The VSR-USB with DN 16 ISO-KF connection is a wide range vacuum transducer that measures from 1500 torr to mid -5 torr. It combines an innovative Piezo sensor and Thyracont-patented miniature Pirani sensor technology in combination to achieve this wide measurement range with excellent accuracy.
It offers a winning combination of small size, orientation flexibility, low power consumption of less than 0.3 w, can be baked up to 125 degrees C with the cable removed, and provides a blazing fast response time. All that?s required to use it is a USB cable.
Due to its low power consumption, the VSR-USB can be powered by an Android smartphone and the pressure displayed using the?free Thyracont VacuSniff app.
