Gas Volume Analyzer GVA-700

This measuring instrument automatically measures gas volume / internal gas pressure, air content and oxygen concentration for quality control in the bottling process of carbonated drinks, etc.

Only by setting a sample container on the sample stage, all the procedures are performed automatically; punching, depressurizing, stirring of a sample, absorption of measurement gas and so on.
By continuously rotating a sample container, the balance pressure of gas and sample temperature in the container are measured and calculated into gas volume / internal gas pressure, which are displayed on the LCD.
Furthermore, carbon dioxide in the sample gas is absorbed into alkaline solution to leave only nitrogen and oxygen, and then calculate air content using the residual gas volume and oxygen concentration, which are displayed on the LCD.
Data printing is available by connecting an external printer to the RS-232C port and 100 measurement results can be recorded in a USB flash drive via the USB port.

No personal error/Fully automated measurement.

Alcohol Meter ALM-155

The ALM-155 is a dedicated, small size & high-performance bench top density meter with oscillating capillary tube for the analysis of oenology, sprits and beer.

The analysis of Alcohol, density and specific gravity in alcohol products has never been so easy and accessible for any budget.

The ALM-155 displays results with high-resolution of 0.01% for alcohol content and 0.00001 g/cm³ for density.

Moreover, with the peltier thermostat system, the temperature is fixed at exactly 20°C/60°F.

One button measurement with small sample volume
The ALM-155 is equipped with peristaltic pump for automatic sampling. The required sample volume is only 8mL and can be used for repeatability testing with the automatic repeating function. The analysis of alcohol content (on the distilled wine sample) or density (on wine as it is) is performed in two to four minutes for one measurement by pressing just one button. When high viscous sample is measured, an optional syringe can be utilized to introduce the sample into the measurement cell what makes the ALM-155 suitable for the analysis of any alcohol products.

Simple calibration with pure water and easy maintenance
The calibration of ALM-155 does not require expensive standards, only pure water. After analysis, the unit can be cleaned by simply washing the cell with pure water or a kitchen detergent. The only replacement parts are the sampling tubes and those can be replaced by the user. The daily performance check can be easily performed by the operators and requires pure water only.

Automatic Saving results with digital data
The results are not necessary to be recorded by hand-writing. An optional printer can automatically print out the results once the measurement is completed. The ALM-155 can also store measurement up to 100. The data can be transferred to a connected USB memory stick or to an optional PC software through an RS-232C cable.

Wineries
Alcohol is the main legal parameter for bottled wines; the declaration of fake values entails severe penalties for wine producers. For this reason, the analysis of wine must be done in accordance with the official analysis method.
It is very important to check density, specific gravity and alcohol content during wine fermentation, in order to verify its progress and provide notice if it stops prematurely.

Must production
The density of grape juice indicates the amount of sugar contained in the juice before fermentation. It can determine the expected alcohol content in wines, so it is very important to analyze its density accurately.

Oenological labs
In addition to providing analytical support to wineries, these laboratories can release certificates of analysis with legal validity. As well as wineries, these laboratories have to perform analyses in accordance with the official method in order to be sure of the accuracy of the values they certify.

Distilleries and spirits
Companies producing spirits, such as distilleries, have products with a high alcohol content. The ALM-155 is a high performance instrument working in the whole concentration range from 0.00% to 100% alcohol content. Therefore, the instrument is highly suitable for this application.

Beer production
Monitoring density and specific gravity during the beer production process is very important for the quality of the final product. ALM-155 can provide alcohol testing after the beer sample has been distilled.

Vinegar making
Vinegar is obtained by oxidation of the ethanol content of wine, cider, beer, other fermented alcoholic beverages, or raw materials such as malt, rice and raw and cooked fruit. Checking the alcohol content during the oxidation process is very important to understand when ethanol has completely turned into acetic acid.
