Features of this group head thermometer model are:
1x AAA battery power supply. 
Battery case has also the function of support for the display.
Detachable sensor's cable

General description:
The thermometer measure the temperature of the group head of all La Pavoni lever espresso coffee machines (Europiccola, Professional).
Very useful also for others coffee machines: Elektra Microcasa, Faemina, Microcimbali, commercial E61 group, Rancilio Silvia, Caravel, La Peppina etc...

It has a small flat sensor (ideal to measure metal surfaces, with pre attached aluminum & Kapton tape for fast installation) and a very thin cable.

Included:
Some cm of spare part tape: Tesa aluminum adhesive tape (professional high temperature resistant 160°C) and high quality 3M Kapton (orange) tape (high temperature resistant 250°C).
Suitable for about 4 additional applications.

Installation note:
Remember to fix the cable on the back/bottom part of the boiler (behind the water level glass) with 1 cm of Katpon, so that a random movement of the cable or thermometer does not propagate to the sensor junction. 

Specifications of the thermometer: 
Power supply: 1x AAA battery
Accuracy of 0.1°C
1 sec refresh time.
Sensor wire length about 34 cm  (note: length can be customized for different mount, send me a message) 
Max temperature reading: 110°C

The importance to measure the group temperature:
Espresso taste is very sensitive to extraction water temperature. You can feel the taste difference even with a 1° degree variation. 
Without a thermometer, it's like to be blind about the actual temperature, leading to a frustrating lack of control of taste consistency.
Typical temperature range is between 88°C to 96°C (190°F to 205°F). It depends very much to the roasting level and type of the coffee.
The group head temperature in the Pavoni is like a reference point: it should be some degrees lower than the desired extraction water temperature.
The important point is that if the temperature of the group is the same, also the extraction temperature will be the same.
For direct measure of the actual water extraction temperature inside the portafilter i sell also another type of thermometer (called portafilter thermometer) with a 5cm long flat sensor.

Installation instructions:


The sensor comes with pre attached tape. However for future replacements, i suggest to attach the sensor with Kapton first and then on top of that 1,5 x 2,5 cm of aluminum tape.

Clean the metal surface before application. Use alcool or acetone (much stronger) for any cleaning on chrome, it works really well also on removing aluminum tape glue residues.

Attach the sensor with kapton and thoroughly apply pressure on the tape around the black tiny spot (that's the actual delicate sensor, don't press it)
Then finish on top using 1,5 x 2,5 cm of aluminum tape.
Aluminum tape is always necessary because it is thermally conductive and it blends well with the chrome surface.

Italian translation:
Vendo un termometro digitale con piccolo e sottile sensore ideale realizzato specificamente per la misurazione della temperatura del gruppo di tutti i modelli di macchine per caffè espresso La Pavoni (Europiccola, Professional) e adatto anche ad altre macchine da caffè a leva.

l sensore piatto è ideale per la misura di superfici metalliche.


Il sensore si applica con speciali nastri resistenti ad alta temperatura. Verranno spediti alcuni centimetri insieme al termometro.
Sotto trovate due link video che ne mostrano l'installazione ed utilizzo.
Il sensore è montato alla superficie del gruppo tramite dei nastri resistenti ad alte temperature in alluminio e Kapton che verranno inviati insieme al termometro (alcuni cm):
Montaggio iniziale con 1x2 cm di Kapton (lo invio già applicato al sensore per semplificare la prima installazione) e sopra un altro strato di 1,5x2,5 cm di nastro in alluminio. Infine un film addesivo cromato.

International SHIPPING options:
  1. "Postapriority internazionale" has not updated tracking. The provided code will only show that it's "in working state" (italian translation of "in stato di lavorazione"). This is the link: https://www.poste.it/cerca/index.html
  2. "Posta Raccomandata Internazionale" is a registered mail. Tracking is available for most countries of the World. Full list of countries is provided below (**)
Both shipping methods use the Italian postal service (www.poste.it) and they will be delivered by the national postal service of the country of destination.
Delivery time for both methods is the same (note that eBay estimates are not correct and too optimistic).
On average it will take about 2-3 weeks for Europe/UK/Canada/US and may take a couple of weeks more for the rest of the World. Precise delivery time is unpredictable, it depends on the country of destination.

In case of delivery problems (address etc..), you may contact your nearest postal office for information about the
the mail. If it can't be delivered, it will be automatically returned to the sender after some time.
