RKI FP-300 Paper Tape Gas Monitor Gas Type:Boron Trifluoride (0-3 ppm) Check your electrode model beforeThe RKI FP 300 is a continuous paper tape gas monitor that uses photoelectric photometry against a plug in chemcassette tape to detect toxic gases at trace concentrations, with roughly one month of tape life before replacement and an onboard tape remaining display with end of tape warning. Latching or self resetting alarms drive yellow caution and red warning lamps, a buzzer, relay contacts, and a 4 20mA output. Available in gas specific tape versions
