LEAK DETECTOR: TESTO MODEL 550. THIS IS THE 550 AND THE 552 ONLY, NO PARTS OR CONNECTORS WITH THIS ITEM. ONLY CASE AND INSTRUCTION GUIDES. Our employees are knowledgable in a wide array of areas to help you.
This Testo digital manifold kit will measure temperatures and pressure for up to 60 types of refrigerants. It automatically calculates superheat and sub-cooling temperatures. You can connect to the device via Bluetooth to remotely check up on its statistics. The included smartphone application may be used to make reports and email invoices, including statistical reports. It has a rugged, impact-resistant frame and a three-way valve system with three different ports. It weighs 5.5 pounds and measures 12.6 inches in length.
Works great, first time I used it to check the charge on a central air unit in a house I bought.
The unit never seemed to cool enough. The unit was installed some years before I bought the house and the compressor had to be changed. When I connected the Testo 550 to the unit the pressures and temperatures were all wrong. I had to remove quite a bit of Freon to get the unit to work right. Someone had over charged the unit, no wonder why the first compressor went bad. The unit works perfectly now. The Testo 550 was very easy yo use and understand. It has a vast amount of different refrigerants stored in memory. I would recommend this tool to anyone.
Was hesitant to switch over to the digital, but sure am glad I did. This is a great set at a great price. I used field pieces digital gages and be for and didn't like the. The Testo is a lot smaller but packs a lot into the. With all the different Temps they give you makes my job a lot quicker and easier. I would defiantly recommend the Testo 550 a a good budget digital manifold. In my opinion 100 bucks less then field piece but 100 percent better..
The Testo 550 Digital Manifold set works great. I'm able to do a lot more than read the pressures of a system.
Being able to adjust the display to the exact refrigerant that I'm working with allows a faster and more reliable set up of the equipment I'm installing or working on.
