DF Ecomatik Fruit & Vegetable Dendrometers (S-XL Fruits)
Fruit and Vegetable Dendrometers are special dendrometers for measurements on circular fruiting bodies. The special design allows that the fruit is firmly fixed in measuring frame, without affecting its growth. Flexibly fixed on the branch, the frame sustains the weight of the fruit and relives the peduncle. The DF series comprises three different models.
The DF1 for small or slow growing fruits (e.g.cherry, grape), the DF2 for medium sized and fast growing fruits (e.g. apple, orange) and the DF3 for large and fast growing fruits (e.g.pumpkin).

| Use area | small or slow growing fruits | medium or fast growing fruits | large or fast growing fruits |
| Suitable for fruit diameter | 0-11 cm (larger or smaller frame sizes on request) | ||
| Range of the senor | 15 mm | 25.4mm | 50.8mm |
| Resolution | The resolution of the sensor itself is infinite. The resolution of readings is determined by connected data logger, e.g. | ||
| CR1000:2 µm Logger DL18: 0.3 µm |
CR1000: 3.3 µm Logger DL18: 0.5 µm |
CR1000: 6.6 µm Logger DL18: 1.0 µm |
|
| Accuracy – Dendrometer Dependent: |
Max.3.3% of reading (stable offset) |
Max. 1.97% of reading (stable offset) |
Max. 0.98% of reading (stable offset) |
| Accuracy – Data Logger Dependent, |
e.g.: CR1000:± (0.04% of reading+6µm) Logger DL18:0.1% |
e.g.: CR1000:± (0.04% of reading+10µm) Logger DL18:0.1% |
e.g.: CR1000:± (0.04% of reading+20µm) Logger DL18:0.1% |
| Temperature coefficient | < 0.2 µm / C in the whole range | ||
| Linearity | <2% | < 0.7% | < 0.5% |
