Pressensor is a Bluetooth enabled device that attaches to your espresso machine. It measures and records the pressure of the water flowing through the coffee grounds during the extraction process. The data is then sent to a mobile app, which allows you to view and analyze the pressure profile in real-time, and to save and compare different extraction profiles.

The data is then sent to a mobile app, which allows you to view and analyze the pressure profile in real-time, and to save and compare different extraction profiles. This technology helps you to understand the impact of variables such as grind size, dose, and tamping on the final flavor of your espresso, and to make small adjustments that result in a noticeable improvement in taste, aroma and overall quality of your coffee.

Installation is easy: you just remove the screw from the head and screw in the sensor. The sensor operates with a standard 2032 battery. (A good quality battery is recommended) The device operates in the pressure and temperature range of a normal coffee machine. Pressure peaks are tolerated up to 15 bar.
