ASGU-370P

Automatic Span Gas Unit for Parallel calibration

The multi point calibration unit ASGU-370P is designed for simultaneous (parallel) checking of several gas analyzers. It is primarily installed in laboratories for quality assurance and is also used for the production of gas analyzers.

The calibration unit ASGU-370P will be used for the dynamic and continual manufacture of zero and span gas to perform among other things all ongoing quality control procedures according EN 14211, EN 14212, EN14626 and EN 14625. To produce various span gas the unit uses technologies like dilution, permeation, UV irradiation or Gas Phase Titration.

Multipoint calibration acc. EN 14211, EN 14212, EN14625 and EN 14626
High accuracy of span gas in cause of usage of factory calibrated digital thermal mass flow controllers in high quality
One 3 HU unit for calibration of several analyzers. Low space requirement.
Simultaneous operation in cause of independent layout of channels (modules)
Comfortable operation via big, illuminated Touch-Screen-Display or externally from analyzer
Operation via RS232 and Ethernet interface (Bayern Hessen protocol)
Delivery scope includes remote software for easy external handling (Ethernet)
High flexibility by free definable span points (up to 20)
High flexibility by free definable cycles (e.g., Lack of fit)
High flexibility by free definable sequences (stringing cycles together)
Programmable timer allows time shifted start of calibration process
Internal data logger (option) stores raw values from calibration procedure (set values and actual values, status) for reporting with evaluation software (included in scope of delivery)
Adapted to customer’s request
Modular Layout enables later upgrade with additional span gas modules

During the period of rapid economic growth, Japan was burdened with various types of pollution such as water contamination and air pollution. The first step to regain the glow of the sky and the purity of water was analysis. HORIBA's measuring instruments play an active part in various fields to determine, for example, whether established regulations are complied with or whether the air and water are purified properly. The beautiful environment is the world's asset. Going forward, HORIBA will continue contributing to preserving the global environment through measurement.
