Used For: Precise and portable moisture and temperature measurement of grains
The Draminski Twist Grain Pro provides fast, easy and precise moisture and temperature measurement. The small, ergonomic design fits perfectly in your hand for testing anywhere. The robust casing, made of shock-resistant ABS, metal elements and purpose-braced, non-cracking cap guarantee extreme durability.
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.
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).
High-quality stainless-steel guarantees durability (and corrosion resistance). The data storage capacity allows recording 50,000 temperature measurements with date and hour.
The regular model of TG pro moisture meter has a list with 30 grain species. 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 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.
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 devices do not require periodical calibration service checks.
