FI-21
The Gas Detector Model FI-21 is a precision gas analyser which is adapted to measure the % volume concentration of any of the commonly used gas in a mixture of air or oxygen for solvents, fumigation, gas purity and anaesthetic gas.
List of Benefits
- Capable of measuring up to 8 kinds of gases
- Gas can be selected with key operation
- Direct digital readout
- Built-in sampling pump
- High accurate measurement with CCD and Fourier analysis technology
- Data logging stores up to 100 readings
- Few consumable parts saving on maintenance cost
The Gas Detector Model FI-21 is a precision gas analyser which is adapted to measure the % volume concentration of any of the commonly used gas in a mixture of air or oxygen for solvents, fumigation, gas purity and anaesthetic gas. The standard instrument is calibrated for eight (8) selectable gas readings on the direct digital display. The FI-21 operating principle utilises the highly accurate measurement with CCD and Fourier analysis technology and electronic circuitry to provide direct digital readout. The FI-21 is equipped with a built-in sample draw pump for ease of use.
Applications
- Measurement of gas concentrations for solvent gases, fumigation gases, etc.
- Measurement of gas purity
- Measurement of fuel calories
- Measurement of anaesthetic gases
