PASPORT Oxygen Gas Sensor - PS-2126A

PS2126A_inuse_MAIN.jpg

Overview

Our Oxygen Gas Sensor accurately measures oxygen concentration in the atmosphere or in enclosed spaces, such as terrariums. The sensor's wide range (0-100%) means you can use it with any experiment or investigation. Use in combination with the CO2 Gas Sensor (PS-2110)  to perform an even wider variety of environmental and physiology activities in the classroom or in the field.

Typical Applications

  • Measure the respiration of animals, insects or germinating seeds
  • Study the catalase breakdown of hydrogen peroxide
  • Monitor O2 level changes during photosynthesis in a terrarium
  • Study cellular respiration of yeast

Probe life expectancy

The sensor is guaranteed for a minimum of 2 years from the date of manufacture. This is the absolute guarantee. If it is used in a 100% oxygen atmosphere its life will be shortened. If it is used in normal air, its life will be 4 to 5 years. There is reported evidence of this particular sensing element being in use for almost 10 years. In the end, the useful life of the sensing element is dependent on the manner in which it is used.
