How to install this Coffee Sensor. 

Coffee Sensor - E61 HX and Dual Boiler Digital Grouphead Thermometer

Coffee Sensor offers valuable and instant information during the entire brewing process of your coffee.

Firstly, Coffee Sensor tells you if your machine is ready to go before your first coffee of the day, by indicating E61 grouphead idle temperature. After this, you will know how to correctly adjust the cooling flush (for HX coffee machines), by knowing the perfect moment of finish and start of the coffee extraction. During brewing, it will show you the exact temperature level throughout the entire extraction to enable optimum results from your coffee.

Easily attached to any E61 grouphead by removing small hex screw and screwing in the Coffee Sensor. The Coffee Sensor comes with extra copper packing washers, hex screw removal allen key, small spanner to tighten the Coffee Sensor and installation instructions.

Coffee Sensor offers you the new 2020 model of the universal adapter and thermometer.

The 2020 model, compared to the 2019, comes with new All Black mask (face) and soon, we will introduce after a few more tests, readings calibration possibility.


The sensor is compatible with any HX and SBDU E61 group head, with a M6 thread inside.

Coffee Sensor offers a lifetime warranty for all metal parts manufactured by Coffee Sensor

This includes of course the Universal Adapter made from Stainless Steel.

The thermometer is covered by full 1 year warranty.

Coffee Sensor cannot offer warranty for the consumables such gaskets, copper washers, battery.

Comprised of a stainless steel adapter and digital thermometer, Coffee Sensor Thermometer provides instant feedback to the user. The two main benefits are:

1. Knowing the group head idle temperature;

2. Knowing the water temperature right near the brew point/coffee puck.

Thus providing repeatable, empirical information to help take the guesswork out of the process.


The installation of the Coffee Sensor Thermometer doesn’t need special tools, conditions or high tech knowledge. Therefore, you just have to make sure the E61 coffee machine is turned off and cooled down. Remove the Allen head located just on front of the group head and replace it with our product. No need for Teflon tape, sealant, cutting or any sort of adaptations. Everything you need to install our product is located in the retail box. The most important condition is to make sure that your coffee machine model has an E61 exposed group head.

Please understand that the Coffee Sensor Thermometer is located just near the coffee puck, at a maximum of 1.25″ above. So the readings the sensor gives you are a little bit different comparing to the actual temperature of the water that hits the puck. Feel free to add a maximum 2 degrees Celsius above the readings to calculate a more realistic extraction temperature.
Depending of the construction type of your coffee machine, the readings can vary between different espresso machine manufacturers. Usually the difference is into the angle of witch the sensor is inserted into the group head.

The thermometer has both Celsius and Fahrenheit readings. Switch freely using the button from the thermometer.

Features and benefits

2. Digital thermometer with Celsius / Fahrenheit switch button. Working temperature of the thermometer: between -50 and 200 degrees;

3. Two copper sealing washers offered into the box (one spare), that are highly resistant to friction and high temperature for longer periods of time than classical rubber or Teflon washers;

4. One battery;

5. Full installation kit and written instructions in the box. The installation kit consists of one Allen key, one fix 10 mm key and two copper sealing washers (one spare).
