Sensor Dos and Don'ts


Read and understand the leaflet before using the sensor

Visually inspect the sensor for leakage before each use

Recalibrate device after replacing the sensor

​Use sensors ​if they are not in original package

Use sensors if electrolyte loss is observed

Immerse the sensor in any liquid

Pass hot or cold gas mixtures over the sensor

Autoclave or freeze the sensor

Place the unit in a water vapor-saturated environment

Use cleaning agents or liquids to clean the sensor or the board

Open or try to repair a leaking or broken sensor

Attempt to use the sensor if the output of the sensor is erratic and unstable when exposed to a calibration gas

Attempt to use the sensor outside of the maximum ambient conditions which manufacturer specifies

Use the sensor when it has been exposed to a drastic change in the environmental conditions without allowing an equilibrium condition to have been reached

Allow moisture to accumulate on the sensor sensing surface

Gases That May Induce Reading Errors

When using Teledyne's medical oxygen sensors in the presence of anesthetic gases, the oxygen reading may fall (see table below). The magnitude of this error will depend upon the level of oxygen and the duration of exposure.

The anesthetic agents listed in the following table (Halothane, Enflurane, lsoflurane, Sevoflurane, and Desflurane) were vaporized into a stream of 30% oxygen / 70% nitrous oxide, and the resulting drops in oxygen level after an exposure of approximately two hours were noted.

Exposures in excess of two hours may produce slightly greater errors. The errors listed are typical for all Teledyne medical oxygen sensors. Exposing the sensor to air or gases that do not contain anesthetic agents for a period of time equal to or greater than the exposure interval will eliminate the reading error in most cases.​
