Product Introduction

The HM-DS Handheld Liquid Density Meter from HM Instruments is a portable U-tube oscillation densitometer designed for fast and accurate density determination of liquid samples. The instrument measures sample resonance frequency through an oscillating U-shaped tube, delivering density readings between 0.0000 and 3.0000 g/cm³ with a resolution of 0.0001 g/cm³.

Built-in concentration calculations cover alcohol content, sugar content, sulfuric acid concentration and Plato concentration, while users can also create custom concentration formulas. Equipped with a 2.4-inch full-color LCD, ergonomic single-hand grip, NFC tag reader, barcode scanner and built-in suction pump, the HM-DS is suitable for chemical manufacturing, food and beverage QC, petroleum analysis and laboratory applications.

Applications

Chemical industry — density measurement of various chemical substances for product quality and process stability
Food & beverage industry — density of fruit juices, beverages and alcoholic drinks for QC and process control
Petroleum industry — density of crude oil and finished oil for product quality assurance
Pharmaceutical, environmental protection and educational density measurement
