Gas Volume Analyzer
GVA-700
Features
- 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.
The features of GVA-700 are as follows.
- No personal error/Fully automated measurement.
- Less work/Less possibility to contact alkaline solutions.
- Improved maintainability
With the detachable front cover, easy to maintain the sniffing valve and the filter. - Compact size, space saving
Size: 495(W) x555(D) x570(H) mm
(Conventional model : 670(W) x505(D) x680(H) mm)
Easy to secure the installation space with the slide cover. - Inside the absorption cylinder is visible.
Inside of the absorption cylinder can be checked visually. - Improved software
Store 20 methods and 100 measurement results. - USB flash drive
Load methods and store measurement results with a USB flash drive.
