Eureka Digital Scale Precisa Digitalwaage (mit Bluetooth)
Eureka Digital Scale Precisa - precision for the perfect coffee extraction
With the Eureka Digital Scale Precisa you can measure your coffee extraction with millimeter precision. The scale impresses with its bright LCD display, two intuitive TOUCH fields and a rechargeable battery via micro USB. It is the ideal tool for anyone who places the highest value on precision and quality.
The Bluetooth version of the Eureka Precisa combines precise weighing with a digital workflow. A wireless connection allows you to pair the scale with a compatible app, document every purchase in real time and repeat successful recipes without guesswork. The result: more consistency in the cup, fewer steps, more control.
Why the Bluetooth version?
- Live tracking of weight and time: brewing and pour-over sessions are logged in the app - including time stamps and weight curves.
- Save and reproduce recipes: Store target values (e.g. dose, yield, brew ratio, target time), save them as a profile and call them up again at any time.
- Automatic modes with app support: espresso or filter mode with auto-timer/auto-tare - fewer manual steps, fewer sources of error.
- Evaluation & consistency: Shot history, comparison of good vs. fluctuating draws and export of data for quality control.
- Guided work: Step-by-step workflows for beginners, fine parameterization for advanced users.
- Over-the-air updates: functional improvements and fine-tuning via firmware/app updates - without new hardware.
- Team and device sharing: share recipes, synchronize sessions - ideal for multi-person households or small bars.
Advantages in everyday life
- Reach your goal faster: Auto-Tare and Auto-Timer reduce manual work on the portafilter or dripper.
- Fewer fluctuations: Consistent target values thanks to saved recipes and clear target displays in the app.
- Better troubleshooting: Recognize deviations in time, yield or ratio immediately and take targeted countermeasures.

Frequently asked questions
-
Can I use the scale without the app?
Yes, all basic functions of the scale can be used stand-alone; Bluetooth supplemented by logging, recipes and updates. -
Does the app save my recipes?
Yes, you can store target values, save sessions and reproduce them identically later. -
Does the Bluetooth version also work on multiple devices?
Yes, you can pair the scale with different smartphones/tablets one after the other; one device is usually active at the same time. -
Are firmware updates available?
If provided by the manufacturer, updates can be easily installed via the app.
Conclusion: The Eureka Precisa with Bluetooth is the right choice if you want to measure, document and reproduce your espresso and filter workflow. More control, less scattering, better results - cup after cup.

Frequently Asked Questions
I bought a new coffee grinder from Naturbohne and there are coffee residues in it.
Please note: Some manufacturers test their coffee grinders before shipping, which means that small coffee residues or bean residues can occasionally be found in the grinder. This procedure is used to test functionality and is considered a quality feature. Of course, we only sell new products - unless expressly stated otherwise.
Static charge – coffee grounds spray out from the side
With some coffee grinders, the ground coffee can become statically charged and spray out of the portafilter at the side. This means that not all of the ground coffee gets into the portafilter, which can lead to uneven extraction. Our recommendation: Use a dosing funnel to ensure that all of the ground coffee is precisely fed into the portafilter - for optimal espresso enjoyment.
What is dead space in coffee grinders?
Conventional coffee grinders often leave a so-called dead space in which coffee residues accumulate. These residues can not only affect the freshness, but also lead to old and fresh coffee grounds being mixed, which negatively affects the taste. In contrast, single dose grinders have a well-thought-out design that eliminates the dead space. Each portion is ground individually and precisely so that no residues are left behind - for a consistently pure and full-bodied coffee experience.
Which portafilter fits my espresso machine?
When choosing the right portafilter for your portafilter machine, it is important to know that each manufacturer develops its own brewing group - the most well-known is the Faema E61. However, this does not mean that any portafilter will fit without any problems. An incompatible portafilter can leak, which will have a direct negative impact on the quality of your espresso. We therefore recommend using either the portafilter originally supplied or one that is explicitly stated to be compatible with your machine. This will ensure that the pressure is optimally built up and the espresso is perfectly extracted.
Can I visit you or pick up the goods personally?
Yes, of course, you are welcome to come by and look at our products by appointment. We would be happy to advise you personally. The best thing to do is to send us an email with a few suggested appointment times.
We are located 5 minutes from the motorway between Stuttgart and Lake Constance on the edge of the Black Forest.
Important note, first use coffee grinders
Another little tip for the perfect start with your new mill:
You will get the best grinding result after you have ground about 1-2 kg of beans. It is best to use a few cheap beans so that the grinder can work optimally. And if you are wondering what you can do with the bean flour - it is perfect plant fertilizer! 🌿
It contains nitrogen, potassium, sulfur and phosphorus and is a real nutrient bomb for your plants.
Könnt ihr bei meiner Siebträgermaschine eine Offset Kalibrierung durchführen ?
Es gibt einige Argumente, die gegen eine Offset-Kalibrierung bei Lelit-Siebträgermaschinen sprechen, insbesondere bei Modellen wie der Lelit Bianca. Diese beziehen sich vor allem auf die Komplexität und die Limitierungen des Offsets als alleinige Lösung für Temperaturprobleme:
- Temperaturschwankungen und Instabilität. Der Offset berücksichtigt eine konstante Differenz zwischen Kesseltemperatur und Brühtemperatur. In der Praxis können jedoch Temperaturschwankungen auftreten, z. B. durch längere Standzeiten oder kontinuierliches Brühen. Dadurch ist die tatsächliche Brühtemperatur nicht immer präzise vorhersehbar.
- Abhängigkeit von Umgebungsbedingungen. Faktoren wie Raumtemperatur, Luftfeuchtigkeit und der Zustand der Maschine (z. B. Aufheizzeit) beeinflussen die Brühtemperatur erheblich. Ein fester Offset kann diese Variablen nicht dynamisch ausgleichen, was zu ungenauen Ergebnissen führen kann.
- Wärmeverlust bei Standzeiten. Nach längeren Pausen kühlt die Brühgruppe ab, und die Maschine benötigt Zeit, um wieder auf die gewünschte Temperatur zu kommen. Ein korrekt eingestellter Offset kann dies nicht kompensieren, weshalb zusätzliche Maßnahmen wie ein “Cooling Flush” nötig sind.
- Fehlkalibrierungen ab Werk. Bei einigen Lelit-Modellen wurde festgestellt, dass der Offset ab Werk oft ungenau eingestellt ist (z. B. 4–8 Grad zu niedrig bei der Lelit Bianca). Dies erfordert eine manuelle Nachkalibrierung durch Fachpersonal, was für Endnutzer kompliziert sein kann.
- Missverständnisse in der Anwendung. Viele Nutzer sind durch widersprüchliche Informationen zur Offset-Einstellung verunsichert, was zu Fehlanpassungen führen kann. Beispielsweise wird oft erwartet, dass der Offset allein alle Temperaturprobleme löst, obwohl er nur ein Teil eines komplexeren Systems ist.
Fazit
Die Offset-Kalibrierung ist ein nützliches Werkzeug, aber sie sollte nicht isoliert betrachtet werden. Eine Kombination aus präziser PID-Steuerung, regelmäßiger Wartung und angepassten Techniken (z. B. Spülshots) ist notwendig, um optimale Brühergebnisse zu erzielen.
