Milk Hydrometer Lactometer 15-40 Glass with Protective Case

Milk Hydrometer Lactometer 15–40 — Color-Coded Pass/Fail, Protective Case Included

Quickly verify milk purity and detect adulteration with this professional glass lactometer. The color-coded green/red reference bands give you an instant visual pass/fail result — no calculation needed. Comes with a protective plastic case to prevent breakage during transport or field use.

What Does the 15–40 Scale Mean?

The scale measures milk density in Quevenne degrees (°Q), which corresponds to the specific gravity of milk:

• Pure whole milk typically reads between 28–33°Q (green zone = pass)
• Readings below 28°Q (red zone) suggest the milk has been diluted with water
• Readings above 33°Q may indicate skimmed or partially skimmed milk
• The 15–40 range covers all common milk types including whole, semi-skimmed, and skimmed

Typical Use Cases

• Dairy farms: Spot-check raw milk quality at collection to detect dilution or adulteration before processing.
• Milk collection centers: Fast screening of incoming milk batches — result in under 30 seconds.
• Food processing facilities: Quality control verification before milk enters production.
• Laboratory analysis: Routine density measurement as part of a broader milk composition test.
• Home cheesemaking & dairy hobbyists: Verify milk quality before culturing or fermenting.

How to Read the Lactometer

1. Bring the milk sample to 15–25°C (59–77°F) for accurate results — temperature affects density.
2. Pour the milk into a tall cylinder (at least 250 ml) so the lactometer floats freely.
3. Gently lower the lactometer and allow it to settle without touching the sides.
4. Read the scale at the bottom of the meniscus (curved milk surface) at eye level.
5. Compare your reading to the color bands: green = acceptable, red = investigate further.

Note: For best accuracy, test milk at the same temperature each time. Cream separation or very cold milk can affect readings.
