MILKOTESTER MASTER ECO 2 is a compact ultrasonic milk analyzer for farms, small dairies, milk collection centers, cheese producers, and quality-control work. It measures milk composition on-site without chemical reagents. The supplier describes results in approximately 40 seconds using a 20 mL sample.
Check key measurements including fat, protein, lactose, solids-not-fat (SNF), density, salts, added water, freezing point, and sample temperature. The analyzer is manufactured in Bulgaria, EU, and is designed for bench-top or field use with compatible AC power or a 12V DC supply.

Milk Types & Calibrations
Factory presets: cow milk, sheep milk, and UHT milk. Other available calibrations may include goat, buffalo, pasteurized, mixed (50% cow / 50% buffalo), skimmed milk, and whey. Please tell us the milk type before ordering if you need a different setup; supplier-approved alternative calibrations can be arranged upon request, subject to confirmation.
How to Use
- Thoroughly mix and filter a representative milk sample.
- Ensure the sample is within the required temperature range of 5–35°C.
- Select the appropriate milk calibration, place the sample under the inlet, and start analysis.
- Read the results from the display and save or transfer them as needed.
For accurate readings, follow the manufacturer’s sample-preparation, cleaning, and calibration instructions. The supplier's current product page specifies a 20 mL sample, approximately 40 seconds per analysis, and up to 90 samples/hour. The linked manufacturer manual instead specifies a 25 mL sample and 50 samples/hour including cleaning. Please confirm which specifications apply to the supplied production revision.
Optional Add-ons
-
pH measurement and pH probe: optional acidity testing for milk-quality and fermentation workflows.
-
Conductivity measurement: optional electrical conductivity readings.
-
Bluetooth: optional wireless data transfer to supported devices.
-
External printer: RS-232 connectivity can be used with a compatible thermal printer.
