Draminski COFFEE & COCOA Twist Grain Pro Moisture Meter


Why choose DRAMIŃSKI TG pro coffee & cocoa?

Ambient factors such as humidity, excess air, light and temperature signigicantly affect flavour, aroma and shelf life of coffee and cocoa.

Coffee samples contain aromatic oils which are neutralised by exposure to insufficient or excessive temperature. In addition, a temperature change from very low to positive exposes the material to negative moisture effect (condensation effect).

This results in neutralization or reduction of flavourings contained in the coffee, thus reducing its quality.

The DRAMIŃSKI coffee and cocoa moisture tester precisely and quickly evaluates the condition of a tested material. This will ensure adequate security of stocks and avoid financial losses.

DRAMIŃSKI TG pro coffee & cocoa moisture tester guarantees the highest product quality. Coffee and cocoa importers and exporters, coffee roasting plants, coffee shops, cafés and baristas will appreciate the moisture tester in their daily work. Especially during production, processing, storage and transport.

The device is used at every stage of coffee and cocoa production, such as:

  • during the parchment coffee drying process
  • during the green coffee drying and storage
  • during roasting and storage of ground coffee

Available species and measuring ranges:

  • Cocoa 4% – 20%

Warranty: 3 Years

You will quickly appreciate advantages of this moisture meter which is ideal to be used in the field because:





As the manufacturer, we offer our moisture meter with a 3-year warranty. Before sending to the client, each device is checked for quality of the manufacturing process and correct measurements.

Our Service Unit will do their best to repair and check your device as soon as possible from the delivery date. In cases with a more complex repair process, whenever possible. Our company is certified with two rigorous Quality Management Systems: ISO 9001 and ISO 13485, which proves our professionalism and the highest quality of our products.



The moisture meter has two operational modes that are tailored to the needs of a user and can be easily changed on the menu:

Basic – for a quick and accurate moisture measurement (intuitive and very convenient handling, even for non-experienced users).

Advanced – activates many additional functionalities that will be appreciated even by the most demanding clients. This mode allows for recoding the moisture and temperature measurements with date and hours, data transfer to the PC, temperature measurements with an external temperature probe and many other options.



Four frequencies ensure that the measurement is steadier and its result is less susceptible to unusual samples, the risk of blips is lower and the repeatability is high. You can quickly measure the moisture of grain with an accuracy of ±0.5% for normalized grain.

Grain temperature is also an important factor for moisture measurements and TwistGrain pro is thus equipped with a digital temperature sensor (built in the measuring chamber) to ensure a very accurate measurement (accuracy: ±0.5°C). TwistGrain pro has an automatic temperature compensation mode.

Importantly, DRAMINSKI S.A. devices do not require periodical calibration service checks.



You can fill the measuring chamber without any additional tools or special medium. Simply, grasp some grain with the device, push away any excess towards the edge of the chamber and tighten the cap.

When screwing the cap, the acoustic signal will indicate that the grain sample is adequately squeezed. Since keeping the device comfortably in your hands (tightening the cap does not require using much force) it is not tiring even after many measurements.



A large graphic and LED- illuminated display allows reading the result in any conditions (field/warehouse, full sun/night). The menu enables the user to adjust the display settings: illumination time, illumination intensity and contrast.



The TwistGrain pro device is equipped with the real time clock, which, together with huge data storage capacity, allows recording 50,000 moisture measurements and temperature measurements from the external probe (records with date and hour).

The data storage mode covers up to 400 species and 20 language versions and makes the device a very useful and universal tool for each farmer, expert, drying room operator, gardener, barista or entrepreneur for the food and agriculture industry.



The TwistGrain Pro moisture meter comes with free, multi-language software for data transfer to PCs.

The software generates Excel sheets and measurement reports (by species and by measurement date), presents the moisture changes in time on the graphs, filters the results by date, allows browsing the stored data, has archiving functionality limited only by the hard disc capacity, saves the documents as PDFs, prints, and has many other useful functions.



The regular model of TG pro moisture meter has a list with 30 grain species (as detailed below). However, if required by the client, we can load more species before delivering the device. If the list does not feature a species you are looking for, please Contact Us. TwistGrain Pro will accommodate up to 400 species.

All available calibrations can be found in the “Available species” bookmark.

The TG Pro display allows you to conveniently read the full name of a given species without any abbreviations or symbols (the long name scrolls automatically on the display).



Do you want to check the moisture of a species that is not put on your device? This is not an issue with the TG Pro moisture meter.

All you need to do is to select the option “Add species” and then enter a specific code that permanently activates the required calibration of the list.

Thanks to such innovative solutions, a user can, in just a couple of minutes and without going out or sending the device to the service section, add a new species to the list of available measurement options or deactivate the species they want to delete (to get the code, please Contact Us).



Additionally, you can order the external temperature probe that generates precise measurements (±0.5°C) of crops stored in piles, flat warehouses or silos.

The device can work with any number of probes with varied construction and length (and there is no need to calibrate the probe for the device). Each probe wired up to the moisture meter can be assigned a name according to personal preferences (the data storage capacity allows recording the names of max. 20 probes).

When the name is recorded for a given probe, a catalogue is created in the data storage; this catalogue will accommodate measurement to transfer them to the PC for analysing, generating reports, archiving etc. When the probe is wired up, the device automatically detects it and displays the name.

High-quality stainless-steel guarantees durability (and corrosion resistance). The data storage capacity allows recording 50,000 temperature measurements with date and hour.



A quick check of moisture and temperature will help you manage, store or sell crops more efficiently, which will quickly translate into increased profits for your business.



The TG Pro comes with a durable mini-USB port that is used to connect an external temperature probe and transfer the data to the PC, automatic updates and moisture curves. That’s why the DRAMINSKI TwistGrain Pro is simply unmatched!!!



Twist Grain Pro has 4 buttons on the keyboard for comfortable and easy operation (the OK button is to confirm, the ESC button to cancel, and the arrow keys ↑↓ help with intuitive navigation).

To ensure full satisfaction, TG pro has many options that are accessed from the menu, such as:

  • the option to choose the number of measurements that are used to calculate average moisture,
  • the option to record the results of single measurements or calculated mean,
  • possibility to make modifications of readings separately for each species (the outcome of modification is seen while measurements are being taken),
  • the option to add new species remotely with special codes,
  • full regulation of display settings,
  • possibility to set the automatic switch-off time,
  • management of external temperature probes (adding, editing, deleting),
  • management of data storage (free space checks, formatting, date and time setting),
  • the option to choose the language interface
  • the option to change the temperature range,
  • and many other useful functionalities with unrestricted access.


The robust casing, made of shock-resistant ABS, metal elements and purpose-braced, non-cracking cap guarantee extreme durability.
