difficult to do their job without the right measuring instruments.

After all, these systems are often prone to slight temperature fluctuations and pressure changes which can be troublesome to detect without sensitive equipment. This is where the advantages of the testo smart refrigeration set, the testo 552 and the Smart Probes app come into play.

With this unique and capable set of tools, A/C and refrigeration management becomes much easier.

A smarter approach – the testo smart refrigeration set

So what is this set? Basically, it’s a combination of four testo instruments that are capable of measuring high-side and low-side pressures – along with the temperatures – of A/C and refrigeration systems. There are two testo 115i instruments, two testo 549i instruments and a Smart Case, batteries and calibration protocol.

Both of these instruments are easy to set up, even for those new to testo tools. Once they’re operational, technicians can then easily use the tool at the temperature measuring point or pressure connection. Wireless connection capability to a smartphone or tablet means there’s little difficulty when working on widely spaced measuring points.

To further improve usability, these tools require no hoses when taking measurements. It’s a feature that helps to significantly reduce loss of refrigerant. Finally, the Smart Case makes it easy to transport these instruments wherever they’re required.

So, the testo smart refrigeration set includes a number of useful tools and allows technicians to do their jobs with a high degree of accuracy, but it is possible to add additional functionality.

Combining with the testo 552

A high-precision digital vacuum gauge, the testo 552 brings functionality above and beyond that found in the smart refrigeration set. With this tool, technicians can evacuate refrigerant systems and heat pumps. What’s more, the instrument is enclosed in a rugged housing that’s designed for even the toughest work environments.

Interestingly, this is the only vacuum gauge available on the market.

It’s important to use an instrument with the capabilities of the testo 552, as evacuating is a crucial step when installing or even restarting an A/C system. Over time, foreign gases, moisture and even oils can make their way inside, and need to be removed.

The testo 552 also has an IP42 rating, 400 hours of battery life and enough power for 100 days of continuous operation. Combined, these two features mean the testo 552 can slot into a tool belt and be taken wherever it’s required.

Taking advantage of a powerful app for smartphones

This device also extends functionality beyond the device, with the ability to integrate with a mobile application – the testo Smart Probes App. When using the instruments in the testo refrigeration kit, the tools can transmit measurement data wirelessly across to the app. Then, technicians can view the measurement data with ease in either a table or chart format and send the data in a PDF or Excel file to a computer.

Other functions include time and multi-point mean calculation and a pressure drop test further adds to the suite of tools available.

The testo Smart Probes app also works on both smartphones and tablets.

Smarter instruments are the key to making A/C and refrigeration maintenance an easier task, so reach out to testo today to learn more about the various instruments and kits available.
