SERIES 3500 and 3510

sensors are their inability to measure oxygen in gases containing carbon dioxide. Carbon dioxide reacts with potassium hydroxide electrolyte to form carbonic acid and in short time destroys the sensor. Not anymore. Alpha Omega Instruments offers an optional CO 2 tolerant trace oxygen sensor with proprietary electrolyte. The CO 2 tolerant ...


Oxygen Monitor with Water Proof enclosure 025% for ...

The PureAire Combo O2/CO2 oxygen sensor requires no quarterly calibration or annual maintenance and the CO2 sensor automatically adjusts to ambient levels. All you need to do is plug in the monitor and let it run in the background—no maintenance needed! Sampling Method Range. Sample 025% O2 010,000ppm CO2. Accuracy.


NEMA4 v IP65 Enclosure Comparison |

Many of our wallmounted meters are listed as NEMA4 or IP65 enclosures. These designations describe the level of protection the "boxes" give to internal electronics. Here are the differences. NEMA4 Indoor or outdoor use to provide a degree of protection to personnel against access to hazardous parts To provide a degree of protection of the equipment inside the enclosure against ingress of ...


Gas Analysers and Systems MTL Inst

2019513 · The GIR250 is designed to monitor percentage levels of oxygen and carbon dioxide in a single, robust unit. Oxygen is measured with a special electrochemical cell which works in the presence of mildly acidic gases such as carbon dioxide. The carbon dioxide is measured by NDIR sensor. A dual display gives % resolution on each gas.


O2 and CO2 Sensor Integrated Mask for Aiding ...

2021921 · sensors are routed to the back of the head where the enclosure is mounted. The enclosure contains the main board, the accelerometer, and the battery. The carbon dioxide and oxygen sensor measures the expired gas levels of the user (in ppm) and the …


3350 Control Room Oxygen Monitor

2  · Control Room Oxygen Monitor . The Model 3350 accurately measures the concentration of oxygen in control rooms, closed atmospheres, critical breathing circuits and other applications that require the failsafe monitoring of breathable, ambient air. It is a microprocessorbased oxygen alarm monitor for realtime measurement of the oxygen content ...
