RKI Instruments FP-301 Gas Detector, Arsine 0-15 ppb, Paper Tape
Overview
The RKI Instruments FP-301 is a paper tape gas detector for arsine (0-15 ppb) and hydrogen selenide (0-200 ppb). An internal sample-draw pump pulls gas to the tape, and the LCD shows gas type and concentration digitally. The unit can be panel mounted on 24 VDC or used as a desktop type on 100 to 220 VAC.
Features
- Arsine detection 0-15 ppb
- Hydrogen selenide detection 0-200 ppb
- Photoelectric photometry with plug-in tape cassette
- Internal sample-draw pump
- Digital LCD gas concentration display
- Self diagnosis covering sensor failure, low flow, tape cut, tape end and system trouble, with a tape remainder display that warns before the cassette needs replacement
- Audible and visual warning and alarm, with common relay contacts for warning, alarm and trouble in latched mode rated 0.5 A at 125 VAC
- 4-20 mA output for connection to plant control systems
Applications
- Semiconductor fab toxic gas monitoring
- Gas cylinder storage and gas cabinet detection
- Process areas using arsine and hydrogen selenide
