The Acravac Plus utilizes a proprietary Pirani sensor – the most accurate sensor in its class. Pirani sensors use the Thermal Conductivity Principle of vacuum measurement, they are more accurate and cover a wider range compared to conventional measuring technologies.

It has an easy to read digital display in microns, pascal and millibar. It displays the actual reading of the vacuum level throughout the entire evacuation process from the atmosphere (760,000 microns) down to 1 micron, so a leak is immediately visible. The Acravac Plus also has an automatic shut off and stores the last reading for easy retrieval upon startup.

The gauge incorporates several innovative features for unsurpassed performance. Like its predecessor, it uses a Pirani sensor for greater accuracy and the ability to measure the entire vacuum process, from atmosphere down to one micron. The user will know instantly if the connections are vacuum-tight.  An industry-first filter protects the sensor from oil and other contaminants for more accurate readings. Quick calibration allows the user to adjust the Acravac for slight variations in atmospheric pressure at the user’s specific geographic location to ensure greater accuracy.

The extended battery life offers up to 45 hours of use from just one 9 volt battery, that is three times the life of the previous Acravac. To maximise battery life, the Acravac shuts down after 60 minutes and saves the last reading for display upon the next startup
