Density Meter | Digital Hydrometer

The portable density meter is ideal for beginners. It measures sample density directly and easily on-site. Using the built-in pump, the device draws samples from the storage container and instantly displays the results—either as density or as concentration in units like °Brix, %v/v alcohol, or %w/w H₂SO₄ (sulfuric acid). Thanks to its lightweight and compact design, the measuring device is also suitable for hard-to-reach samples, such as batteries in tight shelves or wine samples from stacked barrels.

Technical Highlights of the Density Meter Compared to the Glass Hydrometer
  • Minimal Sample Volume: Only 2 ml of sample is needed, helping to avoid sample waste.
  • Direct Sample Collection On-Site: The built-in pump draws samples directly from the container, simplifying the process.
  • Integrated Conversion Table: Results are displayed directly in preferred units, eliminating the need for extra calculations.
  • Wide Measurement Range: This device can replace a full set of hydrometers.
  • Automatic Temperature Compensation: Results are precise and reliable within seconds.
  • Efficient Data Management and Easy Transfer: Stored results can be automatically transferred, eliminating manual note-taking.
  • Consistent Results: The results are reliable and consistent, regardless of user experience.
  • Lightweight and Robust Design: This allows for easy transport and safe storage.

This device is the lightest of its kind on the market. Its slim design allows it to fit into narrow spaces, such as wine cellars or battery production facilities. A protective case, rubber housing, and shoulder strap make the device ideal for safe on-site use. It is leakproof (IP54) and reliably resists sample splashes. The chemical resistance of sample-contacting parts has been thoroughly tested, protecting the device from the effects of solutions and acids for a long-lasting lifespan.

Smart Features for an Optimized Workflow

The device includes a backlit display and an illuminated measuring cell, making it easy to use even in dark environments. Sample IDs can be saved and assigned to sampling locations. Stored results can be conveniently printed or exported via the IrDA interface, enabling quick and efficient data processing.

Force Tensiometer | Interfacial Tension

Versatile Functions for Precise Tension Measurements

The Force Tensiometer provides a modern and reliable method for the precise determination of surface wetting. By measuring the tensile force generated when immersing a ring or plate, the device delivers accurate results. Two well-established methods are available for determining surface and interfacial tension between two media: the Du-Noüy ring method and the Wilhelmy plate method.

The digitally controlled Sigma 200 Tensiometer performs these measurements fully automatically. With a single button press, the process starts, ensuring a fast and straightforward operation. This user-friendly design not only saves time but also ensures precise and reproducible results. In addition to tension measurements, the Tensiometer allows for the measurement of liquid density, further enhancing its versatility.

Comfortable Data Collection and Precise Quality Analysis

The Tensiometer operates as a standalone device, equipped with a motorized table that enables highly precise positioning of the sample vessel. During measurement, the Du-Noüy ring immerses in the sample, and the device captures the forces generated. The motorized sample table gradually moves downward, measuring the forces directly on the ring or plate lamella. The integrated display immediately shows the measurement values, enabling quick, straightforward data interpretation.

One particularly valuable feature of the digital Tensiometer is its capability to analyze the interfacial tension between oil and water. The ring method provides early indications of the oil aging process, which plays a key role in quality monitoring. ASTM Standard D971-99 2012 describes and standardizes this method for interfacial tension measurement. This makes the digital Tensiometer an essential instrument for quality control in numerous industries. In the chemical and food industries, it meets the highest standards of accuracy, speed, and efficiency, ensuring continuous quality assurance.
