Description:
This is the latest version of the famous Coffee sensor digital thermometer for E61 coffee groups. It is now all black, has a shorter tip for even more accurate reading, and now fits Vibiemme.
The sensor shows idle group temperature and extraction temperature.

It is ideal for retrofitting your coffee machine so you can monitor the temperature of the coffee groups.
A big issue with coffee is the temperature at which the coffee is extracted. Knowing the temperature of the group when brewing will help prevent burning speciality coffees.

The ideal temperature is 88ºC - 94ºC.
Some coffees burn at 90ºC - like 100% arabica speciality types.
Espresso blends are more robust and can go as far as 94ºC

💡The Coffee Sensor Thermometer is located close to the coffee puck, so the readings the sensor gives you are a little bit different compared to the actual temperature of the water that hits the puck. Add +2 degrees Celsius to the readings to calculate a more accurate extraction temperature. The readings can vary between different espresso machine manufacturers, due to the angle of the sensor in the group head.

Senor for Mara X
I had another temp sensor got on line from china LED light and only read in celsius had nice large numbers but seems like it was always turning off, and battery life was short live. Watch youtube on coffee sensor and had very favorable reviews, the numbers are smaller then my other sensor but are backlit and for me easyer to see and unit stays on longer and has both Celsius and Fahrenheit and what was crazy is I got it and had it sent to U.S. cheaper than I could find it in the U.S. so far very happy and recommend it for anyone wanting temp sensor for E61 :)

Coffee Sensor E61 Digital Thermometer

Will this thermometer fit the Rocket Mozzafiato? It's a different machine to the Appartamento, but may use a similar E61 group head. Thanks!
Andrew from United Kingdom
Hi Andrew, I think it fits all Rocket E61 groups, inc Mozzafiato. To be sure remove the group screw and measure the depth - If your e61 chamber is shorter than 16mm, the probe would be too long and would block the coffee.

Hi, I see many of these same temp meters on aliexpress for a fraction of cost. What differentiates these? Any authenticity or just markup on your side?
Marco from United Kingdom
Hi Marco, Coffee Sensor in Romania designed and manufactured the E61 digital thermometer many years ago and has many imitators but few equals. They are well-engineered, tested and proven to work. I cannot speak for Aliexpress, but we have been selling these E61 digital thermometers for many years without any issues.
