Labbox hydrometer, for general use, Tp. 20 ºC
The compact hydrometer from METRIA is ideal for professionals who want to carry out reliable density measurements in laboratories, production facilities or training facilities. It has been specially developed for determining the specific gravity of all types of liquids and delivers precise measurement results at a calibration temperature of 20 °C. Compared to similar measuring instruments, this model impresses with its robustness and ease of use without sacrificing accuracy.
Reliable density measurement for versatile applications
This density meter is not certified to a specific standard and does not require an additional calibration certificate. Nevertheless, it scores with its high-quality design, which ensures reliable results. For a correct reading, the device should be viewed below the meniscus, which minimizes measurement errors. Thanks to its compact design and solid workmanship, the hydrometer is also suitable for frequent use under different conditions.
The fact that it is designed for the unit g/ml and therefore enables clear conversion is particularly practical. Whether for checking solvents, quality testing in the food industry or general laboratory analyses: the instrument proves to be a versatile tool.
Technical features at a glance
- Calibrated at 20 °C (Tp. 20 °C)
- Reading below the meniscus for increased precision
- Unit: g/ml, ideal for various laboratory applications
- Suitable for general laboratory and industrial use
- Not normalized, available without calibration certificate
- Robust construction for high durability
- Compact shape for easy handling
As the device does not have official certifications such as DIN or CE, a regular testing routine within your own laboratory or company is recommended. As a rule, many companies offer internal procedures to ensure that measuring devices work within their tolerance limits. This allows the operational safety and accuracy of the hydrometer to be verified even without official certification.
Examples of use in laboratories and industry
The hydrometer is suitable for a wide range of applications, both in scientific and industrial environments:
- Control of solvent densities: When synthesizing organic compounds or checking purity levels, the density can quickly provide information about the composition.
- Food analyses: For beverages such as fruit juices or liquid sweeteners, density can be used for quality control.
- Cosmetics production: Density is crucial for the correct consistency of creams, lotions or essential oils and can be checked with the measuring instrument.
- Pharmaceutical testing: When developing or testing the quality of pharmaceutical solutions, a precise density value can mean the difference between a successful formulation and a reject.
A variety of liquids are usually used in these processes, including ethanol, isopropanol or glycerine. The hydrometer quickly provides clear measurement data. As temperature is a critical factor for measurement accuracy, it is advisable to temper the samples to around 20 °C before each measurement.
FAQs
How accurate is the measuring instrument?
The device is designed for general use and generally provides measurement results that are sufficient for laboratory and production purposes. Although there is no official calibration certificate, an internal comparison with other reference devices can quickly confirm the accuracy.
Why is the reading taken below the meniscus?
Reading below the meniscus minimizes optical distortion and ensures a more reliable measurement result. This method prevents overestimation or underestimation of density, especially with clear or slightly colored solutions.
Is the hydrometer suitable for corrosive or aggressive liquids?
In principle, the measuring instrument is robust, but use in highly corrosive media can reduce the service life and lead to measurement errors. It is advisable to check the resistance of the individual components and use a suitable protective vessel if necessary.
Does the device need to be recalibrated regularly?
Although it is not normalized, a regular target/actual comparison with reference solutions is recommended to ensure measurement accuracy. In ultra-critical applications in particular, even a minimal deviation can have a major impact.
How do I maintain the hydrometer correctly?
After each measurement, the instrument should be cleaned with suitable solvents and then dried thoroughly. Make sure you only hold the device in the intended places to avoid damage or contamination.
