Evacuating AC/R systems: the testo 552 Digital Vacuum Gauge is for the evacuation of heat pumps, air conditioning, and refrigeration systems. The innovative testo 552 utilizes a sensor that, unlike the competition, requires no cleaning and is not affected by contamination. Never worry about a dirty sensor causing false readings. Trust your testo 552 to always be accurate. Documenting measurements: When you use the testo 552 in combination with the testo 570 digital manifold, you can save the testo 552's measuring values or display them directly on a laptop via the optional EasyKool software. Complying with manufacturer's specifications: Some manufacturers specify the desired micron lower limit that must be achieved to evacuate their air conditioning systems and how long this pressure must be maintained. Compliance with these specifications is simple and easy thanks to the flexible setting of the alarm threshold in the testo 552. Ensuring dehumidification: The testo 552 not only measures pressure, but also gives the water evaporation temperature associated with it. In addition, it measures the ambient temperature and displays the temperature difference. This means you can quickly check whether the moisture in the system is evaporating and dehumidification is progressing properly.

Worth its weight in gold
Awesome product, and powerful as well. The seller as well, thank you for a good delivery!pick your favorite brand, I have a few of them myself, one of which being testo. As far as i’m concerned, it’s worth its weight in gold. Using the app and seeing the graph and actually watching the 4 data points (water evap temp, OAT, microns, and temp differential) being plotted, seeing where it’s about to stall out, for me being a very visual person and technician, this is my end all be all.This isn’t just a “single use of product” review either, in the very short amount of time that i have owned this, the manual makes it very clear how to use unit to full potential, and evacuating about 5 units now, i can firmly say that (let’s forget the brand for a moment), this product does what it says it will do, and does it well.ALSo, it uses a pirani sensor, as tech support told me, it’s more accurate in low microns than the absolute sensor. Just so that’s clear.

Great vacuum gauge
I love this gauge. It looks good feels good in your hand feels well-built. Works like a champ no problems with it at all. I use it at least once a week sometimes twice three times.

In-line design allows simpler connections.
Very accurate and you need to remember this measures PSIA without a need to ever clean the sensor.

There is a learning curve with this guage your owners manual is your best friend I suggest linking it to you're phone and setting the settings from there. I have had a chance to compare to field peace frankly field piece is more user friendly but testo gives you more info but you half to know how to get it out of a testo.
