LabQuest Sensors
The CO2 Gas Sensor measures gaseous carbon dioxide levels in two selectable ranges of 0 to 10,000 ppm and 0 to 100,000 ppm (which covers human breath).
Ideal for measuring changes in Carbon Dioxide levels during plant photosynthesis and respiration. You can easily monitor changes in CO2 levels occurring in respiration of organisms as small as crickets or beans! The CO2 Gas Sensor is easily calibrated using a calibration button. A chamber is included for running controlled experiments with small plants and animals.

The Conductivity Probe determines the ionic content of an aqueous solution by measuring its conductivity. This has many applications in chemistry, biology, and environmental science.
The Conductivity Probe has three ranges, providing optimal precision in any given range. Biology teachers can use this probe to demonstrate diffusion of ions through membranes. Chemistry students are able to quickly investigate the difference between ionic and molecular compounds, strong and weak acids, or ionic compounds that yield different ratios of ions. Environmental science students use it to measure TDS, total dissolved solids.

The Vernier Optical DO Probe uses luminescent technology to provide fast, easy, and accurate results, making it a terrific choice for biology, ecology, or environmental science courses. Students can measure dissolved oxygen concentration in surface water or to perform a wide variety of experiments to determine changes in dissolved oxygen levels, one of the primary indicators of the quality of an aquatic environment.
Using Plug and play technology, no filling solution is required, no warm up time needed, no stirring and no calibration.

The Gas Pressure Sensor can be used to monitor pressure changes in a gas. The range is wide enough to perform Boyle's law yet it is sensitive enough to conduct vapor-pressure or pressure-temperature experiments. Biology teachers can use the Gas Pressure Sensor to monitor transpiration or respiration in an enclosed environment.
