Gas Volume AnalyzerGVA-710
Gas Volume AnalyzerGVA-710
This instrument automatically measures gas volume, internal gas pressure, air content, and oxygen concentration for quality control in the bottling process of carbonated drinks, etc.
Features
- Fully automatic measurement
Both gas volume and air content in a sample container can be measured with a single measurement.
No personal differences in measurement results by automatic measurement.
Less workload compared to manual measurement.
It is much safer compared to the manual method of less contact with alkaline solutions.
- Reduced measurement and preparation time
Reducing time by 30 to 70% compared to the conventional model when measuring air content.
- Support for a variety of samples
It can measure cans and PET bottles from 160 mL to 2.0 L.
Enable measuring sample container with a tamper-resistant cap (double-layered lid).
It can measure 500mL PET bottle lightweight containers.
- Output results to an external printer or PC using dedicated software
Measurement results can be output to an external printer and a connected PC using dedicated software.
- Method function
Up to 20 methods, depending on sample property and measurement items, can be registered in the instrument.
The measurement method can be edited on a PC using dedicated software.
- Support for barcode reader
Barcode information, such as sample ID affixed on the container, can be scanned and transferred using a commercial barcode reader.
- Visibility inside the absorbent cylinder
The dissolution status of carbon dioxide gas and air content in the absorbent cylinder can be visually checked by operators.
