KERN Digital Refractometer - ORM 2CO (Coffee) - Refractive index, Brix, Coffee TDS 2
KERN ORM 2CO
The ORM 2CO is a digital handheld refractometer made for measuring dissolved solids in coffee. It helps baristas, roasting houses, and coffee producers check the strength and quality of brewed coffee. The device shows the TDS (Total Dissolved Solids) value, which indicates how much coffee material is extracted into the drink.
This refractometer uses the total reflection measuring method, which gives accurate and stable results. It is ideal for testing brewed coffee or espresso and comparing different extraction levels. The ORM 2CO can also display results in Brix or refractive index, giving you multiple options for analysis. For coffee roasting plants, the TDS value helps control the solubility of beans and evaluate the roasting process.
The large digital display is easy to read and also shows the current temperature of the sample. The automatic temperature compensation (ATC) keeps the result accurate even when the liquid is not at room temperature. You do not need to make manual corrections, which saves time and ensures precision.
Calibration is quick and simple using distilled water. The housing is strong and durable, made for regular daily use. The device is protected against dust and water according to IP65 standards, so it can be rinsed under running water after testing.
The ORM 2CO is light, compact, and comfortable to hold. It runs on one AAA battery and can take mean value measurements for even more stable readings.
The package includes a prism cover, pipette, storage box, AAA battery, and user manual.
