Product Details
HM-RF1 measures nine milk-quality parameters. HM-RF2 and HM-RF3 add pH and conductivity measurement; HM-RF3 also provides a dual-pump configuration.
Product Overview
The HM Instruments HM-RF1 is a 9-parameter milk analyzer for routine composition and physical-property testing of liquid dairy products. It measures fat, protein, lactose, solids-not-fat, density, added water, freezing point, ash and milk temperature. An ultrasonic sensor, Android touchscreen and integrated printer combine sample measurement, result review and report output in a compact instrument.
It is intended for dairy farms, fresh milk collection stations and small to medium-sized dairy businesses. Documented sample types include cow milk, sheep milk, UHT milk and camel milk. Select the appropriate sample calibration and follow the supplied instructions for the milk type being tested.
Key Features
- Ultrasonic sensor with automatic correction for acidity and temperature influences.
- Android operating system and a 7-inch touchscreen for setup and result review.
- Simplified internal tubing and a peristaltic pump for sample handling.
- Low sample demand and low power consumption.
- Built-in automatic cleaning function for routine instrument care.
- Integrated thermal printer with editable inspection reports.
- Wi-Fi connection for transferring results to a platform or PC.
- Data management platform for storing uploaded records and reviewing trends.
