Oxygen Analyzer, electrochem , handheld

Handheld, battery powered device that measures the oxygen concentrationin a flow of gas from a medical gas source or, with adapters, through a medical gas-flow device such as a ventilator or anaesthesia system, or within an environment such as oxygen hood and infant incubator.

Operational characteristics:
Handheld oxygen analyzer for continuous measurement of the oxygen concentration from a medical gas source and in an environment.
Suitable for measuring gas supply with pressure up to 50 psi (344 kPa).
Response time: ≤ 20 s.
Electrochemical cell oxygen sensing technology.
O2 resolution: 0.1 %.
O2 measurement includes the range 0.0 - 100%.
O2 accuracy: within ± 3 %.
Warm-up time: none required
Display visualizing O2 concentration, system messages and battery status.
Internal calibration timer (weekly); alerts the operator, using a calibration icon on the LCD display, to perform a unit calibration one week after previous calibration.
Low and high oxygen concentration alarm system, with flashing LED and audible indication of alarm conditions.
Replaceable oxygen sensor cell, expected sensor life >1,500,000 O2% hours over 2 years in typical applications.
Calibration and self-test mode, one point calibration 20.9% or 100%.

Electrical characteristics:
Internal replaceable batteries, four AA alkaline batteries, single use.
Operated by battery power supply.
Sleep mode operation to extend battery life; in sleep mode operation, the unit will time-out after 90 seconds to a battery saving condition. In sleep mode, the device will continue to monitor the oxygen level and will activate the alarm if any alarm condition occurs.
Battery life: approximately 5,000 hours with typical use.
