Product Details
Product Overview
The HM Instruments HM-RF2 milk analyzer is designed for routine multi-parameter analysis of liquid dairy products. Ultrasonic sensing supports measurement of milk composition, while pH and conductivity extend the instrument to an 11-parameter configuration.
For dairy farms, fresh milk collection stations and small to medium-sized dairies, it provides a compact way to review composition and milk quality indicators.
Key Features
- Android operating system and a 7-inch touchscreen for setting tests and viewing results.
- Ultrasonic sensing with automatic correction for temperature and acidity influences.
- Compact construction with a simplified internal fluid path and peristaltic pump.
- Low sample demand, good measurement repeatability and low power consumption.
- Built-in automatic cleaning function to support routine maintenance.
- Integrated thermal printer with editable test reports.
- Wi-Fi connectivity for transferring results to a platform or PC.
- Data management platform for storing uploaded results and analysing trends.
Applications
Suitable sample types include cow milk, sheep or goat milk, UHT milk and camel milk. Use the calibration and sample preparation procedure for the milk type being tested.
Testing items include fat, protein, lactose, solids-not-fat, density, added water, freezing point, ash, milk temperature, pH and conductivity.

Related Models
HM-RF1 provides nine parameters, without pH or conductivity. HM-RF2 provides 11 parameters. HM-RF3 is the 11-parameter dual-pump configuration. Select the model according to the required measurements and pump configuration.
Operation and Support
Routine milk analysis does not require chemical test reagents. Cleaning agents and calibration solutions are still required for maintenance and calibration; acidic and alkaline cleaning agents are included in the standard configuration. Follow the instruction manual for sampling, calibration and cleaning.
