BOOKOO Espresso Monitor Product Manual

The BOOKOO Espresso Monitor (EM for short) is a wireless pressure sensor device designed to monitor real-time pressure in coffee brewing. With this device, you can generate extraction curve graphs in a mobile application to obtain references for optimizing coffee extraction.

EM can also be paired with the Coffee Bluetooth Electronic Scale to obtain additional data such as flow rate, liquid weight, and pressure. We recommend using the BOOKOO THEMIS MINI coffee scale for better data processing results, and it is also compatible with Acaia and Felicia smart Bluetooth scales.

Efficient sharing of extraction curves and other related information can be done through posters, files, and other means, making coffee data sharing more convenient.

BOOKOO EM assists you in exploring the art of coffee extraction and improving coffee quality.

Disclaimer: This pressure sensor is a high-precision measuring device. Please adhere to the instructions outlined in this manual without deviation. This product’s warranty does not cover damage caused by improper use.

Basic Information

• The continuous working time is the continuous Bluetooth connection time, the above number

1. Installation

• Compatibility
  • Compatible Devices (Direct Fit): Coffee machines with G1/8 thread such as Flair58, Cafelat Robot, La Marzocco GS3, ALM KOPi (all models), and other coffee equipment with G1/8 thread
  • Compatible Devices (Requires the M6 Adapter): E61 group head espresso machines and coffee machines with M6 thread and such as Lelit v3, Rocket R58, Profitec Pro 400, 500, 600, 700, ECM Puristika, Mechanika, Synchronika
  • Others: Devices with a pressure gauge can generally be used. It is recommended to seek professional guidance for any modification or retrofitting, ensuring proper sealing at the interface. The BOOKOO team is not responsible for any modification actions.
• Installation Steps
  • Use a wrench to remove the original pressure gauge, exposing the threaded port.
  • For devices with G1/8 thread, directly screw the EM pressure sensor onto the port. For devices with M6 thread, connect the provided adapter before screwing on the EM pressure sensor.

• Notes
  • When connecting to a group head operating at 100°C, it is necessary to reduce heat transfer by using an adapter to ensure the EM operates within the normal working temperature.
