It has all the measuring functions you need for evacuating refrigerant systems and heat pumps and is built to last and tough enough to take the odd knock.Via a Bluetooth interface, the testo 552 connects with the testo Smart App on your smartphone or tablet. This allows you to monitor the absolute pressure reached during the evacuation conveniently and wirelessly. In addition to this, the measurement results can be quickly documented in the App and sent by e-mail.<\/p>\n<div>\n<h3>The testo 552 digital vacuum gauge \u2013 areas of application<\/h3>\n<p>Evacuating is one of the most important steps when it comes to installing or restarting refrigerant or air conditioning systems: foreign gases, moisture and oils have to be removed properly. That\u2019s when the absolute pressure of a system needs to be measured.<br \/>\nAnd that\u2019s exactly what the testo 552 digital vacuum gauge is designed to do: the meter provides you with highly accurate information regarding the dehumidification status of the system and is able to measure even the smallest of absolute pressures absolutely reliably. This means that you are always able to observe manufacturer specifications. A visual alarm warns immediately when a threshold has been exceeded.<br \/>\nAnd because the digital vacuum gauge is IP42 rated (water resistant and dirt proof), it is virtually impervious to moisture and dirt.<\/p>\n<\/div>\n<h3>Includes<\/h3>\n<p>testo 552 digital vacuum gauge with Bluetooth\u00ae, two AA batteries.<\/p>\n<h3>Absolute Pressure<\/h3>\n<div class=\"mx-auto max-w-[706px] pb-6\">\n<div class=\"mb-5\">\n<section class=\"mt-8 max-w-[calc(100vw-40px)] [&amp;:first-child]:mt-4\">\n<div class=\"overflow-auto\">\n<table class=\"w-full text-left text-warmGray-600\" style=\"border-style: solid;
